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 Norris' Garage, 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.
OUR REVIEWS
Stephen Sheppard, 01/25/2025Highly recommend Norris' Garage - They provided exceptional service, thorough and expert work, and their communication is absolutely top notch. I recently had my 302 engine replaced with a Jasper engine at Norris Garage, and I couldn't be more impressed with the experience. From start to finish, their service was exceptional. The team demonstrated outstanding professionalism and expertise, ensuring everything was done right. Additionally, they provided extra care to my Bronco that I was not expecting. For example, the dash light indicators on my bronco had fallen behind the instrument panel (because it's an old truck), and the mechanics at Norris garage fished around the back of the instrument panel to find the small light indicators and glued them back into place - this is just one example of many of how they went beyond expectations to ensure that I was taken care of as a customer. Communication was top-notch throughout the entire process. They kept me informed every step of the way, answering all my questions and providing updates on the progress. Their transparency and customer service set them apart. I highly recommend Norris Garage to anyone in need of automotive services. Whether it’s a major engine replacement or routine maintenance, they go above and beyond to deliver quality work. I’ll definitely be returning for future automotive needs!
