What Could Happen If You Skip Air Filter Cleaning/Replacement?

Air filters play an important role in the efficient operation of your air conditioning units. However, they can become susceptible to dirt and debris and could get clogged after extensive usage. Cleaning or changing your air conditioner’s air filter is one of the smartest steps to head off potential HVAC issues. Let’s find out what could happen if you skip air filter maintenance.

Restricted airflow

A clogged air filter restricts airflow from your air conditioning unit, causing cold air to build up inside it and lowering your indoor temperature. Overtime, this buildup of cold air becomes ice on the coils. Now you can imagine what impact it can create to your unit.

Uneven cooling

Do you notice uneven cooling with cold and hot spots in your home? If yes, it could be a good sign that your air filter needs some cleaning or replacement. To head off comfort problems and higher energy bills, always keep your AC air filters clean and replace them every one to three months.


Ideally, your AC unit cycles on and off throughout the day, but those cycles significantly increase when the air filters become clogged or dirty. Short-cycling causes uncomfortable temperature swings, noise pollution and wasted energy.

Allergen Buildup

Another detrimental effect of a dirty air filter is that it causes allergen buildup. This is a serious problem for those who have allergy or asthma problems. Now you know that skipping air filter cleaning and replacement can put you and your family’s health at risk.

Wear & Tear

Proper maintenance ensures improved longevity of your unit. But when the air filter gets clogged or dirty, all the internal components will be affected which can eventually cause wear and tear on your unit. If you’re overlooking air filter maintenance, don’t be surprised if you’ll end up replacing your air conditioner a year sooner.

Luckily, the solution to these problems is simple. Keep your air filter clean and call your HVAC specialist for a periodic air filter replacement.
