Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Grand Motorsports and Service, Inc.
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 Grand Motorsports and Service, Inc., 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.

Had a bearing go out on my boat trailer, heading up to the upper peninsula. NO One else would touch it. They were the second place I called. They understood my situation and got me in. They said would fix if they could get the parts. Well guess what they got the parts and installed them. Both hub bearings on right and left side. So thankful for them going above the average for me. I would recommend these great people anytime. Thank you for saving me from my trip from hell
