Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Automotive Technology Solutions
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 Automotive Technology Solutions, 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.

The owner is always friendly and fair. The work is on spot. I have never left this garage feeling bad about the work, price, or experience. The location is also very convenient. My car has needed very few repairs over it's 200000 plus miles....it may be because of good service.
Fantastic service and great owners, Both Cassandra and Aaron were incredibly nice people. Aaron found out what was wrong with my car and Cassandra helped me find an affordable part to fix the issue. Highly recommend stopping by ATS for a good job done quick!
