Where is the Air Filter Located in Your Home?

If you're asking yourself: “But where is the air filter in my house?” Don't worry, we've got you covered. First, let's talk about why it's so important. Usually, the air cleaner is close to your home thermostat, in a return duct. Or, it's most likely right next to the air handler for your air conditioning system.

The next step can be more complicated to find the air filter. It can be difficult to locate in some HVAC systems, but you can usually find the air cleaner in the return air duct. Or in simpler terms, that large metal grille on the wall, floor, ceiling, or door of the utility closet. Return air ducts can be virtually anywhere. Unlike smaller ducts around your home, the return air duct or blower compartment draws air from your home and sends it to your HVAC unit for heating or cooling.

Replacing the air conditioner filter in your home will allow the unit to continue to blow cool air without interruption. Whether you're moving to a new home or always letting the technician take care of the work during annual tune-ups, you need to know how to locate the air filter in your home. It is usually located in the return air duct or in the fan compartment before the return air reaches the air handler. If you recently moved or bought a new home, you might be wondering where your HVAC air filters are located. It brings expert knowledge of a wide range of home air filtration topics, including HVAC filters, filtration efficiency, and indoor air quality.

They can help you locate air filters and show you how to change them, so that next time is easier. The air handler draws air from the home through the return duct system and then blows the air through the heating or cooling system and returns it to the house through the duct system. In this case, the air filter is most likely located right next to the boiler air controller or air conditioning system. It's important to have a good air filter installed to trap allergens and other irritants, so they don't circulate around the house. Since HVAC units are generally hidden in smaller, less convenient spaces, some homes are configured for air filters on the return grilles. Knowing where your HVAC system's filters are located is essential for keeping your home comfortable and healthy all year round.

Regularly changing your filters will help keep your HVAC system running efficiently and reduce energy costs while improving indoor air quality.
