The Simple Guide to Changing Your Return Air Filters

Easy Steps for Cleaner Air and a Healthier HVAC System

Flintrock Builders recommends changing your home’s return air filters once a month to keep your air fresh and your HVAC system running smoothly. Regular filter changes help prevent dust and debris from clogging your system and ensure you’re breathing the cleanest air possible. Here’s how to do it in just a few simple steps!

Step-by-Step Instructions:

1. Locate All Return Air Vents
   Every home has at least one return air vent, but some may have up to five. Take note of each location and document the filter sizes to make buying replacements easier.

2. Turn Off the Thermostat
   Set your thermostat to OFF and the fan to AUTO before starting.

3. Open the Return Air Vent
   Find the small metal tabs on the vent. Flip them down to open the vent and access the filter inside.

4. Remove the Old Filter
   Carefully take out the old filter from the vent.

5. Inspect the New Filter
   Before installing the new filter, check for any holes or tears. It should be in perfect condition to work properly.

6. Install the New Filter
   Ensure the arrow on the filter is pointing towards the air handler (usually in the attic). This means the arrow should point up towards the ceiling.

7. Close the Vent
   Gently close the metal vent, making sure not to pinch or damage the new filter. Flip the metal tabs back to their original position.

8. Repeat for All Return Air Vents
   Follow these same steps for each return air vent in your home.

By changing your filters regularly, you’ll improve your home’s air quality and help your HVAC system work more efficiently!
