3 Problems Caused by Dirty Air Filters

We’ve mentioned before how important it is to keep your air filters in your HVAC system fresh. It may sound like a minor detail, but it is far and away the most important maintenance step that you yourself can take to keep your air conditioner functioning properly. A very simple, routine task such as changing your air conditioner really can benefit you in a big way.

Review the following post to learn a bit more about some problems that may be specifically caused by dirty air filters. We think you’ll see the benefit of a keeping a clean filter in your air conditioner in Bolingbrook, IL. Contact us with any questions that you may have. 

Poor Energy Efficiency

One of the major issues that homeowners with clogged air filters will encounter is, naturally, reduced energy efficiency. Just think about blowing through an unobstructed straw. Now imagine that there are a bunch of balled up pieces of paper in that straw. Try as you might, you cannot blow them out, and that means that you have to work a lot harder to force air through the straw. That is essentially what happens to your AC when there is a dirty air filter in place, and you’ll see that reflected in your energy bills.

Subpar Indoor Air Quality

When your air filter is dirty enough, it can actually be easier for your system to force air around the air filter, than through it. It’s not like the edges of the filter are welded to your system, after all. If a dirty air filter is really restricting airflow, you may be allowing unfiltered air to infiltrate your home.

Icing of the Coil

Your air conditioner does not generate cool air. It removes existing heat from the air in your home by evaporating refrigerant in the evaporator coil. If your filter is too dirty and airflow resistance to high, that coil can get too cold. This can cause condensation to freeze upon it, which in turn insulates the coil further. This impedes performance quality, decimates efficiency, and puts your compressor at risk of overheating.
