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

Mike's Auto Service

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 Mike's Auto Service, 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

, 09/22/2019
I came to have my vehicle fixed Mike's out of a recommendation from a friend/coworker of mine. I just picked up my truck and it's running great. Working with Mike and his crew was hands down the best automotive service experience I've ever had. They are honest and trustworthy. This is the second time they've fixed a vehicle of mine. They've never tried to sell me an unnecessary service, and have provided me with honest guidance regarding my vehicle service needs. I wouldn't hesitate for a second to recommend them to my mom or daughter. Big thanks to Mike and the crew. I'll definitely be back.
