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

JN Automotive 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 JN Automotive 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.

Honest and affordable automotive repair and body shop with good customer service. I've had many bad experiences with unscrupulous mechanics and dealerships and it’s a relief to have found a capable and honest shop in the neighborhood. They take time to explain what’s wrong and provide affordable options. They have recently expanded their shop and they now do auto body work. And that was timely since I needed some body work last week and they did an excellent job fixing the ding and painting with clear coat.
