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


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 Argos European Car Care, 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.

reviewiconYou are in great hands if you own an European vehicle with Argos!
European & Import Vehicle Repair, near Jacksonville, FL

The people here take great care of my older (2016) CLA 250 for all my maintenances. They always let me know if they notice anything suspicious with pictures but never once made me feel pressured to do anything I didn't want to do. I love how convenient it is to drop off my car and look at the quote ahead of time and prepay and authorize exactly what I need taken care of. The people are always friendly and ensures to communicate well and thoroughly. I can always call to make an appointment and they take me right away. You are in great hands if you own an European vehicle on the north side with Argos !
