How to Test an AC Capacitor?

How to Test an AC Capacitor: Easy Step-by-Step Guide

Air conditioner capacitors store electrical energy, and when they malfunction, it can cause your AC unit to run inefficiently or not at all.

Testing an air conditioner capacitor is relatively simple.

Nevertheless, it will require you to know a few things about your AC unit first.

By understanding how an air conditioner capacitor works and what tools are needed to test one, you can quickly identify any issues before they become unfixable.

This guide will provide step-by-step instructions on how to test both start capacitors and run capacitors.

We’ll also discuss different types of AC capacitors and their function in the overall operation of an air conditioning system.

Keep reading to learn how to diagnose a capacitor problem in your AC.

What is an AC Capacitor and How Does It Work?

An air conditioner capacitor is an essential component of a home air conditioning unit.

It is typically found near the fan blades or coils of the AC unit.

Its primary function is to store and supply power for your system’s motors.

In simple terms, it acts as a surge protector, providing a jolt of electricity to get your AC up and running when you first turn it on.

The amount of electricity required to turn on an AC can be quite high.

As such, the capacitor helps reduce this load by storing energy in powerful bursts.

This helps increase the speed at which your air conditioner starts up.

It can also help with reducing wear and tear on its components.

After the initial start-up phase, the capacitor reduces its output to a steady current that powers your system until it shuts off.

Air conditioner capacitors come in different sizes and are measured in voltage and microfarads (MFD).

Voltage measures how fast electrical current moves through the capacitor.

Meanwhile, MFD indicates how much electrical current it can store.

Most capacitors range from 5 MFD to 80 MFD, depending on their size and model.

A larger capacitor will typically have more voltage and MFD than smaller models.

This means they can handle higher loads of electricity without overloading the system or causing damage.

While all capacitors serve similar functions, they should not be used interchangeably.

Since they are designed for certain types of air conditioning systems, using them on an incompatible system can lead to irreversible problems.

If you’re unsure about what type of capacitor is right for you, contact your local HVAC specialist.

They can help you identify what type of capacitor works best for your AC unit.

What Is a Dual-Run Capacitor?

A dual-run capacitor is a combination of two capacitors in one unit.

It powers the fan motor and compressor motor simultaneously, helping reduce the amount of energy needed to start up your AC unit.

Dual-run capacitors are more common than single-run models as they help improve efficiency while also reducing wear and tear on the components.

Start and Run Capacitors: What Are They?

Modern AC units have two types of AC capacitors: a start capacitor and a run capacitor.

Let’s look at each type before moving on to our step-by-step guide:

Start Capacitor

A start capacitor is a temporary capacitor that helps get the motor running.

This type of capacitor has a higher voltage rating and will only be used for a few seconds when you first turn on your AC.

Run Capacitor

The run capacitor, on the other hand, works to maintain continuous power flow to the motor after the initial start-up phase.

It has a lower voltage rating and stays charged until the AC is turned off.

Its main function is to ensure that the fan or compressor motor runs efficiently without straining or overheating.

Step-by-Step Instructions on How to Test AC Capacitor

Now that we’ve gone over what an AC capacitor is and the two types of capacitors used in modern ACs, let’s take a look at how to test the capacitor.

Materials & Tools Needed to Test an AC Capacitor

To test an AC capacitor, you’ll need the following materials and tools:

  • Multimeter
  • Insulated gloves
  • Voltage tester
  • Screwdriver
  • Pliers

Step 1: Wear Insulated Gloves

Before beginning, make sure to wear insulated gloves for safety.

Additionally, double-check that your AC has been turned off, to avoid harmful and unwanted accidents.

Step 2: Locate the Capacitor

As mentioned earlier, the capacitor is typically found near the AC fan motor or compressor.

Use your screwdriver to open your AC unit and find the AC capacitors.

You’ll see some wires connecting your AC components to the start and run capacitor.

Take a picture of the wires to use as a reference when you reconnect them later.

Step 3: Discharge the Capacitor Terminals

Capacitors that are in good condition can carry charges for hours up to months after being unplugged from their main power source.

Before anything else, make sure to discharge the capacitor terminals to avoid harmful accidents.

Using the metal shaft of your screwdriver, short the terminals connecting your AC unit to the capacitors.

Keep your fingers as far away from the screwdriver’s metal shaft as possible.

It may take a few minutes for the energy to evacuate the air conditioner capacitor.

Step 4: Check voltage rating and Remove Wires

Check the voltage on the capacitors using a voltage meter or multimeter.

Using a pair of pliers, remove the wires connected to your air conditioner capacitor.

Now, you can test your capacitor’s “capacitance” levels.

Step 5: Set Multimeter

You can use two types of multimeters to test a capacitor: an analog or digital multimeter.

A digital multimeter is easier to use than an analog meter. However, we’ll walk you through how to use each type.

How to Use a Digital meter

Set your digital meter to “capacitance.”

Using the probes provided with the multimeter, touch one end of each capacitor terminal.

If the readings are below the stated capacitance setting on your AC manual, you likely need a new capacitor.

How to Use an Analog meter

If you’re using an analog meter, connect the probes to each capacitor terminal.

Turn your dial until you reach the capacitance setting and observe the needle’s deflection.

Again, if the needle does not move far enough or points below the stated capacitance value on your AC capacitor, it likely needs replacement.

Tips for Troubleshooting AC Capacitor Issues

If you experience any issues while testing your AC capacitor, here are some tips to help troubleshoot them:

  • Make sure all connections are secure and firmly in place.
  • Inspect the capacitor for any signs of corrosion or damage to the casing.
  • Check that all wiring is intact and properly insulated.
  • Use a quality multimeter to ensure you’re getting an accurate reading.

When all else fails, it is best to seek professional help from an HVAC technician.

Signs of a Bad AC Capacitor

A bad AC capacitor can be tricky to spot. Fortunately, there are signs that can help you identify an AC capacitor problem.

Compressor or Condenser Fan Motor Won’t Start

The first sign you’ll notice when dealing with a bad AC capacitor is a dysfunctional compressor or fan motor.

Since your AC capacitor is not supplying enough energy for either component, it makes it harder for them to maintain functionality, if they manage to turn on at all.

Insufficient Cooling

Another sign that your AC capacitor has gone bad is if your AC stops producing enough cold air for your home.

This is because your unit might not be receiving sufficient energy to keep things running.

Higher Energy Bills

The condenser fan motor has to work harder to make up for a faulty AC capacitor.

You can expect lesser efficiency and higher energy bills as a result.

Since your fan motor needs to work twice as hard to keep up with the demands of your home, a faulty capacitor can also shorten the life expectancy of your unit.

In other words, you may have to replace your AC unit sooner than you thought.

When to Seek Professional Help

If the AC capacitor in your system has gone bad, it is best to replace it as quickly as possible.

Testing an AC capacitor is not a difficult task as long as you know what you’re doing.

If you arm yourself with the right materials and tools, as well as understand how to use them properly, you can easily test your AC capacitor for any faults.

If all else fails, seek professional help from an HVAC technician who can handle the job safely and efficiently.

