Project C-10 Pulling a Vacuum and adding R134a Freon Pt. 33

Today we learn how to evacuate and pull a vacuum on automotive air conditioning (A/C) systems using R134a or R12 refrigerants. Discover why pulling a vacuum on an A/C system is crucial, how A/C systems work, and the components involved such as the A/C compressor, condenser, Receiver Drier, expansion valve, orifice tube, and evaporator. Also we install a trinary switch.
