Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Lakepoint Auto Service
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 Lakepoint Auto Service, 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.

They do only the work that is necessary. They are very honest and they get you in and out fast. I love these guys.
Great place, I highly recommend. While this is the new go-to place for my family and I, we quickly built trust in Lake point auto. Our previous mechanic retired so we were looking for a new down to earth garage. My mother had work done here so I tried lake point when a local garage Chain said I needed a new oil pan (~$500). I brought it in to have a second opinion; Rob tightened the oil pan plug with his fingers! The other shop really looked 'hard'...lake point has earned my trust. They could have told me "yeah, you need to have this done fork over your money" but they didn't. I highly recommend.
We have used Lakepoint for all of our service needs for the past 2 years now. Rob & his team service every vehicle that we purchase before we list them for sale. We are very happy with the job that Lakepoint does and we will continue to have our vehicles serviced here.
