How To Change The Air Conditioning Filter

AC air filter replacement is a simple task. Before you begin, you must first determine the location of the AC filter. That can be difficult because there are various possibilities, depending on the type of air conditioner you have.


The filters in some systems are situated in the return air duct. This is the one that draws air from your room back into the air handler system of your air conditioner. If you have a large system with several air handlers and return ducts, finding the filters can be difficult.


Is your heating and air conditioning systems share the same ducts? Both systems’ air filters may be near the furnace’s blower. If so, it’s normally near the bottom of the furnace, near the front. You may be able to view and access the filter without having to open anything, or you may need to open a metal panel (labeled FILTER) on the front or top of the blower. Hooks or screws can be used to secure the panel.


Your best bet is to consult with your HVAC service technician. Simply tell him you want to learn how to change the AC filter, and he’ll teach you where the filter is, how to remove the old one and insert the new one, and where to purchase the correct filters for your system.

Replace Return Air Filter

Follow these simple procedures to replace a central air conditioner filter:


  • First, remove the cover grille’s latch.


  • Wipe down the grill with a microfiber cloth. If dust has accumulated between the slats, use a microfiber cloth wrapped around the tip of a flat screwdriver to carefully wipe in between the slats, or vacuum the cover with a brush attachment.


  • Insert a new filter, making that the furnace filter is pointing in the right direction.


  • Close the cover grille and fasten it shut.


  • Replace the air filter in your return air duct, air handler cabinet, window AC unit, and furnace as needed.

Air Handler Filter Replacement

  • Turn off the HVAC unit’s electricity. If you’re not sure how to turn off your furnace, see the owner’s manual. Do not use the furnace without a filter.


  • Remove or unlatch the door and clean it according to the instructions above.


  • Examine the filter type. Replace it with a new filter in the appropriate size if it is disposable.


  • If the filter is reusable, brush it first to remove surface dirt before running a vacuum with a soft brush attachment over the face to remove any remaining embedded dust and dirt.


  • Run water through the filter in the opposite direction of the airflow; a low-pressure spray can help with cleaning.


  • Allow the reusable filter to air dry completely before replacing it.


  • Do not restart the HVAC unit until the clean, dry filter is installed.

AC Filter Replacement Step-by-Step

FIRST AND FOREMOST, if coronavirus particles are present in your environment, they may become trapped in your AC filter. Wear a mask and gloves when changing the filter.


-This is crucial for two reasons. The first consideration is your safety. Don’t come into contact with live voltage! The safety of your equipment is the second factor. Dust and debris might be drawn into the unit if the machine is still operating while you remove the blocked filter. You must turn off the power at both the unit and the circuit breaker.


-Simply slide it out of the slot that has been holding it in place.


-Check the condition of the AC filter once you’ve removed it. Does it appear to be clogged with dirt and dust? You probably won’t notice much light coming through if you hold it up to the light. Depending on the type of filter, this filter must be updated or cleaned. Replace it even if it has been in use for less than the time recommended by the manufacturer. Many things can influence how quickly your filters clog. Smog alone can shorten the life of an air filter in Chicago.


-If there are impurities on the filter, store it in a plastic bag and dispose of it in a trash can outside your space.


-Are you using disposable or reusable filters? A disposable filter is comprised of cardboard and paper or fiber mesh. Permanent, reusable filters have a metal frame and washable coating. Check the manufacturer’s washing directions if you’re cleaning a reusable one. You’ll most likely only need to rinse it with water and allow it to dry entirely. In certain circumstances, you can just vacuum the dust away.


-All that remains is to reassemble it properly. An arrow on the filter’s frame points away from the return air duct and toward the air handler. When reinstalling the filter, ensure the arrow points away from the return and toward the air handler.


Wasn’t that simple? Set a reminder for yourself now that you know how to change an AC filter so you remember to do it monthly. Also, if your furnace’s filters are separate from your air conditioner’s, don’t forget about them.
