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

Northwest Allpro Auto Clinic

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 Northwest Allpro Auto Clinic, 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 Are Saying

If I could only rate them higher, I would. Pat (owner/operator) went above and beyond for me when I had a pretty traumatic breakdown of one vehicle, and another ran off the road. Not only was his work prompt, excellent, and affordable, he went FAR ABOVE AND BEYOND what could be expected of him when dealing with my insurance company. Over the course of several months of the insurance company losing paperwork and reciepts, even after I had paid him cash out of pocket, Pat went to bat for me and resent and re-emailed everything i requested of him to make sure I got paid. He's got my business for life and I would recommend anyone to him.
