Can a Dirty Air Filter Cause My Air Conditioner Not to Cool?

It’s been a warm summer, and that means you probably have run your home’s air conditioner quite a bit. If it isn’t cooling your home as well as you’d like, the best first step is also the easiest – check your filter. Many people wonder, “Can a dirty air filter cause my AC not to cool?” The simple answer is yes – a dirty filter can create several problems that can hinder your unit’s effectiveness. Not to mention, a dirty filter can also lead to premature failure of your system. Experts like those at Degree Heating & Cooling recommend changing your filter monthly for best results.

Dirty filters can cause a whole host of problems for homeowners. First of all, they can cause allergens to build up in your home. When the filter is dirty, allergens can’t get trapped in the filter like they’re supposed to. So, they start building up in your ductwork. The result? The air released into your home every time your air conditioner runs is full of allergens, like pollen, spores, dander – and even bacteria. This leads to poor indoor air quality and can cause you and your family some unpleasant physical symptoms, like stuffiness, sneezing, and itchy eyes.

As a result of the buildup, a dirty filter will also cause poor cold airflow in your air conditioning system. That cold air will be trapped inside your air conditioner, causing ice to form on its coils. Once that happens, your air conditioner will freeze up and become inoperable. Before your system freezes up completely, however, there will be a few telltale signs you should look out for. Uneven cooling throughout your home is one of them. If you notice some rooms are more difficult to cool than others, while others constantly feel cold, you’ll want to check your AC filter first.

One of the most obvious signs of a blocked, dirty filter is air conditioning system inefficiency. Clogged filters force your system to use more energy to cool your home. And that translates into a higher utility bill. Not to mention, when a dirty filter constantly forces your AC system to work overtime, it causes some significant wear and tear on your unit. And ultimately, that can lead to system failure long before breakdowns or the need for repairs should happen.

Of course, some people don’t change their filters because they’re not sure where the filter is located, or they’re unsure of how to actually change it.
