As a homeowner it is important to keep up with your regular home maintenance. One of them being changing the air filter for your HVAC system regularly. When your air filter is dirty it can cause the system to be overworked and inefficient, which can result in problems and expenses. A system that has a dirty filter can suffer from pressure drop, which can lead to reduced air flow resulting in no air infiltration at all. Any of these conditions can cause your system to work harder trying to keep your home cool or warm. And any mechanical component that has to work harder to run efficiently puts undue stress on the system, which can lead to premature failure, resulting in repair or replacement. Changing your filter is simple and inexpensive, and can help prevent costly repairs.
What type of air filter should I use?
There are many different types of HVAC filters. Most are disposable and either pleated or non-pleated. They are made with a wide range of filter media, including fiberglass, polyester, paper, and synthetic non-woven materials designed to trap as much airborne debris as possible. It’s important to use the appropriate filter for your system, using the wrong filter that doesn’t fit the unit properly can create the same types of problems as having a dirty filter. Your HVAC technician can tell you the appropriate filter to use and show you where the filter goes and how to remove the old one and install a new one. Your unit may also have an affixed label with directions for easy filter replacement.
How Often should I change the air filter?
You should change your air filter at least every three months, but possibly more often. In many cases air filters will need to be changed once a month, especially if you run your system six months a year to year round, you have pets, you smoke inside, you have allergies or respiratory condition, you have a fireplace, etc.
Homeowners who take care of the easy task of changing their HVAC filter can help prevent system downtime and avoidable expenses, as well as keep their families living and breathing comfortably.
