Why Do Air Conditioners Need Filters?

If you’re like most homeowners, you probably change your air filters at least a couple of times each year, but you know you don’t do it as often as you should. Why do you need to, anyway? What are these filters doing to make your home safer?

Aside from just keeping your breathing air clean and devoid of harmful debris, filters perform a handful of important jobs that improve the quality of life inside your home. Here are the top three reasons why you need clean filters in your air conditioning systems.

1. Air Filters Prevent Your System From Getting Damaged

Not only do the filters keep dirt and dust out of your home, but they also prevent the debris from traveling into the air conditioner’s evaporator coil. When this coil gets dirty, it can cause the entire system to malfunction or even leak. By switching out the filters often, you’ll prevent future problems with the system and save money on repairs.

Additionally, air filters make sure that the system’s condensate drain can properly remove condensation and moisture from the unit. This prevents worrisome water leaks from occurring, as well as clogs in the HVAC system.

2. Air Filters Protect the Ducts From Mold Growth

As debris gathers in the ductwork of your HVAC system, something gross begins to happen. The dirt clumps together and spreads moisture, which leads to the growth of mold spores. The fungi can then travel throughout the ductwork, compromising the air quality and causing serious health problems amongst the building’s residents.

3. Air Filters Save You Money in the Long Run

As your home’s air conditioning system pulls air from inside the home and blows it across the copper tubing, the air comes in contact with Freon. If the air hasn’t been filtered, the debris will stick to the tubes, causing your entire system to overload. This can be a pricey problem to repair, and the inefficiency of the system can jack up your utility bills.
