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

Lukoil of Lawrenceville


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 Lukoil of Lawrenceville, 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've been taking my two family cars to this shop for the last three years and have always had good service. Jeff is an excellent mechanic and is honest, thorough and reliable in everything he does, which is the most important part for me. I've even had an instance where the repair went bad and he fixed everything at no charge and apologized for the inconvenience. I always receive a call when the car is ready; and, since the gas station is open late, I can pick up the car at just about any time. Labor rate and parts costs are about average for the area, and its no problem if you want to bring your own parts to them. Highly recommended.

The best in car care! Honest, trustworthy, thorough, very professional, friendly, reliable...I cannot say enough to capture the best service and people in car care service! Thank you, Jeff, Gus, et al.
