Furnace Repair Company Castle Rock

A Guide to How Furnace Repair is Carried Out Today

Furnace repair is simply fixing the furnace when it breaks down. While most of the time it may be a small issue, sometimes it can become worse and lead to something disastrous. A common question we get is how is furnace repair carried out? Let’s find out in this post.

Furnace Inspection & Diagnosis

With the help of a furnace inspection checklist, the furnace technician will examine the furnace to find out why it has stopped working. They will also run some tests on the furnace to find the problem, such as a thermal test, pressure test, and functional test. Based on the findings, they will also determine the cause of the problem.

Runs the Furnace Issues by You

Next, on the furnace repair checklist, the technician will discuss the issue with you and give his opinion of the problem. After this, they will then discuss the same with you and let you know about the probable cost of the repair work.

Furnace Repairs

The technician will fix the issue and will check if any other parts or components are also damaged. In case a part is broken or damaged beyond repair, they will replace the damaged component.

He will also go through the furnace warranty and will check if any parts or components need to be replaced.

Final Checks & Tests

The technician will then run a final test on the furnace and will check if everything is working fine. They will also make sure that the heating system is working perfectly without any issues.

If the furnace has any other problems, the technician will take care of them or ask you to contact the manufacturer or the supplier directly. They will also give you some basic tips on solving the problem yourself and ensure that the furnace continues to work in the best possible manner.

Warranty on Furnaces

The technician will also discuss with you the warranty of the furnace and at the disposal of old parts, if any. The furnace technicians follow strict rules and guidelines during an inspection and diagnosis. This ensures that you have a valid warranty and get the best service possible. The technician will also inform you about any warranty issues and will advise you about what to do in case of a warranty issue. The technician will also inform you about any other upcoming maintenance work that you may need for your furnace.

How to Find The Right Furnace Repair Company

If you want to find the right furnace repair company, you must consider a few things. First, you need to ensure that the company is certified and experienced. This will ensure they have the right set of knowledge and skills to carry out the furnace repair work. Next, you also need to find a trustworthy furnace repair company. If they have a good reputation, they are more likely to do a good job. If the reviews are good, you will also know you have found a good company to hire.

The Bottomline on Furnace Repair

The steps mentioned above are the most important steps for furnace repair. Hiring a skilled technician is the most important thing to ensure that your furnace is working properly.

Air Conditioner Is Blowing Hot Air

Common Reasons Why Your Air Conditioner Is Blowing Hot Air

It’s horrifying to have an air conditioner only to have it blow hot air. This can be especially annoying if your location is currently experiencing hot weather. Now, why exactly is your air conditioner blowing hot air? In this article, we discuss possible common reasons why this may be occurring.

Why Is Hot Air Coming Out of My Air Conditioner?

If you notice hot air coming out of your air conditioner, there could be a few different reasons why. Below are some possible explanations as to why you may be experiencing this.

1. Low Refrigerant Levels

Hot air might be coming out of your AC unit because the refrigerant levels are low. When the refrigerant levels are low, the AC unit cannot cool the air properly, which can cause the air to come out hot. If you think this might be the problem, it’s important to have a professional come out and check the levels, as it’s not something you should try to fix on your own.

2. Frozen Evaporator Coil

Another reason for hot air coming out of your AC unit could be the frozen evaporator coil. This can happen if the air conditioner is not getting enough airflow, which a dirty air filter can cause. If the evaporator coil is frozen, it will not be able to absorb the heat from the air properly, causing the air to come out hot. Again, this is something that should be checked by a professional.

3. Dirty Air Filter

A dirty air filter is one of the most common causes of hot air coming out of your air conditioner. When your air filter is dirty, it restricts the flow of air to your air conditioner, causing it to work harder to cool your home. As a result, your air conditioner will produce hot air instead of cold air. To fix this problem, simply replace your dirty air filter with a new one.

