It’s a hot summer day, and you’re cruising down the highway in your car with the windows closed and the air conditioning blasting. Ah, relief! But have you ever stopped to think about how your car’s air conditioning system works or how to maintain it properly? Firestone provides a good guide to everything you need to know about your car’s AC system.

How It Works

First and foremost, let’s talk about how your car’s air conditioning works. Your air conditioning system consists of five main components: the compressor, the condenser, the evaporator, the expansion valve, and the refrigerant. Refrigerant is the substance that keeps your car cool, and it’s circulated through the system by the compressor. The refrigerant starts as a gas and is compressed, causing it to get very hot. It then moves to the condenser, where it is converted into a liquid, which is then cooled by airflow. From there, it moves to the expansion valve, which reduces its pressure and causes it to turn into a gas again. This process causes heat to be absorbed, cooling the air.

One important thing to keep in mind is that your car’s air conditioning system is not a closed system. This means that refrigerant can leak out over time, causing your AC system to stop working properly. Signs that your AC system may be low on refrigerant include air that is not as cool as it should be, hissing noises coming from the AC system, and a lack of cold air coming from the vents.

Change Is Good

It’s also important to change your car’s cabin air filter regularly. The cabin air filter filters out pollen, dust, and other contaminants, but over time it can become clogged and dirty, preventing air from flowing through the system properly. You should also have your air conditioning system serviced regularly, ideally once a year, to ensure that everything is working as it should be and to catch any potential problems before they become major issues.

If you notice any problems with your car’s air conditioning system, it’s important to get them looked at as soon as possible. Ignoring problems can lead to more expensive repairs down the line, as well as discomfort and even health problems from inadequate ventilation.

In addition to servicing your car’s air conditioning system, there are a few things you can do to help it run smoothly. One is to park in the shade whenever possible, as this can help keep your car cooler and reduce the workload on the AC system. Another is to turn off the air conditioner a few minutes before you reach your destination but leave the fan running. This allows the evaporator to dry out, which can help prevent mold and mildew growth.
