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 Lakeside Certified Auto, 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 been having my car worked on there for quite a few years now. My son's child hood friend work there. He a 5 star mechanic. The business there is top notch. The price is very good. I come all the way from the Westside of Cleveland to Willoughby Ohio because it's hard to find a good mechanic shop.

    This was my first visit to this neighborhood business and we were very impressed. They checked my concerns, found nothing wrong, and we weren't charged. What I needed would have required a fair amount of time and effort ... no charge! We will definitely return for any service needs for our 2 cars. Thank you Lakeside Auto.