4. Faulty Compressor

A faulty compressor can also cause hot air. When your compressor is not working properly, it prevents your air conditioner from circulating refrigerant, causing it to produce hot air instead of cold air. If your compressor is not working properly, you’ll need to have it repaired or replaced.

5. Overworked Air Conditioner

Your air conditioner is overworked. This can happen if you’ve been using it a lot or if the weather has been particularly hot. If this is the case, you may just need to give your air conditioner a break for a few hours.

6. Not Set Properly

Finally, hot air could come out of your AC unit simply because it is not turned on low enough. If the AC unit is not set to low enough, it will not be able to properly cool the air, causing the air to come out hot. This is an easy fix – simply turn the AC unit down to a lower setting and see if that helps.

Conclusion on Why Your Air Conditioner is Blowing Hot Air

There are a few reasons why hot air might come from your air conditioner. It could be that the unit is low on refrigerant, the air filter is dirty, or the compressor is failing. If the problem persists, it’s best to call a certified technician to come to take a look.

Heat Pump Maintenance

All You Need to Know About Heat Pump Maintenance

A heat pump is an efficient device regulating the temperature in a space by moving heat from one area to another. Heat pumps can be used in warm and cold weather, making them a versatile option for climate control. In order to keep your heat pump running correctly, it is crucial to do some essential maintenance on the unit throughout the year.

Need help with heat pump maintenance? Have questions about installing a heat pump system? The CG Heating & Cooling team is the expert in all things heating and cooling in Westminster, CO, and nearby areas. In this post, we’ll cover what you need to know about heat pump maintenance:

How Heat Pumps Work

Heat pumps are powered by electricity and use refrigerant to transfer heat. The refrigerant is a fluid changing from a gas to a liquid and back again as it absorbs and releases heat.

The refrigerant is circulated throughout the heat pump by a compressor. The compressor increases the pressure of the refrigerant, which causes it to absorb more heat. The refrigerant is then passed through a condenser, where it releases the heat.

The refrigerant then goes through an expansion valve, reducing its pressure. This causes the refrigerant to cool, absorbing heat from the surroundings. The refrigerant is then passed back through the compressor, and the cycle starts over.

Heat Pump Maintenance Tips

If you want your heat pump to last for many years, it’s essential to keep up with regular maintenance. Here are several helpful tips that will keep your heat pump in top condition:

1. Check the air filter every month and replace it as needed. A dirty air filter can reduce the efficiency of your heat pump and put unnecessary strain on the system.

2. Have your heat pump serviced by a professional at least once a year. This will ensure that all the parts are working correctly and that there is no build-up of dirt and debris.

3. Keep the area surrounding your heat pump clear of debris and vegetation. This will help keep the system running smoothly and prevent potential damage.

4. Check the outdoor unit of your heat pump regularly for any signs of damage or wear. If you notice anything, contact a professional for repairs as soon as possible.

5. If you have an automatic defrost system, ensure it works properly. This system helps prevent the build-up of ice on the outdoor unit, reducing its efficiency.

Following these tips can help keep your heat pump in good condition and extend its lifespan.

What Is Included in Professional Heat Pump Maintenance

A professional heat pump maintenance service will typically include a thorough inspection of your unit. The technician will thoroughly check all the moving parts to ensure they are in good working condition. They will also inspect the electrical components and the refrigerant levels.

In addition to the inspection, the technician will also clean the heat pump. This will remove any dirt or debris that could potentially cause problems. They will also lubricate all the moving parts of the heat pump to ensure they operate smoothly.

After the inspection and cleaning are complete, the technician will test the heat pump to ensure it is operating correctly. They will also make necessary adjustments to ensure it runs as efficiently as possible.

Conclusion on Heat Pump Maintenance

As a homeowner, you must understand that routine maintenance is important to keep your home in top condition. The same is true for your heat pump. A well-maintained heat pump will operate more efficiently, use less energy, and last longer than one that is not properly maintained.

