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 Auto Logic, 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.

Testimonials

This place is amazing! My car had the check engine light turn on, and we brought it here to see what was going on. Turns out it was a faulty gas cap. They did the code check for free, and told us straightforward that it would be better to get the gas cap replaced from the dealership directly since it will cause less issues down the line, rather than getting one from them. I really appreciate their honesty when most car places would've just tried to get money out of us. I am so impressed with this interaction and will definitely be returning whenever I need any car services in the future.
