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 Turner Automotive, 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.

What our clients are saying about us
We have established longterm and stable partnerships with various clients thanks to our excellence in solving their automotive needs!
We first went to them when we moved from Rochester to Rainier. They were so very professional and did not beat around the bush. Come ten years later we moved to Tumwater and I had problems with my car. I could not go anywhere else had to drive all the way back to Rainier to get my car taken care of. Kris kept my husband up-to date as to what needed to be done and before they did anything and gave him a quote as to how much it would cost. Now for the best part.Took it in on Monday on Wednesday my car was ready to go. Thank you so much for your great work and always having time to fix my car.