By getting heat pump maintenance and repair when needed, you can be sure your heat pump will continue to operate efficiently and last for many years to come.

Furnace Maintenance for Homeowners

The Average Homeowner’s Guide to Furnace Maintenance Part 1

Your furnace is one of the most important parts of your home, so it’s important to keep it running smoothly. You don’t need to be an expert to do this—there are many simple things you can do to help.

Even if you’re unfamiliar with how furnaces work or what’s behind the doors, there are easy ways to keep them running properly. Some simple steps can help ensure your furnace stays in good condition and doesn’t break down when you need it most.

Part 1 of this blog will focus on four furnace maintenance tips that even the average homeowner can do. Here are some ways you can keep your furnace operating at peak efficiency:

1. Change Your Air Filter

One of the best ways to keep your heating and cooling system running efficiently is to change your furnace filter regularly. A dirty air filter can block airflow through your heating system, making it harder for the fans in your blower unit to move the air needed to heat your home.

Filters are important for keeping your home’s air clean. They remove dirt, dust, mold, and allergens from the air. Over time, filters get dirty and lose their effectiveness. It’s important to replace dirty filters with new ones to keep your home’s air clean.

If you want cleaner air to breathe, high-quality filters are a great way to get it. Whether you have pets or live in an area with a lot of pollen, dust, or other airborne pollutants, filters can make a big difference in the air you breathe.

2. Clean Around and Inside Your Furnace

It’s important to keep the area around your furnace clean so that the inside of the furnace doesn’t get dusty and dirty. Regular sweeping and vacuuming will help keep the inside of the furnace clean. Make sure to store any chemicals or cleaners away from your furnace, as they can spread throughout your home.

You can complete the task of cleaning the blower motor and fan of your furnace if you are feeling up to it. Before removing the panel that accesses the blower, be sure that the circuit breaker to the furnace is turned off and the gas is shut off. Once you have access to the blower, use a shop vac and an extension hose to clean it.

You shouldn’t worry about handing this job over to a professional. They will take care of inspecting and cleaning the furnace during their regularly scheduled visits.

3. Keep Vents Clean

Duct cleaning is the process of removing debris and dirt from the ventilation system in a home. This is usually done every few years, especially if the home is older or if there are pets in the house. Duct cleaning can remove dust and dander and check for leaks or mold buildup. You should clean your air vents yearly to remove dirt and dust. This will improve your indoor air quality.

4. Keep Your Ears Open

If you hear strange noises from your furnace, it could signify something is wrong. If something doesn’t sound right, it’s often a good indicator of a problem. Unusual noises can be a sign that there may be a serious problem developing in your furnace.

If you hear strange noises from your car, it’s best to get professional help immediately. These noises could signal something is wrong with your car, so it’s best to check it out before it becomes a bigger problem.

Conclusion on Furnace Maintenance for Homeowners

It is important to remember that furnace maintenance is not a one-time event. Just as you would not only change the oil in your car once and expect it to run perfectly for the rest of its life, you cannot simply change your furnace filter once and expect your furnace to run perfectly forever. Regular maintenance, including changing your furnace filter regularly, is necessary to keep your furnace running efficiently and safely. Read on to Part 2 of this blog for more furnace maintenance tips.

Common air conditioner sounds

What Are Air Conditioner Sounds That You Need to Beware Of

The low hum of an air conditioner is a sign of warmer weather and the opportunity to enjoy cool air on a hot, humid day. An air conditioner has a lot of different parts that all work together to keep it running. The age of the unit and how often it’s used can affect how well it works. This is the reason your AC unit is making strange noises, it could be a sign that it needs to be repaired.

What are specific air conditioner sounds you need to know? Keep reading below.


If your AC unit is making loud banging noises, turn off the power to the unit immediately. The compressor may be causing the noise. If the unit is allowed to continue making noise, you may need to replace the entire unit.