A specialist can also detect any other underlying issues in your AC unit that could be causing a problem and make the necessary repairs.

Reliable and Effective Solutions to All Your HVAC Needs

Having a malfunctioning air conditioner can be incredibly frustrating and inconvenient.

Not only is it uncomfortable, but you also run the risk of higher energy bills due to inefficient cooling.

Plus, if your AC capacitor has gone bad, it could shorten the life expectancy of your unit and require costly repairs or replacements.

How Much Does It Cost to Replace AC Capacitor?

Comparing Prices and Options for HVAC Repairs

An AC capacitor is a vital part of the Heating, Ventilation, and Air Conditioning (HVAC) system.

Without a capacitor, your AC unit won’t be able to turn on or run efficiently.

But if you’re like most people, you probably don’t know much about your air conditioner capacitor — let alone how much it costs to replace it when it starts to fail.

In this article, we’ll look at AC capacitor basics: different types available on the market today and associated costs for replacement parts and installation services.

Keep reading to learn more about the costs of AC capacitor maintenance and repairs.

What is an Air Conditioner Capacitor?

An AC capacitor is like a battery that provides the initial jump of electricity to start and run the AC system. It also helps keep it running steadily by controlling the amount of power going into the compressor motor.

How Long Does An Air Conditioner’s Capacitor Last?

Generally speaking, an air conditioner’s capacitor lasts around 10 years or longer. Age and usage will play a big role in how long they last.

If your AC capacitor is more than 10 years old, it may be time to start looking into AC capacitor replacement costs and options.

Types of AC Capacitors

The three main types of AC capacitors are run capacitors, start capacitors, and dual-run capacitors.

Run Capacitor

The run capacitor is responsible for keeping the AC compressor motor running smoothly.

It helps regulate the electrical current that is needed to power the AC compressor motor consistently.

Start Capacitor

The start capacitor provides an initial burst of energy when starting up your AC unit, allowing the AC blower to begin circulating air.

Dual Run Capacitor

A dual-run capacitor is a combination of both a start capacitor and a run capacitor. The great thing about dual-run capacitors is that they can run larger AC units thanks to its larger power supply.

Unfortunately, if one part fails, you will have to replace the whole thing. This may mean more expensive AC repair costs.

Signs of a Bad AC Capacitor

A common sign of air conditioning capacitor failure is a sudden decrease in AC performance.

If your AC unit is no longer cooling or heating as it should, it may be due to a faulty HVAC capacitor.

Other signs can include:

  • Loud humming or clicking noises coming from the AC unit
  • Delayed fan start-up times
  • AC doesn’t turn on
  • AC shuts off randomly
  • AC doesn’t produce cool air as efficiently
  • A burning smell coming from the AC unit
  • Higher energy bills
  • Gas leakage

If you notice any of these signs, it might be time for an AC capacitor replacement. Contact an HVAC contractor to help diagnose your problem.

How Much Does It Cost to Replace AC Capacitors Alone?

Standalone AC capacitor prices generally depend on the type and model you’re planning to buy.

The capacitor’s brand and voltage may also affect its price.

If you plan to replace an AC capacitor in your HVAC system, you must consider these factors in your budget.

Here’s a closer look at how much each capacitor type is:

Costs for a New Dual Capacitor

Dual capacitors can cost around $15 to $45.

They’re the ideal choice for large HVAC systems as they can easily power both the compressor and fan motors simultaneously.

You have several options for where to buy the parts.

You can visit a local AC parts store or shop online from various AC part suppliers.

Costs for a New Start Capacitor

You can buy a start capacitor at a slightly cheaper price than dual-run capacitors.

For parts alone, you can expect to spend around $9 to $25.

Location, labor, voltage, and other factors can affect these numbers.

Request a quote from your HVAC services provider before finalizing any decisions.

Costs for a New Run Capacitor

Run capacitors are responsible for maintaining the proper energy supply in your air conditioner system.

Buying a new run capacitor can cost you anywhere between $6 to $30.

Other Factors That Affect AC Capacitor Cost

There’s more to consider than just capacitor prices alone when trying to determine the overall costs of replacements.


Location is a major factor that affects AC capacitor prices.

Depending on where you live, AC parts may be more expensive due to higher demand or lack of AC repair contractors.

Hotter climates typically require ACs to run year-round, which can increase AC repair costs as the demand for AC services increases.

Similarly, living in an area with a higher cost of living can lead to more expensive AC capacitor replacement costs.

AC Type and Size

AC capacitor cost can vary depending on an HVAC system’s type and size.

Larger AC units may require more expensive capacitors to power their systems.

Meanwhile, smaller ACs can get by with cheaper AC parts.

AC units that are older models will most likely need to use an AC capacitor designed for those types of ACs.

This can be harder to find and may need to be custom ordered. Thus, it may cost more than traditional parts.


AC capacitor cost can increase significantly during the summer. That’s because AC contractors are busy and more people need AC repair when it is hot outside.

If you want to save on replacement and repair costs, consider getting services during off-peak seasons.

AC Capacitor Cost: DIY Replacement

Some homeowners prefer DIY air conditioner capacitor replacements.

While it’s true that DIY repairs and replacements can save some people money, it’s not always the best solution.

You can replace an old or malfunctioning AC capacitor for as little as $60 to $100. This saves you around $60 to $200 in parts and labor costs.

However, taking things into your own hands means you need to take extra care when conducting repairs.

The slightest mistake can set you back several hundred dollars.

Additionally, if you don’t already have the necessary tools to conduct DIY repairs, you need to set aside a budget for it.

Materials and Tools Needed

Tools and materials can also affect your AC capacitor replacement cost.

Here’s a general list of tools you’ll need with their corresponding prices:

  • Electricians Safety Gloves ($20)
  • Insulated Screwdriver ($15)
  • Nut Driver ($5)
  • Safety Glasses ($10)

These prices are not fixed. Your location, the brand you buy, and the date that you buy will affect the tool prices.

AC Capacitor Cost: Professional Replacement

If researching how to properly and safely replace an AC capacitor is not your style, you can always ask a professional to help.

Depending on their level of experience, assistance from a professional can cost you anywhere between $60 to $200.

Transportation, tools, parts, and union are typically charged separately.

DIY vs Professional AC Capacitor Replacement: Which Is Better?

There is no one-size-fits-all answer to this question.

It all depends on your AC repair needs and your skill set. If you’re comfortable with DIY AC capacitor replacements, then go for it!

On the other hand, seeking help from a professional AC repair contractor can give you peace of mind that the AC capacitor replacement is conducted in a proper and safe manner.

This could save you money in the long run, as well as prevent any future AC repair problems.

Whether you decide to go for DIY or professional AC capacitor replacements, always remember to compare prices and options from different sources.

This can help you find the best AC capacitor replacement for your AC unit.

How to Save Money on AC Capacitor Replacement Cost

We understand why most people would want to avoid getting professional services.

Most people aren’t willing to pay for professional AC capacitor replacement costs.

