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 X-Pert Automotive, 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.

    I've been a customer for about 10 years. I trust X-pert Automotive. They are honest. When a technician finds an unexpected repair issue, they always consult with me about what's wrong and how much it will cost to fix it. I recommend X_Pert Automotive.

    First time customer. Diagnostic test performed first and accurately pinpointed repairs needed to turbo charger control module. Great communication to me as to issues and cost. Repairs were prompt and fair (I checked). Work timeline was what they told me and cost was as quoted. Excellent service all around. I have finally found a maintenance shop I can rely on and will be back for all of my vehicle service needs...
