The 5 Common Reasons Your Car Air Conditioner Doesn't Work

Air conditioning is one of the most important features in any car. When your air conditioning isn't working, it can be frustrating and uncomfortable on hot days. Unfortunately, there are many reasons why this might happen. Here are the five most common ones you might have come across.

Your car is old

It might seem like we're always on the prowl for the latest and newest vehicles, but if your air conditioning isn't working, it's not because you didn't buy a new car. Older cars can be more difficult to work on and less reliable, and they also require more maintenance.

When you have an older car with a lot of miles on it, you might notice that your air conditioner doesn't work as well as it used to. In this case, there's a good chance that one or more of the belts that drive your compressor have snapped or worn down. This is something that should be fixed by an Auto AC repair Austin professional mechanic quickly—you don't want to risk further damage to your vehicle.

You have a leak

A leak can cause your car to overheat and can be a costly fix. You need to have the leak fixed as soon as possible, though it's often hard to find. One way to check is by looking for signs of oil or water on the coolant reservoir. If you notice any of those things, then it's time to call a repair shop.

You have a dirty filter

If you have a dirty air filter, this could be the reason why your car is not cooling.

The air filter is a crucial component of your car's heating and cooling system. It helps keep dirt and debris from blocking the airflow that cools your engine. If there's a lot of dust or grime on the air filter, it will slow down the air flow to the engine and back out to the cabin. In some cases, dirt can even get into your car's evaporator coil. When this happens, your air conditioning will stop working altogether.

You can either replace or clean your filter so it will work properly again.

The drain tube is blocked

If the AC drain tube is clogged, it won't drain the water that collects under the car. This means that in addition to not being able to cool your car, you'll also have an annoying puddle of water.

Your car needs a recharge

A car's air conditioning system is powered by a refrigerant called R-134a. This refrigerant is released into the evaporator, where it cools the air. If your car needs to be recharged with refrigerant, you might notice that the air coming out of the vents is warmer than usual or doesn't seem to be cooling at all.
