Why Is Replacing The Air Filter Important?

Proper maintenance of your AC and furnace will assure good air quality in your home, increase the lifespan of your system, and consume less energy, resulting in lower bills. Your filters should be changed every 30 to 90 days, depending on the type and efficiency of your filter. During peak winter and summer months, your HVAC system is operating at its highest capacity, and it's recommended that you change your air filter every month. Remember, regular maintenance of your home's cooling and heating system is essential to ensure it operates efficiently.

How Do I Change My Air Filter?

Hi, it's Jen from Air Filters Delivered to show you how to install an air filter in your home air conditioning system. The air filter for any central heating and air conditioning systems goes in one of two places: your air return vent or in the actual air handler or furnace. In either case, go ahead and turn your unit off so, as you are changing the filter, you don't accidentally suck a bunch of spilled dust and grit into the unit and undo the good work your filter has done.

For an air return vent, just flip the latch and open the hinged screen. Remove your old filter. Now, on the side of your new filter, there will be some arrows showing airflow. Place the filter in the vent with those arrows pointing into the duct. Close that up and you're done. Too easy!

Remember, if you have two-zone air conditioning as in many two-story homes, you will need to replace filters in each. Any forced air system uses an air filter, so if you don't see a hinged air return vent in your home, it will be in your central unit. Whether it's an air handler for an AC system, heat pump, or furnace, open the access panel which will normally have some hand-screw knobs at the corners. Your old filter will be there, right where the air return duct meets the unit. Remove that. Now, check that airflow arrow on the side of your new filter. Place the new filter in your unit so that the arrow points from the return duct into the actual unit. Replace the access panel and turn your unit back on.

And remember, Air Filters Delivered is the perfect place for replacement filters. You can find any size available and, with our price match guarantee and free shipping, it's hard to go wrong. - let us fetch your filters.

Additional Helpful Tips

  • Choose the right size filter. Before buying a replacement filter, check your owner's manual to identify the right number or size of your filter – it could also be printed on the side of your existing air filter. Or measure the filter yourself for accurate sizing.
  • Turn off your HVAC unit. For safety, turn off your HVAC unit before attempting to change the furnace filter. If you can't figure out how to turn off the unit, turn off the breaker.
