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 Familia Automotive, 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 say
Came across this shop online, thanks to Mayor Lincoln. My first time getting my service from this shop. And I have never experienced when an owner educates you about your vehicle depending on what your there for. But Clint was very professional, knowledgeable about his shop and takes really good care of his customers. And not only he fixes cars but also does all the paper work inside the office. Waiting Room is clean and hospitable. Plenty of space to sit, drink and use the restroom. Yes, well cleaned restroom. Staff was customer friendly. One guy went around to test my car and came back quick. It was not easy for me to trust anyone but they reassured you as always. Very accommodating and flexible with your schedule as long as you notify them. I would definitely return back and recommend this to other friends and family I know.
