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 Leo's Auto Care, 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.

Reviews

I went in as soon as they opened to get my front brake pads replaced. They completed the job in a timely manner, and I was extremely satisfied with their service. I'd feel comfortable going back to them for any maintenance and service needs.

Leo's Auto Care was such a great experience. I was assisted by Jaoquin upon arrival. I needed my brakes done and 2 tires and Joaquin was not only knowledgeable on what could be wrong but also friendly and welcoming! The entire shop was this way as well. Juan & Joaquin communicated thoroughly through the entire process with me and kept checking in. This is my new go to shop & it should be yours too! You won't regret it.
