Have you ever flipped on your car AC on a hot South Riding day and asked yourself. “Does Car AC use gas?” Well, the answer is yes!

How Does Car AC Work?

Car AC actually is quite similar in every vehicle on the roads of Centerville and Chantilly. The AC system is operated by a high-pressure gas called refrigerant. Regardless of which type of vehicle you drive, these parts are the same:

  • Compressor — Turns the refrigerant into a fluid, which then flows through a line to the condenser. 
  • Condenser — takes the heat out of the refrigerant and sends it to the expansion valve or orifice tube. 
  • Expansion valve or orifice tube — returns the refrigerant to its original gaseous state and sends it over to the receiver/drier or accumulator. 
  • Receiver/drier or accumulator —takes the moisture out of the refrigerant and sends it to the evaporator. 
  • Evaporator — takes the heat out of the air passing through its core and sends it into the refrigerant, resulting in cold air flowing past the evaporator.
