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 Borche's Hi Tec Auto Repair, 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.

There are hardly any words to describe what the phenomenal team of people Borche’s Hi Tech Auto, especially Jason. I tasked them with a nearly impossible engine replacement when my son’s 1997 Chrysler LHS had a catastrophic failure. This car was immensely sentimental to our family because it was the last project my father, as a long-time employee of Chrysler worked on before his retirement. We lost my dad in 2018 but kept his car in excellent condition so when it failed, we could not imagine letting it go. As it turns out it was most definitely a labor of love with all of the “labor†falling on Jason and his team. He is an amazing person, so unbelievably knowledgeable, driven and motivated to complete this project. I will be forever grateful. The amount of time to not only tear the engine down, and put it back together, but all the time and effort to track down other needed parts that did not come with the new engine, as well as other parts that we! re needed because it was so old. I just cannot say enough about his persistence and dedication. I would have thought he was doing this for his own family. Thank you does not seem like enough but THANK YOU for being a miracle worker.
