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 KPS Princeton Garage, 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.

Testimonials

, 06/23/2022
I went in for a severely flattened tire. KPS Princeton Garage not only found the rather specialized tire, mounted it with balancing, etc. and road tested, they also alerted me to another problem. They suggested that I should go to my dealer with this problem, since it was likely to be covered under warranty. I did, and it was! So they saved me a lot of money by not doing the work themselves. Many thanks! This year I had another flat tire (Chevrolet does not provide or even sell a spare for the Volt). KPS Princeton Garage not only fixed the tire, but told me that the dealer's advice that I needed new tires was greatly premature. More money saved.