Bubbling or Gurgling

If you hear a bubbling or gurgling noise coming from your air conditioner, it could be a sign of a refrigerant leak. Refrigerants can be harmful to your health if you’re exposed to them, so it’s important to call a repair service if you think there might be a leak. A drop in refrigerant can also damage your air conditioner, so it’s best to get it checked out as soon as possible.


In short, if your air conditioner starts making a buzzing noise, it’s time to call a maintenance specialist. It could be a simple problem like a frozen line, but it could also be something more serious like frayed electrical wiring.


A rattling noise produced by your air conditioner could be a cause for concern, and you should have a professional take a look at it as soon as possible to determine the root of the problem.

Running Water

The sound of running water coming from your air conditioner could mean that there is a problem with the drain line. This could be because the line is split or broken, which can cause damage to the unit and the surrounding area. If you hear this noise, you should call a professional technician to have the problem repaired.


If your air conditioner starts making a loud screeching noise, it may mean that the belt or fan is beginning to wear down. If the noise stops when the unit is running at full capacity, the issue may be with the compressor. Either way, it’s best to call a professional repair service.


If your air conditioner starts making a deafening humming noise that sometimes sounds like a tea kettle whistling, it may mean that there’s a loose seal somewhere in the AC. Other possible causes include a loose fan belt, worn-out bearing, or internal pressure buildup. In some cases, the whistling noise may also be caused by a motor that needs to be lubricated, or it may be the first sign that the compressor is starting to fail. If you hear your AC making a whistling noise, it’s a good idea to have it serviced as soon as possible.


There are several air conditioner sounds to beware of. If your air conditioner is making any of the mentioned sounds above, it could be a sign of a severe problem. If you suspect your air conditioner is in need of repair, be sure to contact a qualified technician as soon as possible.

Air Duct Odors hvac duct cleaning

Air Duct Odors: What the Smell Reveals About Your Air Duct’s Health

If you’re not particularly familiar with the inner workings of your HVAC system, it might surprise you to learn that the air ducts can be a major source of different smells, as they’re the source of the airflow that brings the fresh air into your home. Depending on the issue, the smells can be anything from unpleasant to downright toxic.

If you’re not used to thinking about the air ducts as an integral part of a functioning HVAC system, you probably don’t realize just how easy it is for mold growth to start. Dust and debris build up on the inside of the air ducts, as well as on the coils of the air conditioning system. Over time, this causes the HVAC system to break down and stop working as well as it should.

If you started to smell something funny coming from the ducts of your vents, it’s probably time to call your HVAC company. But even with an expert just one call away, it helps to know what trouble these foul smells bring once you take a whiff off them from your air ducts.

Different Smells from Your Air Ducts: What Do They Mean?

Moldy and Musty Smell

A moldy or musty smell from your air ducts usually means that you have some type of mold growing in the ducts, or on the coils of your air conditioning unit. This can soon lead to serious health problems, including allergic reactions, asthma, and lung disease. It also clogs your air conditioning ducts and makes it hard for the air conditioner to keep the air in your house cool.

Burning Gas Smell

A burning gas smell from your air ducts usually means that there’s a bit of a sulfur-like smell and that your furnace is leaking gas. If you notice this smell, you should contact your HVAC company immediately, as the gas leak can cause toxic fumes to accumulate in your house and spread throughout your property.

Rotten Egg Smell

A rotten egg smell that comes from your air ducts usually means that there’s a gas leak. It can also be caused by your air conditioning unit or furnace not functioning properly, as these appliances use natural gas or propane to function.

Oily Smell

An oily smell that comes from your air ducts can be caused by a number of different issues, including the problem with the heating system or a vent that’s improperly connected. It’s also possible that there is a leak coming from the furnace coils, since the oils that are used for lubrication in the heating system leak out.

Electrical Smell

A burning smell that comes from the air ducts can be a sign of electrical problems in the vents. The smell will typically be accompanied by the strange smell of burnt wire. If you notice this smell, immediately contact your HVAC company, as the air ducts can become electrified and cause a serious fire.