However, there are still ways you can save on professional services when you need to replace an AC capacitor:

Buy Your Own Replacement Capacitor

To save money on a professional AC capacitor replacement, purchase your own AC capacitor and hire an experienced HVAC technician to do the installation.

How to Diagnose a Low Freon Problem in Your Home Air Conditioning Unit

Are you worried that your home air conditioning unit might have a low Freon problem? Don’t worry – it’s not as difficult as it may seem.

In fact, with the right tools and knowledge, anyone can diagnose their AC and identify potential problems.

This article will provide an easy-to-follow guide on correctly diagnosing your system and pinpointing any issues related to refrigerant levels or blockages in the refrigerant lines.

We’ll also discuss the importance of proper maintenance for air conditioners and provide tips on how to prevent future problems from occurring.

What is Freon?

Freon is a refrigerant used to cool your home. It’s often referred to as a “refrigerant gas” or “coolant” and is found inside most AC systems.

It is a colorless, odorless gas and was first developed in the 1930s. It is referred to by its chemical name, dichlorodifluoromethane (CFC-12), and is one of the most widely used refrigerants in the world.

Freon works by evaporating and condensing rapidly to create a cooling effect. This process is known as vapor compression refrigeration.

When the compressor in your system compresses freon gas, it increases its temperature and pressure. The new hot and pressurized freon then travels through a series of coils.

As this happens, heat is released outside while cooler air flows into your home or building’s interior spaces. The newly cooled air is then sent back to the compressor where it begins the cycle all over again.

What Causes Freon Problems in Air Conditioning Systems?

If your AC unit is running inefficiently or isn’t cooling correctly, it could be due to a low refrigerant issue. Low levels of freon can be caused by several things, including:

  • A leak in the evaporator coil
  • Refrigerant blockages
  • Improper maintenance
  • Poorly installed units

How to Diagnose a Low Freon Problem

In order to properly diagnose a low freon problem in your AC system, you’ll need the following tools:

  • An AC pressure gauge
  • A thermometer
  • A vacuum pump

Step 1: Check for Leaks

The first step in diagnosing a low freon problem is to check for leaks. Begin by inspecting all of the refrigerant lines and joints. Look for any signs of wear or damage that could be causing a refrigerant leak, like cracked seals or loose fittings.

If you find any visible signs of a leak, the next step is to use the pressure gauge. Connect it to the refrigerant line and check for a drop in pressure from one side of the system to the other. If you see a significant difference, this could be an indication that there is a leak in the line.

Step 2: Check for Blockages

After checking for leaks, the next step is to check for blockages. Start by checking all of the refrigerant lines and making sure that there aren’t any foreign objects blocking the flow of freon gas. You can also use a thermometer to measure the temperature of each line. If it’s significantly cooler than the outside air, this could be an indication of a blockage.

Step 3: Check for Proper Maintenance

If you haven’t been regularly maintaining your AC system, this could also be causing problems with the refrigerant levels. Make sure that you have had your AC unit serviced by an HVAC technician at least once per year in order to ensure that it’s running efficiently and the refrigerant levels are correct.

Step 4: Check for Poor Installation

If your AC system was not properly installed, it could also cause problems with your AC’s refrigerant levels. Make sure that all components are properly configured and connected during installation to ensure optimal performance.

Step 5: Use a Vacuum Pump

If all of the above steps have been completed and you still haven’t been able to diagnose the problem, then your last option is to use a vacuum pump. This tool will help to remove any air or moisture from the system and can help to identify any leaks or blockages that may be causing the issue.

Low Refrigerant Symptoms: What You Should Know

It’s important to be aware of the signs of low refrigerant problems in your AC system. Common symptoms include:

  • AC produces warm or hot air instead of cold air
  • Unusual noises coming from the unit
  • Increased energy bills
  • Ice on your evaporator coil

Let’s take a closer look at each sign:

Reduced cooling power

Is warm air blowing from your AC? The first sign you’ll notice when your AC unit is low on freon is reduced cooling power. This is when your AC produces lukewarm or warm air instead of cool air. You can use a thermometer to check the air temperature of your unit.

Another symptom of a low freon problem is poor air circulation. This means that your AC unit isn’t efficiently distributing the air throughout your home or office. You may notice that certain areas of your space are not cooling properly, while other areas are over-cooled.

Unusual noises coming from the unit

Leaking freon lines is a common cause of low refrigerant problems. This means there is refrigerant escaping somewhere in the coils. As a result, your AC won’t have enough refrigerant to carry out its duties.

When there’s a refrigerant leak, you will often hear an unusual bubbling sound or hissing sound coming from your HVAC system.

If you do, turn off your AC unit and contact an HVAC expert immediately. An expert can help you spot the leak and patch it up quickly and safely.

High energy bills

Are your utility bills suddenly higher this month? This could also be a sign of a low refrigerant problem in your AC system.

Air conditioners need freon to effectively cool your home. If there’s a shortage of it in your AC unit, your system will work twice as hard to compensate for the cooling demands in your home.

Not only can this increase your monthly energy bills but it can also cause the early deterioration of your system’s components.

Ice on your refrigerant lines

If you see ice or frost forming on your refrigerant lines, this is a surefire sign of a freon problem.

This usually happens because the AC unit isn’t able to adequately cool the air inside your home so it begins to freeze the refrigerant lines instead.

To fix this issue, you’ll need to contact an HVAC technician to refill your air conditioner’s refrigerant and perform necessary repairs.

What to Do If Your Air Conditioning System Is Low on Refrigerant?

If you’ve identified that your air conditioner is low on refrigerant, it’s important to take action quickly. The best course of action is to contact an HVAC expert as soon as possible.

An experienced technician can diagnose the problem and help you decide on the best solution for your situation. They will also be able to repair any damage and ensure that your AC unit is running efficiently.

Can I Refill the Freon in My Air Conditioner?

While it’s perfectly possible for you to refill the freon in your air conditioner, it’s not exactly legal.

According to EPA regulations, only a certified HVAC expert is allowed to change the refrigerants in your air conditioning system.

We strongly advise against changing the freon in your air conditioner alone. If you suspect that your unit is already low on freon, we would be more than happy to assist you!

How Often Should the Freon in My AC Be Refilled?

It is recommended that you check the freon levels in your air conditioner once a year. This should be done during the spring or summer months when your AC is being used more frequently.

If you notice any of the signs and symptoms mentioned above, it’s important to contact an HVAC expert right away so they can check the level of refrigerant in your AC and refill it if necessary.

By regularly checking the freon levels in your AC, you can help maintain a healthy, cooling system for years to come.

Benefits Professional HVAC Services

When it comes to air conditioning problems, professional HVAC services can provide you with the fast and efficient solutions you need.

An experienced technician can not only refill your unit’s refrigerant but also make sure that all other parts of your system are functioning properly. This is especially important if you want to prevent future air conditioning problems from occurring.

