Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Sevy's Auto Repair
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 Sevy's Auto Repair, 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.

Having owned a business in a competitive market for over 30 years, you succeed or fail by your workmanship and your customer service. Sevy's gets an A+ from me! The engine in my 2004 Ford Explorer needed costly repairs, after considering a used engine, John recommended I consider a rebuilt engine from Jasper. With a 3 year or 100,000 mile warranty it was an easy decision. Sevy's mechanics are great! Had my Explorer back in a week. Had a minor problem, Sevy's took care of it immediately. Having worked on my own cars and motorcycles, I was impressed by the quality workmanship. Christy, John, and Tom are the best up front, and the service is great in the shop! I will recommend Sevy's to my friends and family. In fact I already have!
