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 A & B Automotive Inc., 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 husband and I are new to the Matthews area and found A&B while looking for a place to get our cars inspected. The people who work here are so kind and helpful, the prices are fair, and neither of us has ever had a bad experience. We take our cars here for everything, including a recent tire plug which they did for free. Don't hesitate to go here for honest, hard-working service and friendly staff!

I have used this shop for over 20 years. Honesty and craftsmanship have always been their standard. Fix only what is broken at a reasonable price. I recently had to take my sons car to the dealer. The dealer reminded me why I don't take my cars to the dealer after the free oil changes run out. not a good experience. I prefer to do business with a small business that gives value for money.
