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 Avus Autosport, 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.

What our clients are saying about us
We have established longterm and stable partnerships with various clients thanks to our excellence in solving their automotive needs!
Trust in this industry is very rare, and reviews like this are normally always biased with people reviewing shops based only on personality of people working there and without knowing what goes into the actual work being done. When you see someone leave a five star review, how do you know that they know the work that has gone into the car? Usually people have no idea what shops do to their cars. In my case, my business is in the automotive industry and I deal with shops on a daily basis. I can say with absolute certainty that Avus Autosport is run by people that love cars, and treat my cars as if they were theirs. Their mechanics have the experience and in-depth knowledge around any of the BMW’s or Porsche’s that I’ve brought in, and only use the best vendors as I’ve used their vendors as well. All in all I can say that for any German or European car, Avus is the one shop that I can trust 100% to be friendly, yes, but to truly do the work in the right manor with the utmost care that I look for. Thank you guys for always taking care of any car that I bring you!!
I recently had my wife's BMW X2 serviced at Avus. Again, outstanding service with more than reasonable pricing. They let you know what your car needs and whether it's a needed critical repair or not. My BMW 430i just came out of the dealership warranty and I will now have it serviced here too. Andrew and company are the best.
