Cabin air filters can capture dust, bugs, leaves, and other various types of debris. A dirty air filter can certainly impede your air conditioner's ability to cool and after time could cause unnecessary strain on the entire system. Another common potential reason is that your compressor has failed.
Believe it or not, your cabin filter can affect your AC system, and the AC can have a strong impact on the power of the entire vehicle. If your filter is clogged, then you might have to turn up the AC. The harder your AC works, the more the engine does, too.
After replacing the filter, you should wait at least 12 hours before running the system. If the AC is still not blowing cold air, it could signify that you have a refrigerant leak, a damaged condenser, or your entire mechanical system needs maintenance.
Mold can build up on the filter if you don't change it, which can cause bad odors and smells. Mold is also extremely unhealthy to breathe in, as it can make a person very sick. But by replacing the cabin air filter regularly, you can avoid breathing in that unhealthy mold and keep your cabin smelling fresh.
Using an air conditioner without a filter is not recommended. Here are a few reasons why: Dust and Debris: The filter helps trap dust, dirt, and other particulates from the air. Without it, these materials can accumulate inside the unit, leading to reduced efficiency and potential damage.
Change The Cabin Air Filter
A dirty air filter can certainly impede your air conditioner's ability to cool and after time could cause unnecessary strain on the entire system.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
The cabin air filter replacement interval can vary depending on your exact vehicle and driving conditions. However, the general rule of thumb is to replace your cabin air filter every 15,000 miles or so. We suggest you reference your owner's manual or speak to our team of experts for specifics.
While you can run a car without a cabin air filter, it's still important to replace it.
How do you know if your cabin air filter is bad? Decreased airflow from the vents, bad smells in your car, and trouble clearing a foggy windshield indicate your cabin air filter is bad.
Dirty air filters cause your AC to operate at a lower efficiency which means it does not cool your house as well as it should, and can end up costing you more money in the long run.
Common Reasons AC Doesn't Run Cold
The most common causes of broken air conditioning leaks or compression issues. If you are feeling cool — but not cold — air, the issue could be a clogged filter, a problem with the cooling fan, signs of radiator trouble, or it could simply mean it's time to recharge your AC.
A clogged filter can significantly diminish the efficiency of your vehicle's air conditioning system, preventing it from blowing cold air effectively. The primary function of a cabin air filter is to clean the air entering your vehicle's ventilation system.
If you drive a newer model, you can expect a clean cabin air filter to increase acceleration by 6-11%. Bottom line, a clean air filter will improve clean air flow to your vehicle's engine, improving gas mileage.
Many cabin filter suppliers recommend a yearly change interval of 12,000-15,000 miles. We recommend adjusting this schedule depending on the region in question and how the vehicle is used. Most often, seasonal changes in the Spring and Fall are appropriate for the cabin air filter.
Air conditioners can stop working if there is a blown fuse. Replacing that fuse can fix the problem, though it's important to have a certified car AC service technician check your electrical system.
When a cabin air filter is dirty or clogged, it's difficult for cold air to pass through the air ducts. This dirt clogs and obstructs the free flow of cool air. This is why you have hot air instead of cold air. In such cases, you will need to replace your cabin air filter.
Besides causing foul odor as mentioned earlier, an unclean cabin air filter with mold and mildew can make you sick. Plus, since the filter can't trap more particles like dust and pollen, you end up breathing unfiltered air in your car, which can worsen allergies and respiratory problems.
No, you should never run your AC without a filter!
Although there are specific situations when this may be acceptable for a very short time, in most situations running your AC without a filter could be disastrous. Generally, anytime you run your air conditioning system without an air filter you are taking a major risk.
This will vary based on your vehicle, however, a cabin air filter replacement could run anywhere between $30 and $70.
If you don't change your filter, you'll run into problems down the road. Why should I care if my filter is full? A dirty, old cabin air filter can have a negative effect on your vehicle. When your cabin air filter is clogged, airflow is restricted.
As your air filter catches unwanted particles, it's also helping your engine pull in the clean air it needs to operate effectively. But when the filter wears down and gets dirty, it can choke off your car's air flow and hurt your engine's acceleration power.
There are a number of reasons why your air conditioner might be running but not cooling. It could be an issue with the thermostat, the compressor, or the evaporator coils. Or, it could simply be clogged with dust and debris, which is preventing it from working properly.
The most common causes of broken air conditioning are leaks or compressor issues. If your air is blowing cool but not cold, the problem could be a clogged filter, cooling fan problem, radiator trouble, or it could simply be that you need to recharge your AC.
Check these issues when the unit won't kick on: Check the thermostat and adjust the settings if it isn't set to Cool and an appropriate temperature setting to call for cooling. Examine the house circuit breakers for the AC unit and reset any tripped breakers. Check the air filter and replace the filter if it's dirty.
