How to Find the Air Filter for the HVAC System in Your Home I can’t find the air filter in the HVAC unit in the home we just bought. Do all central heating and cooling units have filters? All central heating and cooling systems should have an air filter, but the filter can be harder to locate on some HVAC units than others. The air filter is usually located in the return air duct or blower compartment before the return air reaches the air handler. This allows the filter to clean the air coming from your house before it enters the HVAC unit. Common locations for air filters in HVAC units include: On horizontal HVAC units with the return duct attached to the side of the air handler, the filter often fits in a slot on the return air (intake) side of the unit. On vertical air handlers with the return air duct entering on the top of the air handler, the filter often slides into a slot above the HVAC unit. On vertical air handlers with the return air duct entering below the air handler, the filter often fits in a slot located below the HVAC unit.

On other HVAC systems, the air filter may be located behind the return air grill on a wall in your home. On HVAC systems with a return in each room, there may be an air filter behind each of the return grills.

Remembering to change air filters when needed. When To Change Your Air Filters This is not a trick; simply put – when your air filters are dirty, change them. Choosing how often to change your air filters can depend on several factors: Type of filter your A/C system requires The overall air quality of your your city area home Pets – Birds, cats, dogs, hamsters (do you have one?), etc. Number of occupants in the house General air pollution in the your city area or construction taking place nearby For your typical 1"-3" air filters, the manufacturer specs basically say to change them bi-monthly, which is in fact a great rule of thumb. However, general guidelines are not applicable to all. If you have to tolerate light to moderate allergies, you may need to upgrade the air filter or change them even more regularly than OEM specifications.

On the other hand, if you're in a remote area, own a infrequently occupied home (like a vacation home) or an area where there are fewer cars around, replacing your air filters each year may be quite sufficient. Why do pets matter so much? They have a tendency to shed, which can clog your air filter fast. Clearly, the air filter is just doing its job by capturing pet hair and dander, but tremendously dirty filters can cause weak HVAC performance.
