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

LT Foreign Car Service German & Japanese Auto Repair

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 LT Foreign Car Service German & Japanese Auto Repair, 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.

LT, has been my go to mechanic for several years now. He's honest, trustworthy and his work is excellent. He keeps my 2010 Lexus Rx350, 140k+ miles running nicely. Brakes, shocks, sensor replacement and an electrical issue. He's even taken time out of his busy schedule to answer questions and offer advice about my car when I was traveling. Thank you! Thank you LT!
