Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Market Street Used Tires & Auto Service
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 Market Street Used Tires & Auto Service, 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.

So I had the worst day ever. Was told by one shop I needed $1500 dollars worth of work on the front end of my truck. Dealer want almost double. Stopped by this shop because I passed it. The guy at the front desk was so awesome. Took the time to dig on the wed for what I needed. 3 hours later, and $ 380 later I'm golden. Shane you are the man! Your crew is the best. Everyone that worked on it let me know what the deal was. By the way the family that owns this spot is just beautiful. Love this place! Highly recommended.