How to Refill AC Refrigerant

Can’t Beat the Heat? Here’s How to Recharge your Home Air Conditioner 

Picture this: It’s summertime. The sun is shining, the temperatures are rising, and it’s getting harder and harder to stand the heat. When the fan has been doing nothing but blowing hot air around the house, you finally decide to turn on the AC. You wait for hours, but somehow, your house isn’t getting any cooler. What could be the problem?

Owning a home air conditioning unit is a huge convenience, especially in places where summers can go up to 95 degrees. However, it’s very important to be on top of all repairs and maintenance to ensure the longevity of your unit. If you’ve been diligent with maintenance but your unit is still not cooling as intended, maybe it’s time to recharge your AC.

What does recharging your AC mean?

Recharging your air conditioner means refilling your unit’s refrigerant, which is the main component that cools your house. With the help of your AC’s evaporator and condenser, the refrigerant constantly changes from one state to another to absorb the heat from your home and convert it into cool airflow.

A lot of people still refer to refrigerant as Freon, as it has been the main refrigerant that has been used in residential air conditioners for many years. However, studies have shown that Freon or R-22 is extremely bad for the environment; thus, it has been phased out by manufacturers worldwide.

As of 2020, manufacturers no longer make Freon or Freon-compatible AC units. Modern air conditioners instead use Puron or R410A, which is safer for the ozone layer but still provides the same level of cooling.

Although the production and importation of Freon are banned in the United States, Freon can still be found for sale online or under certain conditions. However, for those with older AC units, it is recommended to upgrade to a more modern unit to avoid using R-22 altogether.

Whether your unit requires R-22 or R410A, it is designed to hold refrigerant for its entire lifespan. If you need to recharge your AC, that means there’s been a leak in your system that’s contributing to the refrigerant loss.

Before you set out to refill your refrigerant, you need to do a leak repair first. Adding refrigerant to a leaking unit can cause even more damage. It is important to consult technicians to conduct check-ups and AC repairs to avoid further damaging your unit.

How to know if it’s time to recharge your AC

There are a few ways to diagnose if your AC needs a refrigerant refill. Although some symptoms don’t necessarily mean your AC is leaking refrigerant, it is important to still watch out for one or more signs so that you can attend to the problem as soon as possible. Here are some issues that can mean it’s time to recharge your unit:

  • Your air conditioner runs the whole day, but it’s not effectively cooling your home or it’s blowing warm air
  • You find ice or frost buildup on the refrigerant line
  • You find water leaks from melted ice around your unit
  • Your electric bill may be higher due to your AC operating inefficiently
  • You hear concerning sounds like gurgling, hissing, or bubbling coming from the refrigerant line

How do you know if the refrigerant is the problem?

Sometimes your AC not cooling your home can be fixed by simply cleaning the unit and its air filter. However, if you have done your routine cleaning but your AC is still not working, this may be a surefire sign to have your refrigerant refilled.

Another sign to look out for is if the weakening of your unit’s cooling system is gradual. Sometimes, an AC’s decreased cooling ability is caused by a broken thermostat. If that is the case, your unit may lose cooling very suddenly or have its output temperature fluctuate. In contrast, a slow and gradual decline in cooling ability signals refrigerant loss over time, which points to a leak.

If you’re unsure, schedule a check-up and AC maintenance session with certified technicians to pinpoint the real cause of your AC issues.

How to Recharge your Home AC

If in doubt, don’t do it yourself. Refrigerants are dangerous substances, and if you’re not careful, you can sustain injuries that would need serious medical attention. Refrigerant inhalation can lead to headaches, breathing difficulties, nausea, vomiting, and coughing. Longer exposure can even lead to more severe effects like brain damage and sudden death. Meanwhile, physical contact with refrigerants can severely irritate the eyes and skin.

In general, recharging air conditioners is a dangerous procedure not just for your health, but also for your unit, since doing the procedure incorrectly can add damage to your AC.

It is highly recommended to hire skilled and certified technicians to recharge your AC for you. The United States Environmental Protection Agency (EPA) requires all professional technicians to be certified, so you can rest easy knowing your unit is in safe hands.

Technicians can also start with a broader diagnosis of your unit and can facilitate the leak repair before refilling the refrigerant.

However, if you are confident in your DIY and AC maintenance skills and you have access to the right equipment, you can try your hand at recharging your air conditioner. As long as you are correctly handling modern refrigerants, there is no law preventing you from doing this procedure at home.

Here are the steps you need to take before you refill your AC refrigerant:

  1. Make sure the AC is clean and maintained.
  2. Choose the correct refrigerant & prepare the right tools.
    • For this procedure, you will need a refrigerant gauge set with 3 valves and a canister of refrigerant. You may also need an electronic leak detector.
    • Make sure that you have the correct refrigerant for your unit. If you’re unsure, check your device manual or check your unit for more information. Certified technicians can also determine this for you.
    • If you have an older unit, you may need R-22, which can be difficult to source since you will need EPA certification to do so. In this case, you will have to hire a maintenance service to do this for you.
  3. Check the temperature outside your home.
    • Refrigerants are attracted to the coldest temperatures. Normally, this will be the inside of your AC unit, which is where the refrigerant should be. If it’s too cold outside, your refrigerant may behave erratically and get attracted to the outside environment.
    • Schedule your AC recharge when the temperature outside is above 55 degrees Fahrenheit so that the refrigerant remains in your unit.
  4. Wear protective gear.
    • To avoid any injury, prepare thick gloves, safety goggles, long-sleeved protective clothing, and a respirator before you start the procedure.
    • In case you come into physical contact with refrigerant, rinse the area immediately and seek medical attention. In case of accidental inhalation, go to a well-ventilated area away from the refrigerant and seek medical help.

Once you have everything ready, it’s time to start recharging your AC. Here is a step-by-step guide that you can follow:

  1. Start the procedure by turning off your AC unit. Then, make sure to turn off its power source at the breaker and thermostat.
  2. Hook your refrigerant gauge to your AC. Only connect the left (blue) and right (red) tubes and leave the middle valve open for now.
  3. Wait 15 minutes, then turn the AC back on. Let it run for a while so you can get an accurate reading on your gauges.
  4. Attach one end of the yellow hose to the refrigerant canister and another end to the center valve.
  5. Open the low-pressure valve (left side). Do so intermittently until you reach the right subcooling temperature on your gauge. To find out the correct temperature, check your outdoor unit’s rating plate.
  6. Once you reach the correct subcooling temperature, switch the valve off.
  7. Close your refrigerant canister. Then, disconnect all hoses from their valves & remove the gauge from your unit.
  8. Conduct a leak test using an electronic leak detector. Doing this will ensure that the refrigerant is staying in your unit and not escaping. You can also hire a technician to do this for you.
  9. Store your refrigerant responsibly. Each canister comes with instructions for proper storage. Refrigerant canisters are pressurized and need to be put away in the right conditions to avoid accidents. Some refrigerants are also flammable, so make sure to read the canister properly.

After refilling the refrigerant, observe your air conditioning unit and see if it’s cooling effectively again. If everything has been done correctly, you can now sit back and enjoy the comfort of a cooled home.

