Can a Dirty Cabin Air Filter Cause Your AC Not to Cool?

Changing your cabin air filter is an important part of maintaining your car's climate control system. A dirty air filter can capture dust, insects, leaves, and other types of debris, which can cause the air blower motor to malfunction and hinder the cooling capacity of your air conditioner. This can lead to hot and cold spots throughout the house, rather than a uniform temperature. An increase in fan noise may also be due to air intake from large materials or a dirty cabin air filter.

If you're susceptible to allergies, a faulty cabin air filter can cause pollen and dust particles to reach the cabin and cause health problems. Today, many brands sell cabin air filters with the idea that no one wants to spend time in a smelly car if they can help it. But if the air filter becomes clogged, dirt will prevent cold air from flowing through the evaporator (cooling coil). If there is excess dirt on the air filter, the air conditioner will strive to cool the entire room or house.

If your air conditioning system produces warm air instead of cooling cold air, the main problem could be a dirty filter. If you have pets or use cleaning chemicals regularly, dander, cleaning particles, dust, and other debris can get trapped in the filter and then be released into the air. A cabin air filter whose pores are blocked can cause a strain on the air conditioning system, increasing energy consumption and causing damage to the motor due to overloads. An important part of maintaining your car's climate control system is changing your cabin air filter regularly.
