Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Car Care USA
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 Car Care USA, 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 heard and read many greats reviews on this business so I decided to give it a try and was definitely not disappointed! I took my daughters' car in to get serviced and from beginning to end, they were very professional and courteous. As a female, I always get the feeling of condescension when I take my car in but at Car Care USA, they took the time to explain and made me feel reassured that I took my business there. Their service was very reasonable and affordably priced and our car runs great! I will highly recommend them to friends and family! Thanks!!