Preventative Maintenance for your AC

When temperatures soar, nothing beats the comfort of an air-conditioned home. To make your AC unit last longer, you need to conduct regular cleaning and maintenance. The air filters need to be cleaned or replaced every 1-2 months, while the interior of your AC unit has to be cleaned at least once a year, which is best done before summer.

Air conditioners require high-quality and constant maintenance. While you can clean filters yourself, it can get hard to find time to do full AC maintenance on your own, especially if you run into more complex problems like leaks and mold.

Licensed air conditioning technicians can help you properly maintain your unit. They know how to dismantle, clean, and reassemble your unit’s parts correctly. Moreover, they can provide assessments and diagnose if your air conditioner has any other problems that need attending to.

With regular care, a good air conditioning unit should last up to 10-15 years.

How to Prepare Your Furnace for Winter?

If it’s suddenly cold outside, that’s a sign to brace yourself because winter is coming.

While most of the year you can rely on steadily warm and humid weather, the incoming months starkly contrast with what you are used to all year. A Utahn winter season can be grueling for you and your heating system.

If your furnace has laid dormant during warmer months, get to dusting and tidying all that dust for seamless heating.

Here are some furnace maintenance tips to prepare it when the temperature drops.

Pre-Winter Furnace Maintenance Tips

Scheduling pre-season maintenance is always advisable. Enlisting a professional to clean and inspect your furnace after a long period of not being used can better ensure its reliability and efficiency throughout the winter months.

Tip #1: Hire a trained professional to conduct an annual maintenance service during autumn.

Here are other quick furnace maintenance tips you can do yourself. Remember, nothing beats regular maintenance. However, these are things you can do if you are already gasping for warm air.

Quick view of maintenance tips:

  1. Schedule yearly furnace maintenance before winter.
  2. Inspect and clean your filters.
  3. Check the state of your burners.
  4. Remove any obstructions near vents.
  5. Clean your pilot light assembly before primary re-ignition.
  6. Replace corroded or rusty fan blades.
  7. Check the manufacturer’s specifications in case of system failure.
  8. Report unusual noises. 
  9. Familiarize yourself with your thermostat.
  10. Keep up with routine professional maintenance.

Furnace Filter

Tip #2: Check your furnace filter system.

A dirty furnace filter can hinder your heating system, costing more energy while providing insufficient warmth. Many homeowners with natural gas furnaces think they save on energy costs, but that is only part of the truth. If you don’t maintain your gas furnace, distributing heating around air ducts can cost more energy.

Your furnace’s filter plays a major role in the entire operation. While filters cannot directly better air quality, your furnace’s air filters protect internal components from dust and debris. Any particle pollution and contamination pose different obstructions and hazards to internal components. A clogged air filter can restrict airflow, preventing sufficient input from making it where it needs to be.

Your furnace’s air filter can affect the one in your HVAC system or air ducts once dust and debris make it past the primary air filter into heating vents blowing air into your living spaces, directly affecting your indoor air quality.

If you see a dirty filter in your furnace after months of no usage, clean it to ensure only pristine air flow through your air ducts. However, only some dirty or clogged filters can be remedied by thoroughly cleaning. Change your furnace filter every few months.


Tip #3: Check your burners.

Furnace maintenance requires a thorough cleaning, and it isn’t just filters that get dirty. While filters help prevent pollution from contaminating your furnace, residual fuel and burner moisture can cause corrosion.

Burners and blowers may not be accessible from the outside, and you will have to open up your furnace to inspect them. Ensure all systems are off and any links to supply lines before opening furnace doors to check on internal components. A sophisticated configuration of internal components comprises your home furnace. The most vital parts lay in your burners:

  • heat exchangers
  • pilot light
  • flame sensor
  • ventilation

Each element plays a unique role that’s crucial to keep your furnace working properly.

Heat Exchangers

The heat exchanger facilitates airflow in and out of your furnace, letting usable air into the furnace and keeping breathable output separate from contaminated air. Heat exchangers dispel waste heat into chimney-type vents and direct breathable hot air into your air handlers.

Tip #4: Remove obstructions and use a vacuum cleaner around all openings; blocked vents may redirect carbon monoxide fumes into your AC system.

Pilot Light

A low, light yellow or flickering flame indicates dirty furnace burners. If the pilot light doesn’t turn on, don’t be too quick to blame it on a sensitive or faulty flame sensor. Delayed ignition may be due to internal contamination or residue and condensation.

Tip #5: Gently dust off debris with an emery cloth, and wipe off any residue on your pilot light assembly using light grit sandpaper. 


Tip #6: Replace rusty fan blades, and wipe off or remove any dust and debris on your blower wheel.

Your burners let air flow through various vents to gather input and produce output. A blower system is responsible for allowing air in and out of your furnace. Natural gas furnaces also require air intake to generate any output. Insufficient air can result in an overheated furnace due to various pressure buildup, causing overcompensation and a possible surge in your utility bill.

Like burners, your blowers are more than just a one-person team. Various elements make up the entire furnace blower system. Keep an eye on these components and ensure they undergo routine maintenance, as any damage will warrant costly repairs.

Blower Motor

The heating season may throw your motor into overdrive. You must maintain the motor to keep everything else in working order. Always keep your furnace clean to secure your engines from dislodged parts and harmful particles. Anything that infiltrates them may get in the way of their wire connections. Your entire furnace may break down due to frayed wires. If you live in an area with rats, deploy extra precautions against rodents and pests.

Tip #7: Depending on manufacturer warranties, you might be able to replace a malfunctioning or damaged motor.

Blower Fan

The blower fan, the wheel it’s on, and its blades all directly affect one another. Solid debris, such as rocks, may be caught in your blower if your furnace produces unusual banging and rattling noises. Small stones and sharp objects may tear through the furnace filters into other components. The filter can only vet microparticles and soft larger ones. Winter requires more heating, causing fans to rotate much faster.

Tip #8: Remember that you may attribute a few unusual noises to more vigorous fan rotation, but the higher demand for heating shouldn’t warrant alarming noises.


Tip #9: Always familiarize yourself with manufacturer specifications before setting your thermostat.

A cooling or heating system comes with a separate thermostat. Thermal controls allow quick temperature alterations. However, a thermostat may not quickly shift from cooling to heating at a moment’s notice. There are also possible issues with compatibility with your thermostat and HVAC system. You might need to replace the unit or fix its internal wiring if your HVAC equipment stops responding to thermostat controls. No predictable or universal lifespan guarantees your thermostat. However, with its systems included in your yearly maintenance, it should last a decade.

The Importance of Maintaining Your Heating System

The most important tip of all our furnace maintenance and tune-up tips, especially before winter months, is to ensure regular inspection and comprehensive maintenance. Things that start with your filter that isn’t dealt with in time may keep you from your dreams of a cozy winter. Comfort isn’t the only thing a dirty furnace can negatively impact. Your faulty furnace can also put your health and safety at risk.

How Your HVAC System Can Affect Your Health?

Something as simple as bird nests resting on exit pipes and heating vents can threaten your health. Nests blocking intake pipes may contaminate the resources going into your furnace. However, anything blocking your exhaust pipes traps contamination within your furnace, impacting your Indoor Air Quality (IAQ).

