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 technicians at CARZ, 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.

I have been using Carz in Horseshoe since November 2022. From that first appointment, I knew this was where I wanted to bring my car for any repairs and maintenance that I need. Andrew always listens to my concerns about my car and he as well as his employees go above and beyond to evaluate my car issues. I have had to stop by on two different occasions for an immediate concern and even though they are always very busy, Andrew made sure my car was looked at and safe for me to continue driving. I can?t say enough about his kindness and the expertise and courtesy of all of his employees. They are truly amazing and exemplify what real customer service and caring is all about. This is definitely a trustworthy auto repair shop. I recommend them highly, and wish I could give them more than five stars!

Stop by here one day to have some minor tire work done. Collin was super friendly, helped me on the spot, and didn't even charge me. I'll be back when something goes wrong on my vehicle.
