Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Sharon Woods Auto Care
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 Sharon Woods Auto Care, 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.

My mechanic was very welcoming, allowed me to sit in my OWN vehicle while he took a service drive to diagnose my vehicles problem, demonstrated transparency, and fixed the one problem that mechanics from other shops overlooked. The service was very affordable and swift to fix my issue. I highly recommend Sharon Woods Auto Care to anyone who needs their vehicle professionally, and honestly serviced.
