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

Long Hill Auto Service


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.

Got a flat on the way home from work, called Long Hill Auto Service just before they closed for the day and they squeezed me in, two tires mounted and balanced in under 20 minutes. I would have been stuck the next morning for work, so many thanks to these great, helpful guys!

Long Hill Auto is BY FAR the best car repair experience I've ever had- and I've had MANY...This shop is the classiest act going! You will not find an Owner like Bob who takes more pride in his business and his work. As if the incredible service wasn't enough, the prices for all work done were fair and reasonable. Save your money at the dealership and take your car or truck somewhere much better, Long Hill. I will not be taking my car anywhere else ever again. From regular maintenance, to pesky issues, Bob and the team at Long Hill will always have my business for as long as I'm driving!
