Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
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 Inter Shop Inc, 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.

Mauricio at Inter Shop is the best shop steward I have ever worked with. He is on the spot identifying potential issues, while also sharing if they need immediate attention or can wait awhile if I need to. Intershop in Wilmington has fixed every issue we have without requiring any follow up. Awesome
Mauricio worked on my 2004 x-type and it has run smooth ever since. My wife used another shop but after having a unhappy experience, I suggested she take her 2006 mini to Inter Shop. They fixed her problem and she in now going to use them exclusively. I just bought a 2007 Mercedes S550, partly based on Mauricio because I know if there are any problems, he will look after me. I feel their prices are reasonable and knowledge impressive. It has become harder and harder to find good mechanics these days but I have hit the sweet spot with Inter Shop. Give them a try, you wont be disappointed.
