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 Velocity Automotive Service, 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 Customers Are Saying
Great place, awesome prices and they gave me a free inspection when I didn't make any purchases at all! Awesome local shop, way better then the chains and full synthetic is cheaper then the dealers!
Efficient, clean, courteous and they don't over sell. Support this local small business and you won't be disappointed. :)
Needed to have my brakes looked at after being told i needed to have them replaced right away by another business. After a few minutes they actually told me I wasn't in dire need of having them replaced. I opted to go ahead and have them done just because the squealing was annoying. But I have to say, I appreciate the honesty. They have a nice waiting area as well although I was only there for about 45 minutes. They offered the best prices after calling around and their professionalism was outstanding. Thanks guys.
I can't believe no one has reviewed this wonderful place yet!! I went here for some A/C repairs and was so glad I did!! They were more than helpful getting me in right away and the customer service was exceptional! The waiting area is well decorated and inviting(unlike most service shops) also the staff was So friendly! I was asked more than once if I wanted a bottle of water or anything to drink:) The guys were beyond helpful explaining what was being done and trying to get my car repaired quickly so I could be on my way! My A/C is still blowing cold and it was a pleasant service experience. I Definitely recommend Velocity!
