Why Do I Have to Replace the Air Filter in My Air Conditioner?

While the purpose of the standard air filter in your AC isn’t to improve your home’s indoor air quality, it does serve a very important purpose: trapping excessive amounts of dust and dirt. At this time of year, your air conditioner runs pretty regularly, so it is capturing a great deal pf particles. Air filters cannot remove these particles on their own; instead, they need to be changed out every three months to ensure they work well and your air flow is good. What can happen when you leave a clogged, dirty air filter in your air conditioning system? Let’s take a look:

Low Air Volume

One of the most common problems that develops when an air filter is too full is the reduction in the amount of air moving through your system. This leads to other issues because your AC is designed to work with a specific amount of air. So, not only is your cooling compromised, so is your system.

Icing

Icing is never a normal occurrence with your AC. The reason it can develop with a clogged air filter is that part of what healthy air flow does is push heat from the system and blow the cool air into your home. Ice develops when the warm parts are too hot and the cool parts are too cold. Condensation is formed, then quickly freezes on the cold parts. The issue won’t be resolved until the air filter is replaced.

Big Decrease in Energy Efficiency

When your system doesn’t get enough air, it operates in a state of continuous stress. Stressed ACs need more energy to achieve your set temperature, even when you haven’t changed your set temperature. The result is more energy usage and bigger energy bills.
