Can a Clogged Cabin Filter Affect Your AC Compressor?

Cabin air filters are designed to capture dust, insects, leaves, and other types of debris. When these filters become clogged, they can hinder the cooling capacity of your air conditioner and put unnecessary strain on the entire system. This can lead to an increase in energy consumption, motor damage due to overloads, and a noticeable reduction in power when the AC is turned on. In more severe cases, it can even cause a blowout.

People with allergies may suffer if the air filter in the air conditioner is not cleaned regularly. It's important to check the cabin filter or change it at regular intervals to ensure that your home is well sealed and that you have no pets, no furniture or carpets prone to dust, and that you vacuum every day. If your central air conditioning unit hasn't worked as it should lately, a dirty air filter could be the culprit. Licensed technicians can take a look at your air filter and clean or replace it if necessary.

Here are three signs that the cabin filter is clogged so you know when it's time to replace it:

• You may notice an increased amount of dust and possibly allergens in the cabin.
• The AC system may consume more energy.
• You may hear a soft, healthy fan noise.

A clogged cabin air filter can cause a strain on the air conditioning system, reduce HVAC efficiency, and reduce the heating and cooling capacity of the vehicle. It's important to shake the filter after washing to drain any excess water that may be trapped in the filter, then allow it to air dry before returning it to the air conditioning unit. If you don't want to contribute to that number, it's best to replace the cabin air filter after using it for a couple of years, as it won't work in the best way. To be safe, be sure to check the cabin filter or change it at regular intervals.
