Replace Your Car's AC Thermal Expansion Valve or Orifice Tube

American Brake Centers Inc.

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 American Brake Centers 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.

American Brake Center installed new rotors and pads on my truck. My truck now stops very smoothly and with with no vibration. Scott and his team of mechanics are very good at what they do.. I'm very happy with the job they did. I will definitely go back for other mechanical work.

Scott and the crew at American Brake Centers did an excellent job finding the problem in my SUV and then fixing it. They didn't try to sell me unnecessary things. They told me what the problem was and then gave me options to fix it. I would highly recommend these guys.

Best place I have found to get car repairs. Honest, friendly, and knowledgeable staff. Always try to save me money instead of finding ways to charge more like some others. Scott is a great person to deal with. I really don't know how, but he is always cheerful and helpful.

Great service!! Always professional, courteous and informative. I have them do almost everything for my car and my whole family goes there as well. When you leave you'll know exactly what was wrong and what they did to it and the work will be done right.
