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 Hud's 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.

What Our Customers Are Saying
Honesty and integrity. Actually didn’t have work done because they analyzed my vehicle and realized it was a tire problem. Didn’t even charge me. Because they were honest and told me the problem without charging, I will be back with all my vehicles.

I've been going to Hud's for several years and they have worked on multiple cars of mine. I've been having persistent issues with my current vehicle, with the AC, and the check engine light kept coming on. It was taken somewhere else (not by me) multiple times and had a few very expensive bandaids slapped on it. Recently, the light came back on, so I took the car to Huds. Their prices are very reasonable and they're kind people who will work with you. As a single woman, this is incredibly important to me. I drove off, and the next day the light came back on so I called Huds. They took the car back in and replaced another part, no extra charge. I appreciate their hard work, honesty, and integrity. Huds actually fixes the problem, not the symptoms.

Excellent and friendly service! Said it would be 2-3 days but we got it back next day! We were met with a smile and listened to. They fixed an issue that was caused by another shop and changed the oil for us because they noticed it needed it. Car sounds great!

Huds Auto went above and beyond helping us with my stepson's truck. From the moment we bought the truck, they were professional, honest, and kept us informed throughout the entire process. They did a phenomenal job, and you can tell they truly care about their customers and the quality of their work. It's hard to find an auto shop you can genuinely trust, but Huds Auto has definitely earned ours. We highly recommend them to anyone looking for reliable, knowledgeable, and friendly service. Thank you for taking such great care of us!