Indoor Air Quality

A lot of us know about IAQ but continue to neglect the different dangers it poses to our health. Your home’s IAQ is determined by the presence of Carbon Dioxide in your indoor environment. A buildup of CO2 can lead to chronic and acute respiratory illnesses. However, it isn’t your home’s most dangerous chemical gaseous compound. Carbon monoxide exposure is more harmful and potentially fatal compared to CO2 buildup.

While you can still let carbon dioxide out through natural and mechanical ventilation systems, carbon monoxide poisoning happens much more quickly. Even more problematic is carbon dioxide smells like rotten eggs, allowing homeowners to pick up on it faster than its more hazardous counterpart.

Carbon monoxide doesn’t smell like anything and stagnates anywhere with static pressure. You won’t be able to get rid of it as fast as it can build up. Call for emergency heating repair immediately.

Furnace Maintenance & Repair

Tip #10: Don’t hesitate to call professionals for help. 

A furnace is a sophisticated system. It requires professional tools and techniques. Using amateur tools and techniques, you might cause more damage by conducting haphazard repairs. If you have been duped by unreliable services before, remember that there are transparent and honest HVAC technicians you can entrust with your heating system.

Why is my Air Conditioner making a Weird Noise?

It is typical for an air conditioning unit to make noise. However, unusually loud or weird noises may be a cause for concern.

An air conditioner making noise may not just be business as usual and requires your attention as soon as possible.

Don’t wait around for things to get worse. Something as simple as a dirty air filter can domino into something worse and require more time, energy, and money to rectify.

In Utah, where it’s often dryer and hotter, air conditioners have more difficulty keeping up. The harder it is for your air conditioner to meet your thermostat’s standards, the more each component kicks its cogs into high gear.

While some indicate difficulties, it isn’t always time to call an AC technician. Some sounds only indicate your air conditioner’s hard work in satisfying your needs.

What Are The Most Common Air Conditioner Noises?

If your air conditioner is making noise, don’t panic. There’s no need just to jump the gun and call a professional.

Air conditioning units make noise all the time, especially under intense Utahn heat. The harder your AC unit works, the louder it gets.

Don’t Worry About It

A subtle humming noise or the typical AC clicking noise we hear isn’t necessarily disconcerting.

You can expect this from your cooling system when you set the thermostat to its lowest possible setting during a day that’s hotter than usual.

Set It and Forget It

These types of sounds you can bypass without worrying. They may also die down after successfully lowering indoor temperatures.


These noises aren’t the ones you should be on the lookout for, as they won’t be detrimental to your unit.

However, there are you must call in.

When to Worry About a Noisy Air Conditioner?

Subtle noises that go away after a little while aren’t a threat, but that high-pitched squealing noise your AC unit is making might be.

When typical AC noises become loud buzzing noises or other strange noises, it’s time to call a professional. Don’t underestimate any unusual noise your air conditioner makes.

An electrical problem may be on the horizon, and it might cost you more than a pretty penny.

A Cause for Concern

Strange noises may lead to harmful and costly hazards. Don’t attempt to investigate or remedy things by yourself.

Air conditioner noises might stem from poorly maintained electrical components and other issues from improper installation.

At best, loose wiring can damage your air conditioning system beyond repair. At its worst, it may cause you serious bodily injury.

Still, you should know a little about what may be causing the air conditioning noises you’re hearing.

What Causes a Noisy Air Conditioning Unit?

There are many potential reasons behind a loud air conditioner. An AC making noise is one of the best indicators of underlying problems.

Suppose you were to listen intently, especially where the noise is coming from, you might be able to call in a specialist for a specific problem and bypass the initial inspection and its relevant fees.

Quick Fix

A simple routine cleaning may rectify some issues, while some require dismantling and repairs. Loose parts and refrigerant leaks, for example, necessitate a certain set of expertise and materials to sort out.

If you correctly discern the noise, you might be better able to specify the issues you are having with your unit. When you establish your concerns, you can save more time and resources in correcting them.

Tight Fix

If you wait until Sandy’s cooling season from June to September to have your unit checked out, you will corner yourself into a tight fix.

You shouldn’t wait for the hottest days of the year anywhere in America to inspect and maintain your air conditioner. You risk a dog day summer if your air conditioner gives out and fails to cool your indoor space.

Call a Professional When You Hear These Unusual Noises

Let’s talk about certain noises, their potential causes, and what they may entail for your air conditioner.

Loud Noises

Call it in if it becomes too loud or overbearing, whatever the noise may be. The heat might not be the only thing sending your AC unit into overdrive.

Some of its components might be overcompensating for another or might be having a more challenging time keeping up. Understandably the harder it tries, the louder it gets doing so.

It’s time to come clean

A dirty air filter that isn’t dealt with correctly will only get dirtier, making it harder for air circulation, and causing louder noises. It shouldn’t cost you too much time or energy to remedy if it’s as simple as getting your air filter cleaned out or replaced.

Try to figure out what these noises sound like before you phone your local AC repairman.

Squealing Noise

If you hear loud noises that sound like a high-pitched squealing noise, you might be dealing with issues related to your AC unit’s outdoor fan motor or indoor blower motors.

A fan motor helms operations among its duties and is the most susceptible to burning out.

A fan motor and other more significant elements comprise your outdoor unit, otherwise called a condenser.

Fan Motors

The condenser fan motor transmits power to fan blades, which manage the air exchange outdoors and indoors.

The noise your air conditioner is making might be due to a worn-out fan motor having trouble powering your outside unit. Listen closer to your indoor unit if the AC noise isn’t coming from the outdoor condenser unit.

If both your indoor and outdoor AC unit are projecting a squealing noise, something is likely disrupting its transmission.

When you call a professional, let them know you might be having issues with your fan motor so they can bring the necessary equipment for its repair and maintenance.

Banging Noise

Loose parts from a blower motor or fan belt might be louder than small parts clanking around the unit.

The banging noise will most likely come from your outside unit. It might be louder than a rattling noise or clanking noise which indicates loose screws or diminutive particles getting caught in its motors.

Its condenser fan blades garner energy from outdoor fan motors to gather outdoor air for filtering and conditioning before passing it onto its indoor components.

Issues may also stem from your indoor blower fan. The indoor blower fan is responsible for releasing air indoors and making more noise when dislodged.

If you hear a rattling noise, the blower fan belt might be dealing with loose fan blades, or another loose or broken part may have gotten caught within its blades.

Its rattling is due to different components being hit and moved around by its motions. Issues with your fan belt include it slipping out of place and causing a rattling noise. Technicians can quickly remedy it by dismantling the unit and reattaching it to its proper place.

If the entire unit is jumping in its place, producing a banging noise, turn it off immediately. Don’t attempt to touch, dismantle, or inspect the unit if you aren’t a licensed technician.

Screeching Noise / Hissing Noise

We typically mistake one for the other, but anything that sounds like air pressure released at a higher pitch is typically due to built-up pressure.

