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 Jim's Towing & 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.

I brought in my Toyota Yaris early this morning due to a check engine light that came on the day before. I know Mondays are very busy for your shop and Bob said it may take some time before he can start working on it. I said no problem & I understand. I got a call in the early afternoon letting me know my car was done and he fixed the Timing Solenoid (VVT) and my car was ready to be picked up! I was so happy and picked up my car shortly after. My husband & I only bring in our cars to your automotive shop as we trust you and your staff. You are honest and very close to where we live. Thank you again for all the hard work you do and for taking care of our vehicles!! :)
