What is an AC hose assembly?

Air conditioning hose assemblies are used to carry refrigerant and lubricant between the components of car, truck, bus, heavy equipment and other mobile air conditioning systems. These systems typically utilize both a pressure and return line. Various end connection types are available depending on the vehicle.

How does an A / C compressor change to a liquid?

The compressor pressurizes the refrigerant then it enters the A/C condenser as a gas. The high temperature, high pressure gas is cooled as it goes through the condenser. This changes the gas to a liquid. Then the liquid goes to the evaporator through an expansion valve or metered orifice. This quickly depressurizes the liquid.

When do I need to replace the a / C accumulator?

The A/C accumulator should always be replaced after the system has been opened. The A/C accumulator is the refrigerant reservoir, and houses the desiccant which removes moisture in the refrigerant. The orifice tube should be replaced any time A/C service work is performed.

Where can I get a new AC compressor?

TechChoice carries more than 1,200 new and remanufactured AC Compressors. New AC Compressors are sourced from highest quality vendors, same as most auto parts stores. TechChoice has its own in-house compressor remanufacturing. Evaporator Cores, or Evaporator Coils, are located in the dash of a vehicle.

How does an A / C compressor work in an evaporator?

An orifice tube was installed in the evaporator inlet tube, which eliminated the need for an expansion valve. The A/C compressor is controlled by a pressure cycling switch. The A/C compressor runs until the pressure drops below 26 PSI, then cycles back on at 45 PSI. This also eliminated the POA valve.
