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

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

 103 Verified Review(s)

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 Val & Mike's Beach Cities 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.

what our customers say

They were very helpful. Excellent service. They found some additional needed repairs when they took the car apart but they only charged me for the additional parts but no additional labor. I was very happy with that!

I had an amazing experience. Val was so sweet and extremely helpful. I recently moved to CA from NC and had to get a safety and emissions inspection done and Val went above and beyond to get me scheduled and get my inspection completed. Make sure to go to Val and Mike's Auto Repair for any of your vehicle needs. You'll be so happy you did!
