Replacing the air filter in your air conditioning unit is an important part of routine maintenance. It's a job that you can easily do yourself if you know how, and it can help keep your HVAC system running efficiently and reliably for years to come. Here's a step-by-step guide on how to replace the air filter in your AC unit. First, you'll need to turn off the unit. According to ENERGY STAR, you should check and change your air conditioning filter every month during peak season.
If you're not sure when to change it, ask your HVAC service technician for advice. Next, locate the filter. It's usually located in the return air duct or near the blower compartment. Make sure to measure the old filter or make note of its dimensions, if they are printed on the housing, before throwing away the old filter. This will help you buy a replacement filter of the same size. When buying a new filter, you may want to invest in HEPA filters with a MERV rating of 10 or higher if you want to improve the air quality in your space by eliminating pollen, mold, and other harmful contaminants.
If you have an electronic media filter, you don't need to worry about replacing it every 1-3 months. You can wait 6 months to a year before replacing it. Once you have the new filter, insert it into the return air duct or blower compartment with the arrow on the frame pointing away from the return air duct and into the air treatment mechanism. Make sure it fits snugly and securely. Finally, turn on the unit and check that everything is working properly. If everything looks good, then you're done!Replacing your AC unit's air filter regularly is an important part of keeping your HVAC system running smoothly and efficiently.
