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 West End Garage, 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.

    Just used West End Garage for the first time this week. I was VERY happy! Their prices were very reasonable and they kept me informed of the progress of the work. They were knowledgeable without being arrogant or condescending which is especially refreshing as a woman who understands nothing about vehicles. I have definitely found my go-to mechanic for any future needs. Highly recommend this place for anyone who needs service on their vehicles.

    I was quoted a price of over $1700 to have the A/C on my 2009 GMC Sierra repaired by a local large dealership. Budd at West End Garage said he would check it out and there was a good possibility he could fix it without having to replace the compressor. He replaced what he thought was wrong (after calling me and explaining what his plan was). He wound up fixing my A/C for a few dollars more than $300 (saving me more than $1400) The A/C now blows the coldest air it has since I can remember. Not only did they save me a ton of money, but were super nice and informative in the process. Thanks West End Garage.
