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 A & B Automotive 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.

They did what they said they were going to do in the time they said they were going to do it. They are extremely polite, and very experienced. My Yukon drives fantastic now. There's no question I would refer a friend or family member. There were no surprises when I picked my car up with additional cost, the estimate they gave me was exactly the final charge. The ONLY reason I took one star off is because there was a dirty print on my steering wheel and smudge on my driver side door panel. That's minor, but it's important to me. I am 100% sure if I pointed it out to them they would've taken care of it, but I was in a hurry and I could clean it myself.

I recently had my Odyssey's timing belt replaced at A & B garage, and I couldn't be happier with the service I received. From the moment I walked in, Rachel went above and beyond to ensure a smooth and pleasant experience. She even took the time to help me check the previous timing belt service guarantee, which was incredibly helpful. The entire team at the garage was professional, and the work on my car was done efficiently and with great attention to detail. I highly recommend this garage for their outstanding service and a special shout-out to Rachel for her exceptional customer care.