The Bottom Line: Diagnosing Your Air Duct’s Condition Based on its Smells

If you ever find yourself noticing a strange smell coming from your air ducts, the best thing that you can do is to simply call up your air conditioning contractor, like CG Heating & Cooling.

Many times, the odor from your air ducts is a result of poor air duct maintenance or a general buildup of dust and debris. When you can’t tell the source of the odor, it’s best to have your air ducts cleaned by a licensed and experienced HVAC technician.

aux heat for home

Do You Need AC Repair for Auxiliary Heat Notifications

When winter is in full swing, you’ll be relying on your heat pump to keep you warm all season long. However, the time will come when you’ll notice an AUX heat icon displayed on your thermostat screen, which might be odd, especially if you’ve never seen it before. Should you call AC repair or just let it go away? Read on to find out about this nagging problem.

The Meaning of AUX Heat

Auxiliary heat and emergency heat are two separate modes for activating an electric resistance heating element.

  • The electric resistance heating (AUX) element is found in some HVAC systems. Both these modes slightly differ from system to system, based on the model of the heat pump system.

For instance, some systems only have an auxiliary heat mode, but others also offer an additional emergency heat feature. The supplemental heat aids the heat pump system in reaching the set temperature. Since this is the same way they are programmed in different models, people may say they turned auxiliary heat on or off even though they were using emergency heat.

AUX heat is also turned on by the HVAC system automatically.

  • Like AUX heat, emergency heat is a setting that activates the electric resistance heating strips to warm your home during the winter. The HVAC unit’s emergency heat is turned on manually to be your primary way of heating your home when the heat pump system malfunctions.

In contrast to the AUX heat’s automatic function, users must manually turn this mode on and off. This makes emergency heat significantly less efficient than auxiliary heat, and so it should only be used when necessary.

Overusing either mode will require AC repair since the heating system will stop working.

What Triggers AUX Heat?

Only three scenarios automatically power on an HVAC system’s AUX mode:

  • Whenever temperatures are freezing.
  • When the thermostat goes up in temperature.
  • When the heat pump needs to defrost itself after a snowstorm.

Other internal problems that cause this malfunction include:

  • Heat pumps that don’t produce heat.
  • A fan motor that does not provide the necessary airflow to absorb or release heat.
  • Low refrigerant levels prevent heat transfer from the outdoor coil to the indoor coil.
  • A faulty compressor that does not transfer heat from the outdoor condenser to the indoor air handler.

These component breakdowns require immediate attention from AC repair services.

The Proper and Improper Times for AUX Heat to Work

If the auxiliary heating turns on simultaneously with the system’s initial power-up, it should only run until the HVAC system reaches the set temperature.

However, if the auxiliary heat runs every time you turn your heater on or runs longer than 30 minutes, or does not stop, contact an HVAC pro to have your system evaluated.

Remember, auxiliary heating is just an additional part of the heat pump system heating your home. While it is accepted for it to turn on in cold weather, you should note if it is operating for a prolonged period. Aside from a checkup, the device might need AC repair.

Stay Warm throughout the Winter Season

Auxiliary heat keeps your home warm in the winter or other cold seasons. If it’s running consistently, there may be a problem that needs a component or full-on AC repair. We know that heating and cooling are essential to every home, so get your systems checked now and then for a smooth running HVAC in your house.

Furnace Installation

The Advantages of Having a Furnace Installed in Your Home

The Advantages of Having a Furnace Installed in Your Home

No matter the reason, when the coldest of nights come, we must prepare ourselves for the potentially long and sleepless battle against the cold. As we know, the best way to fight the cold is by layering up on clothes and blankets. But even with all those layers, there are still some parts of our bodies that are bound to feel the chill. Nobody likes cold feet when they’re trying to sleep. If you’re one of those people who can’t stand the cold, it’s time to get a furnace in your home.

Below are just a few of their other benefits.

