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 Vic's Bimmer Shop, 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.

    First time at Vic's, it was a positive experience. The staff was friendly and competent. Everything went like clockwork (in todays world how many times can you say that) and my vehicle is running good. Looks like I won't be going back to the BMW dealership for repairs

    Had a strange noise coming from under the console that I couldn't diagnose. They found that the right side parking brake cable clamp was broken causing the cable to at times hit the drive shaft. Crazy. Glad they found it and fixed it so easily! Also, Vic's sends you an email with photos and videos of their assessment for your review before beginning work. This is great! I wish every repair shop did this.
