Can a Dirty Air Filter Stop Your Car's AC from Cooling?

Changing the cabin air filter is an important part of keeping your car's air conditioner running smoothly. Cabin air filters can capture dust, insects, leaves and other types of debris. A dirty air filter can certainly hinder the cooling capacity of your air conditioner and, after a while, could cause unnecessary strain on the entire system. You'll notice that the air conditioner starts emitting unpleasant odors once you turn it on, and you will also experience a change in the quality of the air conditioner; you will start to feel hot even if the air conditioner has been on for quite some time.

Many people wonder if a dirty air filter can keep their air conditioner from cooling down. The answer is yes: a dirty filter can create several problems that can hinder the effectiveness of your unit. Not only will this cause the air conditioning system to operate less efficiently, but it will also cause the engine to run less efficiently. As a result of the buildup, a dirty filter will also cause poor cold air flow in the air conditioning system.

Experts such as those at Degree Heating & Cooling recommend changing the filter monthly for best results. One of the most common symptoms that indicates that a cabin filter needs to be replaced is reduced airflow; you'll notice that less air is being expelled from the air conditioning system grilles. When the filter is dirty or clogged, less air can pass through and the air that can pass through requires more effort than normal. Not to mention that when a dirty filter constantly forces your air conditioning system to work overtime, it causes significant wear and tear on your unit.

Dirty air filters keep your air conditioner running at a lower efficiency, which means it doesn't cool your home as well as it should and can end up costing you more money in the long run. Sliding a wet filter back into the air conditioner only requires icing and other problems, and trying to dry the filter is likely to damage its delicate surface. The filter of an air conditioning unit is an incredibly important part that cleans the air that enters it. A good air filter helps prevent dust and dirt from accumulating on all internal components of the unit; a bad one will cause additional wear and tear that can lead to serious maintenance problems in the future. 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. When your car's AC isn't cooling as well as it should, check your cabin air filter first.

To clean the reusable air filter, remove the filter from the air conditioning unit and rinse it in a tub or sink with warm water. If your air conditioner continues to work, licensed technicians can take a look at your air filter and clean or replace it if necessary. It is also recommended to change engine and cabin air filters once a year or every 15,000 miles. A dirty air filter restricts the flow of cold air, causing it to build up inside the air conditioner and lower its internal temperature. This means that when you turn on your car's AC, it won't cool as effectively as it should.

So if you want to keep your car's AC running smoothly and efficiently, make sure to check your cabin air filter regularly.
