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 Anderson Garage, 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 have been going to Anderson's Garage for more than 20 years. They always go above and beyond. They are knowledgeable and honest which is something I truly value. I recommend them highly.
We have been trusting our vehicles with Anderson Garage for over 30 years, and they have never disappointed us. Sean and team have maintained the high degree of integrity and quality that we first encountered with David Anderson (same location) back in the 1980s.

Carlos R. did a great job in caring for my car and was very professional. It is obvious he cares about his customers and is very knowledgeable. This was my first time at Anderson and his work earned my trust and earned Anderson Garage
my business for future vehicle work.
If you don't understand what your car is trying to tell you, bring it to theses folks. They talk "car".
