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 Garage 47, 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.
Reviews
Best mechanic I’ve been to. My last visit they actually charged less than what was estimated because they were able to repair a part instead of replacing it. Great, honest work! Miles Caton, 07/26/2024 |
couldn't pin down a leak in my car, had it checked out and got a radiator replaced, they have a great system in which they take pictures of everything and give recommendations via text and emails, it was also nice to see that they confirmed prior work I did like, swapping out filters and such with pictures and didn't recommend something I didn't need like some places have. would definitely go back.

What a stellar spot.! I needed some work on my Rangers AC. Not only were they timely and good at what they do, they' talked to me like a normal person. Explaining, while not being condescending, how very refreshing. <3 While waiting in their clean waiting area, I got a text to a link showing me diagnostic outcomes, complete with photos, degrees of severity and pricing (which was very reasonable). I got to approve or decline any of them. Absolutely wonderful concept! It doesn't hurt that theyre handsome either ;) I really really like Garage 47! Magic Munson, 07/11/2024 |
