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

Accu Auto Care LLC


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 Accu Auto Care LLC, 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.

I had a serpentine belt that was starting to shred and needed it replaced before I had to make a long drive. I came to Accu Care and Eugene dropped everything and got it replaced all within an hour. That’s GREAT customer service on such a short notice on an obvious busy day for him and his employees. Thanks AccuCare!!!

I would highly recommend Accu Auto Care for all your maintenance and repair needs. Wonderful customer service! I appreciated the ease of making an appointment, the email appointment reminders and day of service phone and email updates. Eugene's easy to understand explanation of what was wrong with my vehicle and fair estimated costs made this a stress-free experience. Also, the photo his technician provided will come in handy to show the dealership I have to use for a warranty covered power train repair. Many thanks to Eugene and his technician for making this the best auto repair experience I have ever had!
