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

 89 Verified Review(s)

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 Familia Automotive, 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.

what our customers say

Found these guys after a previous mechanic misdiagnosed my issue. They fixed my van in just a few hours. They were kind, professional and fast. After I drove off, my van was driving so much better. Definitely would trust them to continue working on my van.

Went in to have my brakes and rotors replaced, they gave me a complimentary inspection and a reasonable estimate (another shop quoted me almost $200 more). As a lady who knows little to nothing about cars, shops can be intimidating, and at their worst, exploitative of your lack of knowledge. I felt very comfortable in this shop, the owner was exceptionally friendly, informative, and fair. Will most definitely be returning for my future repair needs and spreading the word to friends and family about this new business. Give them your support!!!

I can just truly say. I was well pleased with the service I got bringing my car here! The service was absolutely on point. The owner was very nice and friendly and took really good care of me. He made sure he kept up with me about everything with my car. I love how they are very business structured. I would definitely recommend them to any. If you ever need your whip fixed take it down there. They'll get you right! :)
