Why This Monthly Reminder Matters
A clean filter protects your blower motor, keeps airflow strong, and improves indoor air quality. Regular furnace maintenance also helps catch small issues before they become big repairs.
What You’ll Need
- A new filter that matches your current size
- A flashlight
- A trash bag for the old filter
Step-by-Step: Replace Your Furnace Filter
- Turn the thermostat to Off. Give the system a minute to stop running.
- Find the filter slot. It’s usually in the return air grille, the filter cabinet next to the furnace, or inside the blower compartment.
- Note the size on the filter frame. Match it exactly for the best fit.
- Check the airflow arrow on the new filter. The arrow should point toward the furnace and away from the return grille.
- Slide the old filter out slowly. Keep it level so dust doesn’t spill.
- Insert the new filter with the airflow arrow pointing the correct direction. Make sure the edges sit snug with no gaps.
- Set a reminder to check it again next month. Homes with pets or construction dust may need more frequent checks.
- Turn the thermostat back to Heat and confirm airflow at a nearby vent.
