Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
G & L Automotive II
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 G & L Automotive II, 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.

Just wow! Great honest service at a reasonable price. I can't complain. I first went in because I thought I needed a transmission, I really didn't, my cv axle broke. so they replaced that. I was very satisfied, any other place would of lied and said I really do need a transmission. Then I had a different problem with my car a week later, one of the studs in my wheel hub just came loose. I thought it was going to be a costly repair trying to remove the wheel with a lug nit that just keeps spinning, I was wrong! It was removed and replaced in about an hour and a half! My new go to mechanic from now on!
