How to remove refrigerant from car ac?

Best Answers

Disconnect the machine by closing the valves on the service hoses and removing them from the service ports on the vehicle. Early machines designed to handle R-12 (Freon) refrigerant are required to have shut off valves on the hose. read more

Freon has to be in a vacuum and to do this you need a evacuating pump. My advice here is have it done at a shop where it will capture the freon, make the repair and then evacuate the system and reinstall your freon. read more
