Replace Your Car's AC Thermal Expansion Valve or Orifice Tube

Your car or truck's AC system is under extreme pressure and the thermal expansion valve or orifice tube monitors the amount of pressure and the temperature of your A/C system. It calculates the precise amount of refrigerant that can safely go into the evaporator. A failing expansion valve or orifice tube often causes a vehicle's air conditioner to blow hot air.

Replace or Repair

  • Expansion Valves: Too much refrigerant causes your evaporator to get too cold whereas too little refrigerant would result in inadequate cooling. The expansion valve is a complex valve that regulates refrigerant flow. This process of metering the refrigerant adjusts the flow according to the temperature of the refrigerant in the evaporator coil. Talk to one of the pro mechanics at King's Auto Care, as this part can be replaced on its own and does not require the entire replacement of the AC assembly.
  • Orifice Tubes: Unlike the expansion valve, the orifice tube is a simple fixed device with no moving parts. It therefore cannot vary the flow of refrigerant into the evaporator, but rather causes a permanent restriction in the system. However, like the expansion valve the orifice tube regulates refrigerant flow through the system and filters debris which may come through in its screen. Often fixing a "bad orifice tube" requires replacing the entire evaporator assembly.

    These guys are fantastic. We had car troubles while on vacation, and they went out of their way to get the car fixed within a day so we didn't have to drive to LA in a rental and then come back for our car later. Friendly, honest, caring and expert. I can't recommend them highly enough.

    Terrific garage, really helped us out of a bind. We had car troubles on the 101, limped to this garage. They had us back on the road in a jiffy! Reasonable prices and honest people. A+

    Kings auto care was absolutely great. I highly recommend this place for repairs. Jim was great, very professional and kept me up to date with what was going on with my car. When I need repairs again I'll be going here and asking for Jim. Thank you!

    Kings Auto Care was by far the BEST experience I have had by a mechanic. Jim is the owner and sole worker at his shop. Jim is very honest and more affordable than any other mechanic. He is very thorough and spends time explaining exactly what is being done. Additionally, he will not try to upsell any products or services that are not required. I live down in SLO and will drive all the way to Paso to Kings Auto Care every time!!
