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 Beach Auto Care, 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.
We are visiting from Illinois and the check engine light came on in our vehicle. I stopped in and spoke to Josh, explained that my code reader indicated a faulty O2 sensor. Josh explained what could cause this code and suggested a diagnostic be done before simply changing parts. Diagnostic was done, sensor changed and we are back on the road. Great staff from Josh, to the office staff, to the technicians. Highly recommend.

l decided to have Beach Auto Care rebuild my transmission after talking with Josh, the manager. You will feel confident I'm sure, in having Beach Auto Care do your auto repairs. The office staff is friendly & knowledgeable and their mechanics are top notch and provide quality service. l will not hesitate to bring my car back to Beach Auto Care for any future repairs, and will recommend Beach Auto Care to all my friends and family.

The service was awesome. Dealing with the service manager and office folks was a real pleasure. They gave me a perfect diagnosis, and repaired my truck at a reasonable price. I've used them several times and have nothing but good things to say.
