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

Zeigler Transmission & Auto Repair Inc.


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 Zeigler Transmission & Auto Repair 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.

My truck suffered a seal failure on my way to Pendleton and I was in town for only one weekday so I had to get it fixed in one day. I won the no wait lottery and Zeiglers was able to repair two seals on my truck on a Friday with no appointment. I am very pleased with the service I received and the cost was reasonable.

Absolutely 5 stars. I have been going to these guys for close to 15 years with 5 different vehicles, and have yet to have a misdiagnosis or be overcharged, and Kris is just a good, solid human being. I was nervous about buying a car brand where the nearest dealer was over an hour away, but I have learned to be confident in Ziegler's abilities to handle what I throw at them.

Chris worked overtime on my transmission to get it up to speed after putting in a rebuilt transmission. I appreciate the honesty and willingness to go the extra mile to get it taken care of. I would not hesitate to take my car there again.
