Can a Dirty Filter Damage an AC Unit?

A clogged air filter can quickly wear down an air conditioning system, leading to costly repairs and maintenance problems. If left unchecked, the indoor unit can't move air efficiently and the system components can freeze. This is because the system can't dissipate cold in the environment. Replacing the compressor is one of the most expensive repairs for an air conditioner, so it's important to replace the filter right away.

The purpose of an air filter is to filter out microscopic particles such as dust, pollen, pet dander, bacteria, plant spores and mold, and even smoke. If your air conditioner continues to work, licensed technicians can take a look at your air filter and clean or replace it if necessary. Air filters have a nominal cost compared to the cost of repairing or replacing your home's heating and cooling system. Checking for a dirty air filter is one of the first steps you should take when you notice a problem with your unit.

If the filter becomes too clogged with dust, dander and debris, then the blower has to work harder to get air through the blocked filter. Since filters are one of the most important parts of an air conditioner, they must be properly maintained for an air conditioning system to work properly. There are many ways to keep your air conditioner well-maintained and running efficiently for longer. Depending on how old your air conditioner is, you may need to perform full maintenance on it, not just clean or replace the filters.

To clean the reusable air filter, remove it from the unit and rinse it in a tub or sink with warm water. During summer months, you should plan to change filters every month.
