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

CT Automotive and Cycle


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 CT Automotive and Cycle, 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.

Thomas and the staff at CT automotive are top notch. We take both our cars there because Thomas is an honest guy with a lot of expertise and he's going to give it to you straight. They worked on my Subaru recently and they did a great job. They told me what to expect going forward and had kept me updated throughout the process. I highly recommend CT Auto for your cars needs. Thanks Thomas, Ashley and everyone over there. You guys are awesome!

I've been coming to CT Automotive for about 3 months now. In that time, I've had about 4 repairs done ranging from putting on headlights and side mirror to radiator service. Mike at the front has always been really nice and thorough when explaining what my car needs. They also helped me with a ride to my house while I waited for my car. Overall, the cost of services is a bit on the pricey side if you choose to use their parts, but they will also install customer provided parts, which is a huge plus. Service is always friendly and the work done on my car has always been reliable! CT Automotive is always my first choice for car repairs
