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 D&L Auto 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.

Always did business with D&l until I moved to Florida. After 2 years away I came back visiting and developed problems with my truck. Received many ideas of what was wrong, but held out to get D&I to fix it. They fit me in and solved the problems, none of which was suggested from other shops. Very honest and thorough! Reasonably priced! If you want the best, you gotta go here!

Went in today for an inspection. Needed new rear brakes to pass (which was not a big suprise to me). Asked if they would be able to do it today. They said yes and it would be about 2 hours. Asked how long do you think it will take so i can let my boss know because I work from home. The owner offered to let me borrow his personal truck to go home, so I could work and come back when it was finished. Great customer service and a fair price. Will definitely be returning for future needs.
