If you pay much attention to HVAC topics, you probably know that clogged air filters are the number one cause of HVAC system failure. When air can’t pass through a filter, it causes blower fan motors to work overtime and burn out, it increases your home energy use and it reduces the amount of conditioned air getting to your rooms. But if you’re handling your spring maintenance or just on track for your monthly air filter replacement, how do you go about changing it? This air filter replacement guide will help.
- First, check your owner’s manual to discover where the air filter is. This will vary from unit to unit. Usually, though, it’s located on the indoor evaporator in an easily accessible location.
- Open up the evaporator casing (or whatever cover the air filter has). Your air filter may be held in place by a strip of metal; remove that or move it out of the way. If the air filter is held in by screws, clips or clamps, disengage them.
- Remove the filter. If you still need to purchase a new air filter, get your current filter’s specs. Then, you may choose to replace the old filter temporarily or turn off your system until you’re done with your errand. Running your system without a filter can drag dust and debris into the inner workings of your A/C, heat pump, or furnace, which can lower system efficiency.
- Slide the new filter into the filter slot. Pay attention to the filter’s “Air In” and “Air Out” sides, and make sure it’s installed the correct way.
- Replace anything you had to remove in order to access the filter, and enjoy free-flowing air and fresh filtration.
