Replace Your Car's AC Thermal Expansion Valve or Orifice Tube

Gears Transmission and Complete Automotive Repair

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 Gears Transmission, 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.

Testimonials

One million stars isn't enough to express my gratitude. Please read this and share it with everyone. Hebrews 13:2 "Do not neglect to show hospitality to strangers, for thereby some have entertained angels unawares." I'm no angel, but Mr. Hicks and everyone at Gears Transmission is ready for that test. I am a Trucker and I broke down, under load, on I-75 right above Gears Transmissions. What I needed to get moving again was a "T" hose connector and coolant. I went, first, to a neighboring Truck repair shop. They didn't have the part and I asked if I could pay someone to give me a ride to the nearest hardware store or auto parts store. The man said it would be awhile and cost $150. Same as a road call, plus 2 hours min. Labor. Something in my gut said to walk. Well, I walked next door to Gears and asked if they would sell me a T fitting. The guys and gals all went out of their way to help me, offering me water, or soda while I waited. They too didn't have a suitable sized "T", but the owner said we can call the parts store and have it brought here. So, with full intent to pay a normal up-charge for his time and work, I asked them to include a pair of plyers and 4 gallons of coolant to the order. When the items arrived, Mr. Hicks, not only, handed me 3 hose clamps for my project, he also asked one of his guys to give me a ride back to my truck. I pulled out my credit card, happily ready to pay just about ANY halfway reasonable amount of $$ for the amazing care and attention I had just received, BUT.... Mr. Hick refused to accept ANY, I mean ZERO, money for all of his. I made my delivery on time, Thanks to these amazing people. If they treat a Stranger in need like this, I can only imagine how they treat their customers. Sometimes, like this, it's perhaps a stranger knocking on the doors of an angel's house. Thank you Mr. Hicks, and thank you, Steve, for the ride back to my truck. I will pay it forward!
