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

Conner Auto 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 Conner Auto 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.

Juan and Randy did a good job on my car. My car had some trouble and was sluggish but they fixed it right up. Jose always did a fantastic job on my car for years! I had a good experience with them and they got the job done at a reasonable price too. I am planning on taking other family member's car for service since it is hard to find a good mechanic. Thank you Jose, Juan and Randy

reviewiconGreat Mechanics
Car & Truck Care

I work for the State. Conner's was recommended to me and they have been nothing but fantastic servicing my State vehicle as well as my personal vehicles. Many times on short notice they squeeze me in. Just a bunch of great mechanics with even better attitudes towards customer satisfaction. Having been a former tool salesmen, I have met many mechanics, and these guys are tops...

Once again Conner's goes the extra mile, texting and talking me through some problems with my RV, educating me on how the electrical systems work and getting me back to functioning at full steam so my vacation could continue! Thanks Randy, you're the BEST!!
