If freon is causing any sort of issue with your car’s AC system, you can remove excess freon using some tools and an AC recovery machine. Follow our step-by-step guide below.
Freon is not simply used for air condition units inside personal vehicles. Over the years, the gas has also been used in chest and upright freezers. Many commercial and industrial appliances use freon for the transportation and cold storage in large warehouses. Dehumidifiers use this gas as well.
Freon works due to a system of coils and compressors inside one’s AC unit. When compressed, the gas gets very hot. When freon moves through the coils, though, it creates a very cool liquid. This is a constant cycle for your AC unit in your personal vehicle. When coolant leaks, the AC will cease blowing out cold air, making a repair necessary, especially in the warmer summer months.
Finding out if freon is being used is not a complicated task. By looking at your air conditioner’s nameplate, you should be able to tell whether or not freon is in use. The nameplate will provide information about the unit, which includes electrical ratings and safety certifications. If you cannot find the nameplate or read the information provided on it, contact the manufacturer of the unit.
Steps To Remove Freon From Your Car’s AC
Follow these steps to properly and efficiently remove any excess freon from your vehicle’s air conditioner:
- Start by putting on some personal protective equipment prior to removing the freon.
- Find the low-pressure AC service port beneath your hood.
- To locate the port, use your owner’s manual or search the back of the AC compressor.
- The low-pressure port will be the smaller of the two you will see.
- Use a wrench in order to close the low-pressure service valve.
- Attach a car AC recovery machine at this time.
- The recovery machine can condense the freon to vapor, removing it from the AC system altogether.
- Next, reopen the low-pressure port.
- Purchase a new can of freon and attach it to the low-pressure port.
- Turn your vehicle on and run the AC.
- Press the plunger in order to release the freon into the system.
