Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Mike's Performance Garage
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 Mike's Performance Garage, 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.

Our daughter was in Florida on vacation. Her car broke down and she had it towed to another shop that tried to charge her a small fortune because she was a young girl from out of town that didn't know any better. We had the car towed to Mike's instead. They worked their tails off to fix her car and get our girl back on the road for considerably less money. They did a great job, worked fast and for a great price. They definitely helped a worried mom from Michigan. I would ABSOLUTELY recommend Mike's to EVERYONE!! Thank you guys so very much for all you did!!!!
