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 360 Auto Repair Services, 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.

What People Say About Us
Ladies, if you've ever had issues with condescending shops before, this is the shop to go to instead! These men are incredibly courteous, explain things clearly, charge fair prices, and do incredible work. I had a $1000+ repair I had to do on my car, and they're the only shop I'd trust because I knew it would get done well, and probably cheaper than anyone else, which makes it well worth the cost. I've been going to them for years and will continue going as long as I live in Antioch. My car is so important to me as a broke 20-something commuter, and they're the only place I go. I'd give 3000/5 stars if I could :)
They are so awesome excellent customer service
