Steps To Change Your Air Filter
Changing the air filter in your HVAC system is an important and easy task, one you should be able to perform on your own. Here are the steps you need to take to change your air filter:
Air Handler Filter Replacement:
- Turn Off Your HVAC System: You don’t want your HVAC system running while there is no filter in place.
- Locate Your Filter: The filter is usually located by the air handler. It may also be behind a grate over your air return. If you have trouble locating the filter, consult your manual. You can also ask your HVAC technician during a routine maintenance. They can show you where it’s located and give you a tutorial on how to change it.
- Remove The Old Filter: You may have to take a small covering or case off first to access your air filter. Once you have the cover off, remove the air filter gently. It’s going to be full of dirt and debris, so you will want to have a trash bag ready to dispose of it right away.
- Insert The New Filter: The new filter should have little arrows showing you which direction it should be inserted. Once you put the new filter in, replace the cover.
- Turn On Your System: Now that the filter is secure and in place, it’s time to turn the system back on.
Return Vent Grille Filter Replacement:
If you have a return vent that has a filter behind it that needs to be replaced, this is also a simple swap.
- Remove The Grate: Remove the grate that the filter is hidden behind. If this is high up, be careful, and maybe make sure someone is there to assist you if you need to use a ladder. This grate usually has a hook that you pull and unlatch it, rather than needing to unscrew anything.
- Remove The Filter: Have a trash bag handy to throw out the dirty filter. Make sure you wipe away any excess dirt and debris left over, and clean off the grate as well.
- Replace The Filter: You can now place the new filter and secure the grate back on.
That’s it! It’s a simple task, but one that often goes forgotten.
As we mentioned above, if you are having trouble replacing your filter, ask your HVAC technician to show you during a routine maintenance. You should have your HVAC system serviced at least once a year, and during this visit, the technician will be able to show you how it’s done. They will show you where the filter is, and how to replace it.
Why Should You Replace Your Air Filter?
Replacing your air filter keeps the air in your home clean and also helps promote better airflow. The purpose of your filter is to catch any particles that may be floating in the air. Dust, allergens, bacteria, mold spores, and more are floating around the air, and with a dirty filter, it will fail to prevent them from passing through.
Over time, if the filter gets clogged, it’s going to create dirtier air, and also prevent your HVAC system from pumping air smoothly through your home. This backed-up airflow may cause different problems:
- Your system could short-cycle
- Your system may stop producing warm/cool air
- Your heat exchanger could crack in your furnace
- Your coil could freeze on your AC
- Your air will become dirtier and less healthy to breathe
- Your system may have to run harder, driving up your energy bills
For such an easy task to take care of, you can see the many benefits of replacing the air filter.
How Often Should You Replace Your Air Filter?
We recommend you replace the air filter once every 1-3 months. During the winter and summer, when your HVAC system is running constantly, and the windows are closed more often, you may want to replace it every month or 2. During the spring and fall, when the HVAC system is off and the windows are open, you have more fresh air, and likely only need to replace it once during the season.
We recommend having a few filters on standby, so you don’t have to worry about going to the store every time you need a new one.

These systems provide backup power for homes and businesses, allowing you to keep the lights on and the power up and running during a blackout.

With Labor Day behind us, it’s time to start thinking about the next season. Labor Day is the unofficial end of Summer, even if we technically have a few more weeks.

Changing your HVAC filter is one of the simplest—and most important—tasks you can perform on your own. After months of running your air conditioner, your filter fills up with dust, pollen, and any other airborne irritants that pass through. We recommend that you change the filter once every 1-3 months. At the end of the summer is a perfect time to do it.
A maintenance plan for your HVAC system is a great investment for your home. The best way to take care of your heating and cooling system is to schedule annual maintenance.

Deciding to upgrade your HVAC system is a big decision. A new HVAC system is a large investment, and one that impacts not only your wallet, but also your home comfort and energy bills for the next decade.
We recommend that you change the air filter for your HVAC system once every 1-3 months. Changing the air filter for your AC system is an important part of regular maintenance for your HVAC system, but it’s often overlooked. This is a task you can perform on your own, and one that you should learn to perform on your own.
Your air filter sits in place in your HVAC system, catching any airborne particles that may pass through in the airflow. Allergens, bacteria, dust, dirt, mold spores, and pollen are just some of the irritants that get caught in the filter and are prevented from circulating in the air. After some time, the filter builds up with these irritants and gets clogged.
We recommend that you have your AC serviced once a year, preferably before the really hot weather sets in for the summer. Taking care of your air conditioning system is important for its efficiency, performance, and lifespan. Depending on the age of your system and how much you use it, you may want to have it serviced twice a year, but as for most homes, once is enough and very beneficial.
Now that you know a bit more about why you should have your AC system serviced, you should also know the best time of year to have the task performed.
Losing power is always inconvenient, especially when it’s the middle of the summer. In our area located in Southwest Virginia and Northeastern Tennessee, we see some pretty bad storms. In 2024, there were power outages in the area that lasted for extended periods of time, and did tremendous damage. All that to say, we know how important it is to keep the power on in our homes.
In years past, when the power would go out you’d lose your TV and radio, but that was really the only entertainment that would suffer from lost power. Now, with the internet being such a focus of entertainment, losing WIFI connectivity and internet access can limit the entertainment you can enjoy. Whether you’re checking the weather, working from home, or just trying to keep the kids entertained, having power to your router and television can make a huge difference.
