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.

I have used Long Hill Auto for over 35 years and I wouldn't go anywhere else! Owner Bob Arlotta genuinely cares about his customers and takes pride in his business. There is no forcing of repairs, just cautionary suggestions based on assessment of your vehicle. I don't know about you, but I'd rather be aware that something needs to be done before rather than find out the hard way after. If you care about the safety of yourself/your passengers, want an honest assessment of your vehicle, AND the best maintenance and repairs, go to Long Hill Auto. You won't regret it!

This is the place to take your car when an issue arises. Expert staff, very friendly, great prices, and high-quality work. It's no surprise they have been there 30+ years. I think I found a new auto repair shop!
