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 Gatti Automotive, 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.

First time using this shop. very impressed. Professional, knowledgeable. Diagnosed my problem quickly, repaired it at a very reasonable cost. This is my new repair shop. No more dealership service for me.

My car has been leaking for several years, I took it to several different auto repair shops including the dealership and no one could find or fix the leak. A friend recommended that I try Gatti Automotive, and I glad I did. They fix the leak in a few hours. I was highly impressed with their professionalism and how quick they repaired my car. I pleasantly surprise how clean and nice the waiting room was. I will be calling them back for future repairs and recommending them to others.
