Where Are My Air Filters Located?

All central heating and cooling systems have an air filter, but the location of the filter can vary from one unit to another. Most air filters are relatively easy to locate, but others can be somewhat difficult.

Below is a quick  guide to assist you when locating your air filters.

  • On HVAC systems with  a return in each room, there is typically an air filter behind each return vent.
  • If you are dealing with a horizontal HVAC unit where the return air duct is attached on the air handler’s side, the filter is often found in a slot on the intake side of the unit.
  • If you have a vertical air handler that has the return air duct entering on the top of the air handler, the filter most likely will slide into a slot that is located just above the HVAC unit.
  • If you have a vertical air handler with the return air duct entering just below the air handler, the filter will fit into a slot that is located just below the HVAC unit.
  • On other HVAC units, the air filter might be behind the return air vent on a wall inside your residence.

The Importance of the Air Filter

Just as the name implies, air filters clean the air. They do more than just keep out dust and pollen, they also keep out larger particles and protect your HVAC system from damage. HVAC problems can commonly occur if filters are unchanged after they have become too dirty and clogged. After reading that you’re probably looking around at your vents to see how dirty they look! If they’re visibly dirty just by looking at them, that’s a bad sign.

There are risks that you can face when you don’t change the air filter on your HVAC system in a timely manner. It will accumulate dust, mold, and other dangerous particles that will be released into the air and negatively impact the indoor air quality. When you have a clogged air filter, it will take more energy and your utility bills will increase considerably. Clogged filters will force your system to work overtime which leads to higher energy costs.

How To Keep Your HVAC Up To Par

You can prevent potential problems and keep your HVAC unit in tip-top shape and ensure you have the best air quality possible. It’s as simple as making sure you have the air filter changed regularly. It’s also wise to have your HVAC unit inspected regularly to be sure everything is working properly. Golden West Plumbing, Heating, and Air Conditioning performs dozens of inspections each week.

When Should You Change Your Air Filter?

You should change your unit’s air filter every 1-3 months. If you’re in an area with a lot of pollen and dust, it would be best to change them sooner rather than later. You should review your owner’s manual for your unit, and it will tell you what kind of filter you will need and what the minimum efficiency reporting value (MERV) range that your specific unit should fall into.
