Introduction
Over time, dirt and dust build up in your heating and air conditioner filters. This reduces air flow and makes your equipment work harder to keep your home comfortable, which in turn, wastes energy and money. Clogged filters can even cause your system to overheat and can harm the air quality in your home.

Below are a few basic tips. Check your equipment manual or call your HVAC professional if you need help finding and changing your filters.
1Find your air filter
Different air conditioning and heating systems have different locations for filters. If you have a central AC system, the filter may be behind the main vent that lets cool air into the house. For window AC units, it is usually directly behind where the cool air comes out.
Your heater filter might be inside the furnace or inside the return air vent. Before removing and replacing your filter, make sure to turn your unit off so no air is flowing while you try to replace it.
2Check air filters regularly
How often you need to change your filters will depend on a number of things, including what type of air filter you have, the air quality in your house, how many people are in the home, and if you are in an area of high pollution or construction. For example, households with pets or lots of dust will require changing air filters more often. Start off checking your filter monthly until you can see what your filter needs will be.
