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 Folsom Autotech, 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.

These mechanics fix your vehicle and stand behind their work. They bent over backwards to accommodate me and my schedule. They are located on an easily accessible corner with plenty of parking. The manager, Ron, and owner, Jim, were professional and courteous at all times with such great smiles and information as well as many years of experience and knowledge. A real find and I will continue to use them for my mechanical needs.
Folsom Autotech has been my go-to garage for over 15 years. I asked the guys I work with where they'd send their wife or daughter for car repairs and the resounding recommendations was Folsom Autotech. They were right, this is MY garage and I don't want or trust anyone else to work on our cars!
Excellent service! Helpful and fast!
