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 Retro Auto Works, 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.

    Although Retro Auto Works has only been open for a short period of time I have already used them twice. Once to get new breaks and another to get my shocks replaced. Justin was professional, fair, and had my car ready quickly. I'm very pleased and would recommend anyone to go to Retro. I will definitely continue to use them for all my future services!

    I went here because my alternator was messed up and he found other things that went wrong that I thought was already fixed by another mechanic. Shane, the owner, had everything done the next day. Very professional, clean work area, and parts with warranties. I'd recommend him anytime! Thanks Shane!

    For the first time in over 20 years I was responsible for getting my vehicle inspected. My goal was to discontinue going to the dealer for service. After reading the views for Retro Auto Works I decided to give them a try. I Had my car inspected and services recommended by Honda. I was very pleased with my experience.
