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 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.

Reviews

I was referred by a tech at Jiffy Lube due to an issue with my car (long story short, it looks like the fellas at Walmart who changed my oil last didn't know what to do with my oil filter cover and it was really, really stripped and stuck on), and the team at CT Automotive & Cycle really did me a solid. They got me in right away, found the parts, and they were also incredibly kind, helpful, honest, and good (despite being down a tech!). I come from a car family and I can say these are the kinds of guys you can trust, who are knowledgeable, and who want to help you. I know I'll be willing to drive to the opposite side of town just to stick with them next time.
