Changing your air filter is vital to increasing the longevity of your furnace and air conditioner. These filters trap pollutants and dust so that you don’t have to breathe them in, but if they get too full your appliance has to work harder. These filters should be changed monthly during high usage seasons; summer for your air conditioner and winter for your furnace. No idea how to change them? Here’s a step by step guide:
1. Turn off your system.
2. The filter will be located close to the intake-outtake blower (in most homes it’s close to your control box). There may be a door or panel that swings or lifts open; open it and remove the filter.
3. Before you install your new filter look around the edge to find an arrow. This arrow tells you the direction of the filter. Make sure the arrow points to the blower and is not installed backwards (check the direction of your old filter before you take it out or just as you remove it if you’re not sure which way it goes in)
4. Lastly, turn your system back on and make sure it’s functioning properly.
All filters will come with a MERV (Minimum Efficiency Report Value) rating, and the higher the rating, the higher the efficiency of your air filter, which means more particles will be pulled out of your air. Just remember, disposable filters are supposed to be changed every month. If you have problems changing your filters, call your local HVAC contractor, he will be happy to help you!
