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 mechanics at Long Hill Auto Service, 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.

A few weeks back my wife was driving from PA to NYC by herself and started to have some car trouble. She called me from route 78 and I advised her to get off at the next exit and head to the closest repair shop. Thankfully it was Longhill Auto. At the end of their business day they got right on checking the car out, and were gracious with my wife who was having a very stressful experience. They were in touch with me every step of the way. Ultimately performed the necessary repairs and thoroughly test drove the car to give us peace of mind it was in good shape before making the hour plus drive out to pick it up. Would definitely recommend them and even going out of your way to work with them as it isn’t always easy to find a good shop with great people.

Long Hill Auto is the best auto service shop in the area, hands down. The staff is well trained and highly knowledgeable. Their facility is well organized and cared for, which shows how important it is for them to pay attention to details. Bob runs a great shop that can handle all of your automobile needs. They are friendly, affordable, and have a fast turnaround on their jobs. I don't think it can get much better than that.
