Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Accuracy Automotive Service and Repair
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 Accuracy Automotive Service and Repair, 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.

Fast, honest, and efficient service. I have never been treated better than I was at Accuracy Automotive. My car was having problems and they got me in the next day. Nic explained everything to me with respect. (Past places being a woman I have been talked too like a kid.) he gave me details on parts I needed with the cost and time if would take. I had a meeting that I had to get too and he also made sure my time was valued and that I was out of there on time. It was organized and clean as well. If you want to go to a place with integrity, go here!
