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

Landmark Auto Group


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 Landmark Auto Group, 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.

Fantastic experience today! I had an appointment at 3:30 and I swear they were working on my car by 3:35. Oil change and emissions done in an hour at a reasonable price. They didn't take advantage of the fact that I left my emissions till the end of the month and really needed my car done. They were professional and very inviting. Will definitely be back.

Excellent service. I took my Audi Q5 for brake work and I am very happy customer. They completed the job in 2 hours with reasonable price and complete professionalism. They explained things to me very clearly, the various options and what needs to be done. I felt they were honest and not pushing unnecessary repairs as most of repair shops do. I Fully recommend this place.
