One of the most common problems an AC company will see when they go to a home to provide HVAC maintenance is filthy, clogged air filters. Most people believe their air filters only need to be changed with the seasons, or every three months. However, some homeowners need to change their filters monthly, while others can get away with waiting much longer. There are so many myths regarding air filters and your central air that we thought we would compile a list of the most asked questions are AC company gets from clients.
What Does the Air Filter Do?
The air filter keeps dirt, dander, and dust out of your HVAC system. Filters are generally put into the return air duct, which pulls warm air from inside to be cooled then forced back out through the vents. The air filter traps particles from the warm air and prevents them from being forced back out. Air filters not only cool, but they also clean the air. However, the purpose of this isn’t necessarily for your health, but to increase the longevity of the AC unit.
How Often Should I Change My Air Filter?
Like we mentioned above, your filter could need changing at one month, three months, or longer. The frequency will depend on how often you have your central air running. Homeowners that use heat pumps tend to need monthly cleaning or replacement. Make sure to check your filter monthly. If it’s grey and dirty, go ahead and replace it.
Clean or Replace My Air Filter?
The most common air filters are the disposable, one-use filters. These should always be thrown in the garbage and replaced. Reusable filters will have cleaning instructions, and you will most likely need a damp cloth.
The best thing you can do for your central air other than keeping the filter clean is to ensure you are keeping up with maintenance on your system through your local AC company. Let experienced professionals keep an eye on one of your most important home investments.
