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 Victor's Automotive Center, 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.

    Victor at Victor's Automotive should occupy the entire block he is on. He is two things you can't find in the same place in So. Cal. He is honest and he is reasonable. He is also VERY GOOD at what he does but those other two things are SO important that you should try his shop. One time and you'll never go anywhere else.

    What a breath of fresh air! Real people who are actually in the business of taking care of your needs, and not just trying to make as much as they can off of you. Victor asked me how much are you looking to spend? He then told me what items he would recommend first to make sure that we get the most important things done. What a great business! I recommend anybody that wants honest great work and service come here.
