Every HVAC System Uses a Filter — Here's Where to Find Yours

Whether your home has a furnace, a heat pump air handler, or a packaged unit, there's a filter inside it that needs periodic replacement. Location varies by setup: horizontal air handlers (common in WNC attics and crawl spaces) usually have the filter slot on the side or underside. Upflow furnaces position the filter at the bottom, near where the return duct connects. Some homes feature a filter grille built into the wall or ceiling of a central hallway — that's the return air grille, and the filter slides in from the face. If you've never located yours, check each of these spots.

Dealing With Different Filter Setups

Some systems use multiple return vents, each containing its own filter. If return grilles are spread across several rooms, inspect every one. Other setups rely on a single large filter at the air handler with no filters at the return vents. A handful of older installations use filters in both locations — at the returns and at the air handler — which creates excessive airflow resistance. If you discover filters in both places, pull the return vent filters and rely only on the air handler filter. Have a technician confirm the best configuration during your next HVAC maintenance appointment.

Step-by-Step Filter Swap

Switch the HVAC system off before changing the filter — even a brief moment of operation without one lets dust pass into the equipment. Remove the old filter and note the directional arrow on its frame, which indicates airflow direction and should point toward the air handler or furnace. Slide the new filter in with the arrow oriented the same way. When there's no arrow, the side with the wire reinforcement grid faces the air handler. Close the filter door or grille firmly. Restart the system.

Building a Schedule You'll Actually Keep

The ideal filter-change schedule is whichever one you'll consistently follow. Set a recurring phone reminder for the first of each month during heating and cooling seasons. Buy filters in multi-packs so you always have a replacement on hand. For homeowners in Asheville and WNC, April and October are natural times to install fresh filters as you shift between cooling and heating modes.
