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 Vince's 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.

My daughter's car broke down on the freeway and the Triple AAA tow truck driver suggested Vince's Automotive. I dealt with Edward on the phone and he gave me a update on my car almost immediately. I had put a new transmission in two years ago and it was out of warranty four months ago. He told me that his shop would honor the warranty even though the warranty was expired and that the shop that put the transmission in should too Armed with that information I talked to my previous mechanic and we worked out a deal. Edward is an honest guy, I was surprised that he wasn't the owner of the shop! He is one of a kind and I will be taking all four of our cars there as ling as he is there. This guy is one in a million! He even handed the towing service so I didn't have to come in. You don't get customer service like this anymore.
