How to Add Freon to a Car Air Conditioner

142

When your car’s air conditioner doesn’t seem to be blowing cold air anymore, you may need to add Freon to the air conditioning system. Mechanics can charge hundreds of dollars to do this, but you can do it for much less if you know how. Learn how to add Freon to a car air conditioner by following these steps.

Step 1

Attach the recharging hoses to your system. The hoses from the gauges attach to the compressor of your air conditioning system. Attach the shorter hose to the can of Freon.

Step 2

Open the valve on the can for several seconds to purge the air from the system. Tighten the hose connection again and close the valve.
