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 Sundance Auto Service & Machine, 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
Always do great work with our motors in there machine shop
I ran out of gas right at the corner across the street from this shop, and the man working at Sundance was so kind, he located a gas can, filled it, asked me to please return it on my way back from getting gas, all without any question, in 110° heat, he saved me from having to walk and risk getting towed from where my truck was still in the street. A company run by empathic humans is the best in any business. These guys rock!
"WAS" a happy customer with Peoria Ford's service dept. I've used Peoria Ford for years and always took my 2011 Ford Fusion to them for all service needs. Well... my last service was terrible. (See Google Review) After a disaster with Peoria Ford's repair shop, I took my 2011 Ford Fusion SEL to this recommended Auto Repair Shop "Sundance Auto Service & Machine Shop". The shop may not look as snazzy as Peoria Ford's, but the mechanics know their stuff. John quickly and correctly diagnosed the problem within a few hours and gave me a great price to do all the work. Apparently the "Vehicle Control Arms" needed replacement as the bushings were totally worn out. A dangerous situation if not repaired. Something the Peoria Ford service department should have noticed and informed me of. But no. Not one peep about control arms from Peoria Ford. After I gave John the go ahead, Sundance not only repaired the car perfectly, but it also only took them one day to do everything. Dropped the car off that morning and picked it up the next day before noon. And I believe the price would have been nowhere near what Peoria Ford would have charged and probably still not fix the problem. Thank you, John, at Sundance Auto Service & Machine Shop for the great repair job.
Excellent
