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 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.

I am a returning customer and will continue to return for any future vehicle issues! We had a noise in our van that would appear only at a very specific moment during acceleration, but it could be heard by anyone in a two-block radius. Instead of just throwing time and money at parts, they took their time to look at all of the potential causes. It took a little bit of time, but ultimately were able to fix the issue at a fraction of the price that we would have spent if we went to the original shop that gave us a quote. Josh, Rick, and the rest of the team are trustworthy and stand by their work. I would highly recommend them to anyone needing any automotive work.
