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 Das Performance, 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.

Das Performance and EAG Performance (shout out to Moe) are the only two places you should ever take your car into if you live in Fredericksburg or if you planned on making a trip to here. Everyone at Das Performance from the front office to the hard working mechanics in the garage are all excellent from top to bottom. They will let you bring your own oil and oil filter for your oil change and they cost a nominal fee for labor (and they deserve more). The same can be said for other tasks like brake pads and rotors replacement as I was able to bring my own parts for my Mercedes and, again, they charged a simple labor fee. Overall I highly recommend Das Performance and want to thank all of the hard working people behind this excellent shop 100%. TLDR You can trust your car here at Das Performance. Thank you very much.
