FAQ:

Q: How to install a return vent filter on an air conditioner?

A: 1 Clean the vent – Turn off your HVAC unit and open the vent grille. … 2 Cut to shape – Many return vent filter brands consist of rolls, where you must cut it to conform to the shape of your vent. … 3 Press to adhere – Press the filter onto the tape you secured to the grille and hold for several seconds. …

Q: What are the benefits of a return vent filter?

A: Protection for primary air filter – Using a return vent filter will extend the life of the main air filter at your HVAC unit. The filter at your return vent will pre-filter out any dust and debris. This helps prolong the life of the expensive pleated air filter at your HVAC unit.

Q: Where is the air filter on a heat pump system?

A: If you own an older home that has return air vents in each room, you likely have a central location where the air filter is installed that is closer to the heat pump system. Most heat pump systems (particularly split systems) will have a filter slot at the end tag where the air return duct connects to the air handler.

Q: Where is the return air vent on a thermostat?

A: The return air vent will be located on the wall, in the ceiling, or in the floor on some older homes. The return air vent is generally much larger than the supply vents located in your floor ceiling. This is because you usually only have one return air vent per thermostat.
