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 Sunstate Auto Repair LLC, 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.

Henry is the most honest and hardworking mechanic that I've ever met...After the first visit, I knew I had found my mechanic...He goes above and beyond to run tests to ensure that he fixes your car the right way the first time. He even went to bat for me with the parts manufacturer to have a faulty part covered under a warranty that had expired. I probably couldn't tell you how much time and money he has saved me. He was even nice enough to call my dad to explain the repairs as I'm not well-versed in car mechanics. Henry comes with my highest recommendation if you're looking for a skilled, friendly, and honest mechanic in the Orlando area.
This may not sound like a big deal but they did exactly what they said they would do. Gave me an estimate. It was accurate. Gave me a time they would contact me regarding the work being complete. They had it done right when they said they would. The job they were to do was done exactly as specified. No surprises. Just honest work.
