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

Santa Ana Auto Care


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 Santa Ana Auto Care, 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.

First let me say that I will never go to any place besides Santa Ana Auto Care. I spent weeks trying to figure out who I was going to take my car to for preventative maintenance. Brake (F/R), Drive belts, Throttle body service etc.. The price was better than anywhere else and the work was done expertly and quickly. Maher and Muhammad were absolutely amazing. Now here is why I will never go anywhere else. The drive belts were missed. They did a bunch of work. Easy to miss it on the list I had. I reached out and let them know it was not on the bill. They reached back out quickly and we got it taken care of with NO inconvenience to me. Maher and Muhammad were on it. You don't get quality of work AND customer service like this anywhere else. I appreciate them greatly and will take any work needing done to them. Thank you for everything.
