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 East Coast Automotive Services, 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.

Automotive service and customer care done, right! I drive a 2013 and a 2007 automobiles. The vehicles have approximately 150,000 and 135,000 miles on them respectively. East Coast Automotive has done an excellent job of keeping the cars maintained and roadworthy. There have been the usual items that have needed service/repair typical to cars with as many miles as they have on them. With the cost of new automobiles as high as it is these days, I have complete faith in East Coast Automotive helping me keep both vehicles on the road for as long as possible. If you’re looking for a good automotive repair center that you can rely on try East Coast Automotive.
