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.

Took my car in because it was making a noise that said, Hey, something's not right but I'm not telling you what. I rolled in on a Monday, explained the situation, and they got me on the schedule for the very next day zero drama, zero nonsense. Turns out it was the front driver's side wheel bearing, which, I now know, is kind of important. The guys working there are twins identical twins so I'm not sure which one I've been chatting with, but both are great so it really doesn't matter. Quick, honest, straight to the point. None of that you might also need a flux capacitor energy. Dropped the car off and by 11am it was DONE. Boom. When I came to pick it up, one of the twins (again, mystery twin) had already started the car and cranked the AC so it wasn't a sweat lodge on wheels when I got in. 10/10 thoughtful move. Highly recommend. I'll definitely be back (but hopefully not too soon ).

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.
