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 Hardy Vehicle Designs, 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.

⭐⭐⭐⭐⭐ 10/10 — Highly Recommend! I can’t recommend Hardy Vehicle Designs enough. After being rear-ended, I initially took my car to the repair shop recommended by the insurance company, but my vehicle still wasn’t repaired correctly. When I brought it to Hardy Vehicle Designs, they were able to identify the issues right away and explain exactly what had been missed. I was also dealing with a difficult insurance claim, and they went above and beyond to help communicate with the insurance company and explain why the original repairs were incomplete. Tyler was absolutely amazing to work with. He was knowledgeable, communicative, and took the time to explain everything in a way that was easy to understand. The entire team was professional, honest, and genuinely cared about making sure my car was repaired the right way. If I ever need any automotive work in the future, Hardy Vehicle Designs will be my first call. I’ll also be recommending them to anyone looking for a trustworthy, knowledgeable shop. Thank you for making such a stressful situation so much easier!
