How do I remove freon from my car AC unit?
I live in Florida and going without air conditioning in my car is almost unbearable. My mechanic friend told me that the freon in my AC unit might be stuck and I should remove it and refill it. I’m new to this type of maintenance. So how do I take the freon out of my car’s AC?

- Wear personal protective equipment before you remove the freon.
- Locate the low-pressure AC service port under the hood. To find it, use your owner’s manual, a schematic of your engine compartment, or search the back of the AC compressor. The low-pressure port is the smaller one of the two you’ll see.
- Use a wrench to close the low-pressure service valve.
- Attach a car AC recovery machine. You can buy one for about $300 to $500 or find an auto parts store or mechanic that will rent one. The recovery machine condenses the freon to vapor, which removes it from the AC system.
- Reopen the low-pressure port.
- Buy a can of freon and attach it to the low-pressure port.
- Turn the car on and run your AC.
- Press the plunger to release the freon into the system.