1. They Mitigate the Cold Temperature

A fireplace may be beautiful and inviting, but it can’t provide warmth to your entire home the way a heater can. If you have a heater, you can say goodbye to your cold feet and enjoy a warm night in your home. A furnace heats up the air in your house and sends it through ducts to different rooms.

There are a few different types of furnaces available on the market, so it’s important to do your research and find the one that’s best for your home.

2. They Are Definitely Affordable

Why are furnaces so popular in America? It’s because they are very affordable. You can install a new furnace for only $2000 to $3500. A boiler typically costs around $2500 to $4000, while getting a fireplace built costs anywhere around $2000 to $5500. In such a case, you’ll be able to save a lot with a furnace.

3. They Are Able to Remove the Contaminants in the Air

Furnaces today come with air humidification technology to improve air quality. This means that the furnace can remove contaminants from the air, making it a healthier environment for you to live in. When you smell something pleasant, it can immediately boost your mood and make you feel happy.

4. They Provide Comfort

When the temperature outside dips, you can count on your gas furnace to keep your home warm and comfortable. Gas furnaces circulate warm air by pulling in cool air from your home, heating it up, and then distributing the warm air throughout your home using a system of ducts. It’s like being hugged by a warm blanket!

5. They Are Safe to Use

As with any type of heating system, a furnace will require regular maintenance in order to operate at peak efficiency. This means having it serviced by a qualified technician on an annual basis. During this service, the technician will clean the furnace, inspect it for potential problems, and make necessary adjustments. That said, it is still the best way to heat your home if it is maintained properly.

6. They Are Efficient

A gas furnace not only provides warmth but also helps to save on energy costs. You can save a lot of money on your heating costs by using a furnace, which can reduce your costs by 50% to 70%. This can help you keep your bills under control.


Overall, there are several advantages to having a furnace installed in your home. A furnace can provide heat during the winter months when temperatures can be extremely cold. A furnace can also help improve your home’s air quality by circulating fresh air and removing dust and pollen from the air. Additionally, a furnace can help to reduce your energy bills by providing heat more efficiently than other heating methods.

If you are looking for a company that specializes in furnace installations in Highlands Ranch, look no further than our services here at CG Heating & Cooling. Our technicians are NATE & EPA Certified, and with over 20 years in business, we have the experience to handle all your Heating and Cooling needs.

common sounds ac unit makes

6 Common Sounds That an AC Unit Makes and Their Causes

6 Common Sounds That an AC Unit Makes and Their Causes

How can you tell if there is an issue with your air conditioning unit? When your AC makes certain sounds, it is a common indication that there is a problem. Now, different sounds may mean different things. Here are some sounds that an AC unit may make and their possible causes.

1. Buzzing

AC units create vacuum pressure by cycling gas through a condenser coil, which absorbs heat and cools the active ingredients inside the unit. These units are typically very quiet, but they can begin to buzz when they are working.

A buzzing AC unit results in various symptoms, depending on what part of the system is malfunctioning. Most commonly, a buzzing AC unit means that there is something wrong with the internal workings of the unit. More seriously, it could mean that the refrigerant has leaked out or the fan blades aren’t balanced correctly, both of which need immediate attention.

2. Banging

A banging sound from inside your air conditioning unit is most likely caused by a broken or disconnected part. It can be a moving part, such as a crankshaft, piston pin, connecting rod, or rotating fan blade inside the compressor unit. If one of these is broken or disconnected, then you must replace the compressor.

3. Clanking

If you hear loud noises from your AC, the coils in the unit have likely become unbalanced. This can happen if an internal component of the compressor breaks, usually requiring repairs and replacement.

If parts like the internal fan hit other internal components, the problem will only worsen and cause more damage. Not only will loose parts be damaged, but they’ll also knock other parts out.

4. Squealing

Indoor blower motors and outdoor fan motors begin to squeal when they’re failing. You should evaluate the sound’s tone, frequency, and duration to distinguish it from regular squealing.

