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

Dependable Automotive Center


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 Dependable Automotive Center, 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.

Ok so my SUV broke down. I brought it to this guy hopeless that it could be fixed for under $500. But he did it!!!! He fixed my Beauty and made her all better again for allot less than $500. He kept in contact with me during the whole process and let me know everything he was going to do before he did it. He was very professional and super nice. I'm so grateful to him for fixing my car and getting me on my way. I would recommend you go to him for any car repairs you might need. He provides affordable service for fair prices in a timely manner. Thank you so much for saving my car.
