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.

Great shop, nice guys. Got my HPDE inspection done quickly and thoroughly.
I took my European vehicle to them for the first time several months ago & they did a major job: replaced the water pump, "programed" a new battery someone else installed in my vehicle & checked the car overall. A few months have passed and my vehicle runs like new! My most recent visit a couple days ago from the time of this post was for an oil change. I was pleasantly surprised that they gave me a $25 discount on the oil change! According to their website, they are partners with several companies/groups. I found them on Beemer World. Let's just say, I'm planning to take another car to them to have a check engine light diagnostic test performed. I will let you know how that works out!
Top-notch shop. Top-notch service. Respectful and knowledgeable. I couldn't ask for anything better.