5. Clicking

When the unit is turned off and then on again, it is normal to hear a clicking sound, but if the unit is turned on and the clicking starts or stops, it can be a sign of a thermostat problem. If the unit is on and the clicking is frequent or perpetual, it could be a sign of a control problem.

However, if you checked and confirmed that it isn’t a thermostat or control problem, it could be an electrical issue. Electrical issues can lead to more costly and even dangerous problems, so if you notice any frequent clicking sounds after turning your unit on, you should address the issue quickly.

6. Humming

Humming noises in air conditioning systems are often the result of loose refrigerant piping or some other parts. This can develop into a bigger problem if it goes ignored. Humming noises in air conditioning systems might also indicate electrical troubles. If there’s loose wiring or a malfunctioning compressor, humming is also likely to occur, and it needs to be investigated.


It is not wise to ignore unusual noises from your air conditioner because they may be signs that your unit has a problem. Ignoring the sound will increase the need for repairs in the future. To properly address the issue, you can have it inspected by a professional.

Does Your Filter Need Changing? 6 Replacement Tips

A well-designed, quality home HVAC air filter plays a crucial role in cleaning the air circulating to ensure pollutants and particles are trapped and removed from the air. A bad filter can negatively affect your heating and cooling system, health, and home. Read through some important questions people have about air filters and how to ensure they are performing as they should!

How Often Should I Replace My Furnace Filter?

It depends on its quality, how much air goes through it every day, how well you take care of it, and how many square feet it filters. The National Air Filter Association recommends changing your filter at least every three months to protect your system and your family’s health. However, you should replace filters more frequently if you are in an area where there are a lot of allergens or pollutants.

When Should I Replace my Furnace Filter?

If your filter needs to be changed, you can tell by looking at it. If there’s dust or dirt in your house, it could mean that you need to change your filter. Check the filter on your furnace often, especially if it’s in a busy area like the kitchen. It’s also a good idea to mark in your planner or calendar when you change the filter. If you own pets or have allergies, you might need to change your filter more often than NAFA suggests.

How Do I Know What Size to Get?

This is a very common question, and it’s an important one to consider when searching for the right furnace filter. Your filter should be at least as big as the area it covers, and it should be 3 to 5 inches bigger than that area. If you have a large-capacity air filter, you should check the filter’s surface area to make sure it is big enough to filter the amount of air going through it.

The most accurate way to find the right size is to measure it manually if you already lost its packaging. Find the extent that the filter is covering and compare it to the manufacturer’s recommendations for that product.

How Do I Know What Type of Filter I Need?

There are many different kinds and groups of filters, making it hard to choose the right one for your home. If you have some allergies or asthma, you might find that an electrostatic filter helps. These filters can cost more than regular filters because they are often made of synthetic fibers that attract allergens and other pollutants. More than 99 percent of particles 0.3 microns or bigger can’t get through standard HEPA filters, which are less expensive.

Do I Need to Get a New Filter Every Time I Get a New Furnace?

If you can change the filter yourself, you may not need to purchase a new filter every time you have a new furnace. However, if you aren’t able to change your filter yourself, you may need to get a new filter every time you get a new furnace. Be sure to ask your HVAC technician if the filter is compatible with your new furnace or if you need to purchase a new one.

How Do I Get My Furnace Filter Changed?

There are several ways to change the filter in your furnace. If you’re handy enough, you can do it yourself. If you don’t know how to change your filter, you can always call a contractor or HVAC expert. If you have your furnace serviced, the technician will change the filter if needed. You can also hire an HVAC company to change the filter for you. Numerous places offer maintenance or filter replacement to keep your system functioning smoothly.


The saying goes, “An ounce of prevention is worth a pound of cure.” When it comes to furnace filters, this is especially true. It’s straightforward to forget to change a furnace filter for too long. But if you take the time to change your filter regularly, you can improve the air quality in your home and save money at the same time!