Anytime your compressor carries high internal pressure, it will find avenues for its release. It isn’t always concerning as it will carry out the release on its own and what you are hearing is its process.

However, the screeching noise or hissing sound should only last between ten to fifteen seconds. A screeching noise that lasts any longer might be a problem.

Listen for a hissing noise from the inside or outside AC unit. If the hissing noise persists in a sustained fashion or on and off, it might be prime time for your outdoor unit to get its routine decompression.

If your AC system is congested with enough high-pressure air to produce a prolonged hissing noise, it may hinder its internal operations. The air pressure contained within the unit may be high enough to dislodge components and disrupt airflow.

Pulsating Noise

A rhythmic pulsating noise may be due to improper or insufficient insulation. Buzzing noises may accompany the pulsating noise.

The functions that comprise a heating and cooling system include various operations. Its intensity can result in vibrations. They may resonate within the unit and be heard on the outside without sufficient insulation.

An air conditioning system requires insulation for managing air pressure and overall stability. Its improper installation, flimsy connections, and long-term UV exposure can damage its insulation.

The HVAC system has various lines connecting each component with the other. When they falter under the typical pressures air conditioners face, they project a pulsating noise that only gets louder over time.

You need to call an HVAC technician immediately when you hear this noise.

Buzzing Noise

A buzzing noise is alarming and rightfully so, as it might involve issues with its segments that conduct electricity.

If you hear a buzzing sound, check if it’s coming from your outdoor unit or not.

If it’s coming from your condenser, the issues might be related to its fan motors. When the condenser fan motors continue to power fan blades that are stuck or have loose parts hindering their movement, a loud buzzing accompanied by violent vibrations will be evident.

If it involves loose parts, copper lines inside your indoor unit rubbing against panels and other wires might be the issue.

An AC noise you can hear from your indoor air conditioner can also be due to frozen components.

Yes, an air conditioner is built to manage contrasting temperatures. Still, without proper maintenance, contaminants and mismanaged air pressure can freeze or char its processors.

Buzzing noises are typical indications of frozen segments within the AC system, especially when there’s a refrigerant leak somewhere.

Clicking Noise

A clicking noise is typical in every air conditioner starting up and shutting down. However, constant clicking isn’t regular.

You can investigate further if clicking persists through its entire cooling cycle. Listen intently for intervals in time and volume.

Issues can either be with its fan blades getting bent out of shape and improperly relaying transmission. It’s an issue that isn’t typical for an air conditioning unit installed correctly.

Don’t wait for these problems to come around. Ensure you only entrust all installations, repairs, and maintenance to a reliable technician.

Faulty installations can lead to grave problems down the line and cost you immensely.

Bubbling Noise

A bubbling noise that might sometimes mimic a whistling sound is often due to a refrigerant leak.

If there is a refrigerant leak, there’s no way you can or should manage that on your own. Any abrasions in coils and compartments can disrupt its entire circulation process.

Even pinholes are enough to cause air leaks and refrigerant leaks. An air conditioner emits bubbling sounds when refrigerant fluid flows or collects in areas it shouldn’t.

When you phone your concerns to a local repairman, chances are they will tell you to call a licensed expert. Not only do these things require a particular set of expertise, but they will call for replacement parts and equipment only specialists carry.

Grinding Noise

It can begin with a humming sound, which may be non-threatening. However, if you listen closely, it might be subtle grinding noises.

It will get louder over time and become incessant as it gets worse. One loose part can domino into more, and the more materials knocking around inside, the harsher the grinding gets.

Parts of your AC coming loose come as no surprise. All the processing it takes to cool spaces in areas as hot as Utah will result in faster wear and tear, especially with older air conditioners.

You must keep up with routine checks and maintenance.

A Guide to Understanding Thermostat Settings

If your home has a centralized air conditioning system, then you have a thermostat that helps you control the temperature settings. Unless your system is extremely old, it’s likely that the system has a programmable thermostat with multiple settings. Understanding what each one of these settings does helps you to optimize them to enhance your energy savings throughout the summer months.


The one thermostat setting that most people are familiar with is the temperature. This is simply the setting for the temperature that you want in your home. For example, if you want your home to be 78 degrees, you’ll set the temperature on your thermostat to 78 degrees. Your air conditioning system will continue to use that degree marker whenever the system is turned on.

It’s important to note that your thermostat will also display the actual temperature inside of your home. At first, it can be easy to get these confused. However, once your system starts running, you’ll be able to notice that the actual temperature reading will decrease as the temperature inside of your home decreases.

Auto Mode

Auto mode is probably the most common thermostat setting that you’re going to be dealing with. With this setting, you will input your desired temperature into your thermostat. When the actual temperature in your home is above what your desired temperature is, auto mode will cause your air conditioning system to turn on. It will cycle through until the air inside of your home reaches the desired temperature. Then, auto mode will shut the system off until the actual temperature rises above the desired temperature again.

On Mode

Many people get auto mode and on mode confused. Unlike auto mode, on mode kicks your air conditioning system on, and it will continuously run. The desired temperature that you have set isn’t taken into account with on mode. Instead, it will just continue to run until you manually turn the system off. This setting should be reserved for specific times when you’re just looking to circulate air throughout your home. For example, if you’re opening some rooms that have stale air in them, turning your thermostat to on mode for an hour or so can help to circulate fresh air into all the areas of your home.

Run Mode

To get the most energy savings out of your home air conditioning system, it makes sense to program your thermostat around your daily schedule. It’s recommended to have your thermostat set at a comfortable temperature like 78 degrees while your family is at home. When your family is not going to be at home, it is possible to up the temperature to around 88 degrees. This will prevent your system from running when no one is home so you don’t have to waste any energy.

Try to plan and program your entire weekly schedule into your thermostat. This way, you don’t ever have to worry about messing with the settings unless something with your schedule changes. Once your thermostat is programmed at different temperatures throughout the day, it will go into what is known as run mode. Whenever you see the run setting, it simply means that your thermostat is running based on the desired temperatures that you programmed into it for various hours throughout the day.

Hold Mode

While programming your thermostat can do wonders for saving you money on your electricity bills, sometimes life throws you a curveball. Let’s say that one of your children is sick, and you end up spending a weekday at home with them. Your thermostat is programmed to increase to a high of 88 degrees during the day because you’re usually not at home.

To prevent this from happening, you can switch your thermostat to hold mode. This mode allows you to pause all the programmed settings in your thermostat so that you can set the desired temperature to what you want at that particular moment. In the scenario we went over above, you will be able to hit the hold mode and change the temperature to 78 degrees since you’ll be at home. As soon as you turn off the hold mode, your thermostat will resort back to the run mode that was programmed into it.


If you have a digital or a smart thermostat that includes a humidity setting, it’s crucial to understand what this setting can do for you. Humidity is presented as a percentage on your thermostat. For example, you may set your humidity at 30% to create a comfortable indoor environment for your family.

