Chill with Confidence: Ace the 2025 ASE Air Conditioner Exam and Keep Cool Under the Hood!

A clogged cabin air filter can significantly restrict airflow within the vehicle's air conditioning system. As the filter becomes blocked with dust, debris, and other particulates, it hinders the movement of air into the cabin. This decreased airflow can lead to a few key issues.

First, it puts extra strain on the A/C blower motor, which has to work harder to push air through the restricted filter. Over time, this increased effort can lead to premature wear or even failure of the blower motor. Additionally, because the air is not flowing as freely, the overall performance of the A/C system may diminish, resulting in less effective cooling.

Moreover, the reduced airflow can create pressure imbalances in the system, leading to more potential complications and inefficiencies. Thus, this decreases airflow and increases system strain is a logical consequence of having a clogged cabin air filter.
