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 CARZ- Complete Auto Repair Zone, 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.

    Stop by here one day to have some minor tire work done. Collin was super friendly, helped me on the spot, and didn't even charge me. I'll be back when something goes wrong on my vehicle.

    CARZ was recommended to me by my USAA auto insurance when my check engine light came on during a road trip. I was highly impressed with the courtesy, professionalism, and the thorough explanation of the issue with my car. Every customer who walked in the door was greeted by name by the staff, and it was clear that staff had taken the time to build solid relationships with their customers. Attached to the wall in the clean waiting area were several cards and letters from customers sharing their appreciation for excellent work. I only wish this company was located closer to my home! I wish to share my appreciation to CARZ for assisting me, and for giving me the comfort in knowing that I could continue my journey safely.