On very humid days outside, that humidity can seep inside of your home. The higher the humidity level in your home, the hotter it feels. While your thermostat setting is 78 degrees and your home is an actual temperature of 78 degrees, it still may be very uncomfortable if the humidity level is above percent relative humidity. Fortunately, you can use your humidity setting to ensure that your air conditioning system continues to run to remove the humidity from the air until the relative humidity level reaches the desired percentage that you’ve set.

Heat Cool Modes

Two very common thermostat settings are heat mode and cool mode. As you’ve likely guessed, you want to set your thermostat to heat mode when you want to warm your home, and you should set it to cool mode when you want to cool off your home. It’s important to remember to switch between these two settings in order to get the desired temperature that you’re looking for.

While you may be under the false assumption that your thermostat has to be on either the heat function or the cool function, that’s not actually correct. You can run your heating and cooling system simply with the on mode. This will recirculate the existing air throughout your home into the ductwork and back out through the supply vents.

Eco Setting

If you have a smart thermostat installed at your home, you likely have an eco setting. This may be labeled eco-friendly or be shown with a simple leaf symbol. When this setting is turned on, your smart thermostat will alter the temperature in your home based on what is the most energy efficient. New smart thermostats use your smartphone’s location to determine when you’re home and when you’re not. It will adjust the temperature based on your location to ensure that your house stays nice and cool when you’re at home.

How to Connect your New Thermostat to your AC

Whether you’re replacing a broken thermostat or upgrading to a new model, it’s important to understand how your new thermostat works. A smart thermostat can tailor the temperature in your home to fluctuate based on your day-to-day needs. Your air conditioner will only run when you program it to. You can program it to cool the house before you get home or raise it when you’re sleeping. Depending on the device, you can also set it to detect your movement and adjust the temperature based on which rooms are in use. With a smart thermostat, you can even enhance the system’s efficiency and boost the comfort of your household.

Given the wide range of programmable devices available, determining the ideal setup for your property can be confusing. There are many features to consider, and you need to have a clear understanding of what each one does. The technicians at One Stop Heating and Air Conditioning in Sandy, UT, are available to help with any questions or issues you have with your AC system. Our qualified and experienced technicians have the skills to install, diagnose, and optimize your unit. Let’s take a look at a few things you need to know to take full advantage of your new thermostat.

Why You Need a Smart Thermostat

Programmable thermostats are frequently referred to as smart thermostats. Different types of smart thermostats have varying capacities to tailor settings to your needs. We can help you to determine which thermostat will work based on the specs of the device and your preferences and requirements.

There are several ways a programmable thermostat can enhance the performance of your system, including:

  • Reduce energy consumption
  • Enhance comfort
  • Enable zone climate control
  • Connect to weather forecasts

Automatically Adjust Temperature

Depending on the number of times per day you typically change the temperature in your home, you may benefit from learning the features of your smart thermostat. Some devices can automatically change the temperature based on the time of day and the day of the week. This can be particularly helpful if there’s frequently no one home during the weekdays.

To further increase the efficiency of your AC unit, with some smart thermostats, you can divide the house into zones and have separate temperature controls for each zone. For a household with kids, having that level of precise temperature regulation can dramatically reduce the energy bills. Since the thermostat automatically adjusts the temperature, the system can accomplish its task with minimal work on your part.

Many smart thermostats work based on how you program them. Others, however, can adjust the cooling based on sensors that detect when someone is actually in the room. A sensor-based thermostat system has temperature sensors in different rooms or zones. When a sensor detects that the room or zone is being used, it automatically adjusts the cooling to achieve the temperature set for that room. While this type of system requires a higher initial investment, it’s the most efficient technique to maximize energy conservation, which in turn lowers your energy bill.

Utilize New Technologies

The features of your smart thermostat can make temperature control more convenient. Many smart thermostats are Wi-Fi enabled to give you the ability to control the device from a smartphone or PC. You can check and make changes to your system even when you’re at the office, on the road, or on vacation.

Additionally, some modern devices can use weather data to make the necessary adjustments. By using online platforms, smart thermostats can inform the system when to anticipate fluctuations. It can use weather information to not only manage the cooling but also adjust to humidity changes. The approach ensures there’s little time for heat and moisture to accumulate. It anticipates the rise in temperature and adjusts to counteract this change. Your home will remain comfortable throughout the seasons.

System Compatibility

One issue you may have with a smart thermostat is compatibility with corresponding systems. For more advanced features like voice activation, the thermostat will connect to online applications. It’s important to analyze your existing system before you choose a new thermostat for your house.

Compatibility can also determine the equipment you’ll use. Some AC units, humidifiers, and dehumidifiers may fail to work through your smartphone or with a particular smart thermostat. If the device isn’t compatible with the equipment, it will be challenging to manage temperatures effectively.

You can talk to a professional from One Stop Heating and Air Conditioning to help you to choose and configure your thermostat. Our experienced professionals can assist you in developing the most optimal solution for your heating and cooling needs. We also offer air quality services and maintenance, repair, and installation of heating or cooling systems. Contact us today to learn more.

How To Save Energy Dollars in the Summer

When summer temperatures arrive, many people dread looking at their energy bills. Air conditioners can use a lot of energy and make it expensive to keep your home cool. There are several steps that you can take to reduce your summer energy bills and save money. Keeping hot air out of your house is important for both your comfort and your budget.

Keep the Sun Rays Out

Having the sun’s direct rays entering your home through windows is a quick way to have the air in your house heat up. When the sun is out, keeping your shades down or your curtains drawn can keep the direct rays from entering your residence. If you have any awnings on your home, keeping them out can further block the sun. Raising shades when it’s cool out can allow hot air to escape from your house.

Install a Smart Thermostat

If you don’t want to come back to a hot house after work but don’t want to run your air conditioner all day, a smart thermostat could be a great solution. These units can be programmed to keep your property at certain temperatures at different times of the day. You can set your unit to have your house at the right temperature whenever you come home from work. With the advanced technology of these thermostats, they’ll be able to cool your home in a highly energy-efficient manner. When you leave your house, they’ll automatically turn off so that your air conditioner isn’t running when there’s no one home.

Increase Your Home’s Insulation

The insulation in your residence doesn’t just keep warm air in during the winter months, it can also keep hot air out during the summer. Adding extra insulation to the roof and attic areas of your home can be a very cost-effective way to lower your summer cooling bills. A lot of heat can also come into your residence through the glass of your windows. Having double-pane windows installed can effectively keep the heat out.

Schedule an Energy Audit

An energy audit can show you where your home is losing energy. Cool air can escape from your house through small cracks around the exterior doors and windows of your property. A technician can perform a blower test to see where these leaks exist and give you options for getting them replaced. They’ll also be able to show you various other places in your home where you can reduce your energy use.

Install Energy-Efficient Appliances

Having a highly energy-efficient air conditioner is one of the best ways to minimize your summer cooling bills. Modern units can cool a large area while not using a lot of energy. If your unit is properly sized for your home, it will have the power to cool evenly throughout the various rooms of your house without wasting any extra energy. Air conditioners have energy-efficiency ratings so that you can calculate the savings that each individual unit could provide in your home. Efficient units could end up being a great investment in your property.
