How To Properly Maintain Your Car’s Air Conditioner

During the summer, it’s crucial to have your car’s air conditioner properly maintained. Not only will this keep it cool, but it can also improve your gas mileage and help you avoid a costly repair.  Although most parts of a vehicle’s air conditioning system aren’t easily accessible, some maintenance issues can be addressed by the driver. These tips can help you maintain your car’s AC and keep it running efficiently for years to come.

1. Check The Air Filter

When it comes to keeping your car’s air conditioner running smoothly, one of the most important steps is to regularly inspect and replace your cabin filter. A dirty cabin air filter can restrict airflow from the AC vents, causing your system to work harder to keep you cool or warm.
You’ll want to check the filter’s color and appearance to see if it’s clogged with dust, dirt or particles that are too small to be visible. If it looks like it’s discolored or a dark shade of gray, it’s time to change it. Your vehicle’s owner’s manual should have detailed information on where and how to remove the filter. Most vehicles allow easy access without removing the glove box, but some require a screwdriver or other tool.

2. Clean The Condenser

The condenser is a critical component of your car’s air conditioning system. It removes heat from the refrigerant gaseous cooled system to create cool air for your interior. A dirty condenser can affect the performance of your AC. Over time, this can lead to increased wear on your entire AC system and can cause it to break down. Cleaning the condenser can help improve its performance and increase its lifespan. It also helps lower your utility bills and save you money in the long run. To clean the condenser, start by using a degreaser to loosen up any debris that may be stuck on it. Next, use a hose to spray it down with water. Then, you can use a soft-bristle brush to remove any accumulated dust. Finally, reinstall the condenser panels in the proper order. This will make the process go quicker and easier.

3. Clean The Vents

Your car’s air conditioning system is a vital part of keeping your car comfortable. It works by changing a substance called refrigerant from gas to liquid and back again. Over time, air vents can get dirty. That’s especially true of the narrow spaces between the slats on your car’s vents, so they need to be cleaned regularly. Use a cotton swab to wipe away dust and grime from the vents. Be sure to rinse off the swab when it’s done. Another option is to purchase a foam paint brush. These are inexpensive, easily available and will work well for getting deep into the vent slats to remove dirt. And for a more thorough cleaning, you can combine a solution of warm water and white vinegar to spray inside your vents and the slats on top. This will also kill any bacteria that may be causing a musty odor.

4. Check The Compressor

The compressor is one of the most important components in your air conditioning system. It ensures that you get cool air in your car, regardless of how hot it is outside. Hence, it is crucial to maintain it properly. In addition to cleaning it regularly, you should also check it for any signs of malfunctioning. A bad compressor can leave you sweltering during the summer heat. To detect whether your air conditioner is suffering from a damaged component, you can test it with a multimeter. First, place the positive probe of your multimeter on the AC compressor clutch connector terminal and the negative one on the battery post. If you don’t get any voltage, it means that there is a problem with the power supply to the compressor clutch coil.
