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

Grand Motorsports and Service, Inc.

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 Grand Motorsports and Service, Inc., 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.

Testimonials

, 06/19/2021
The guys in this shop know what they are doing and I trust them. This was the second time I've gone to Grand Motorsports, and I will continue taking my cars there. The first time I went there, they fixed a plastic guard on the front of my van and didn't even charge me! Another auto shop in town told me it wasn't repairable and they wanted to charge me $900 to replace it! That's when I knew I had found the right place in Grand Motorsports. Honest, knowledgeable, friendly, customer-service oriented, and very convenient location. Five stars for sure.
