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

Larry Estes Body Shop

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 Larry Estes Body Shop, 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.

This company is very customer service oriented. They believe that they work for the customer and not the insurance company. I would recommend them for anyone who needs body work done.

I have used Larry Estes body shop four times over the last 3 years. I have always found them to be very good in regards to the work on my cars. They are also very professional. They have fixed a Buick, Lexus, BMW and recently a Mini. All come out looking and driving great! It is no fun to wreck a car, but I am glad these folks are around to fix them!

Wow! My Ford Expedition looks brand new! I have no idea what Estes Body Shop did to make the vehicle new again. I took it in to get the rear bumper repaired and repainted. I was not expecting the entire vehicle to be so sparkling-new. I would love to know how they washed it. The job was finished within the time frame they promised and I highly recommend them to anyone who needs auto body work!
