Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Spatig Bros Auto
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 Spatig Bros Auto, 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.

Spatig Bros towed my van for me after I hit a deer. Because I was an hour from home, I had nobody there to pick me up. He took me to his shop where he offered me coffee, water and a soft chair then proceeded to do his work. He checked on me every 5 minutes or so just to make sure I was okay and then spent several minutes going over the damage to my car with me. He was incredibly kind both at the scene and at the shop and made a really hard morning that much easier. Great customer service!
Great people, great service. You'll never find anyone better.
My truck broke down today heading through mink creek. The owner came and took care of us. He was very professional and extremely nice. The ride back in his truck was comfortable. He has a great personality that definitely helps get you in a better mood after a bad day. Rates were very good too. I would definitely recommend. But I hope I never need him again.
