Finding Your System’s Air Filters

Finding Your System's Air FiltersKnowing where the air filters are for your HVAC system could be the difference between a system that keeps your home comfortable winter and summer with reasonable energy costs, few repairs and acceptable indoor air quality.

Many of the HVAC systems in the Yuma area are split into two parts and called split systems. The air handler sits indoors and the condenser for the air conditioner and heat pump sit outside. The air filter will be either inside the air handler or in the return ductwork. If you have a package system where the air handler and the condenser are one piece and sit outdoors, you’re likely to find the filters at the return air duct inside the house.

Tracing Air Filter Locations

  • In the event that it’s not clear where the air filters go, you can trace them by turning on the HVAC system and using your hand to feel which way the air is blowing through the ducts. When you find the grill, the filter should always be placed with the ‘air flow arrow’ in the direction of the air flowing into the air handler. Sometimes called a cold air return duct. You may have one in more than one room.
  • Newer homes in the Yuma area often have return ducts in the ceiling or on a wall. You’ll see a frame around a vent grill that’s held on by quarter turn screws, thumb screws or a latch. You will need to open the grill to find the air filter.
  • A few Yuma homes have air handlers in the attic. Their filters may be in the ceiling or wall.
  • Some homes have air handlers that place the air filter inside the air handler’s door.
