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 & D Automotive and Diesel, 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.

What Our Customers Are Saying
Sprinter problems! This is the place to go. Why wait two months for the MB dealer when D&D will get ya sorted in days. Called em min cross country trip from Florida ton Idaho on a Tuesday and the had me sorted before brunch Wednesday. Dealer stated they could take a look in 6 weeks - a common issue dealerships. But not double D! They open super early, have professional technicians, are super friendly and a fraction of the cost of the dealership. Thanks D&D for keepin the wheels turning!

I highly recommend this small but mighty automotive shop. We have taken all of our family vehicles to D & D for several years now. They go way above and beyond. I had a question on my daughters 2014 Ford Focus transmission and Cody called several places to research my options for me, to see if it was worth fixing or not. Also, they never push other services that are not necessary. They truly are honest group of guys. Thanks again Cody!
