Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Lakeview Car Centre
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 Lakeview Car Centre, 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.

I wanted to thank all the people at Lakeview Car Centre for their beautiful work. Before I turned 70, I was lucky enough to buy a NEW car. I took good care of it, as I would never get another one. Well, I got hit broadside and my car was not so pretty now. I took my car to your Lakeview car centre for help. They worked on it and got new parts...and worked...finally calling me for pick up. I went and stood there. It looked like my new car again! WOW! Thank you-thank you for all your hard work and my "Looks Like New Again" car! you are the BEST!
