AUTOMOTIVE AIR CONDITIONING

San Jose Auto Repair provide component of automotive air conditioning  material.

 Your air conditioning system is made up of a compressor, a condenser, an evaporator, receiver drier, refrigeration lines, pressure and cycling sensors, and an electric cooling fan for the condenser.

Compressor:

This is the heart of your a/c system. The compressor is what takes the refrigerant (the gas) and pressurizes it so it will cool the air. It's run by an engine belt. The compressor also has an electrically operated clutch that turns the compressor on and off as you demand more cool air.

Average cost $359 - $589

Condenser :

Located at the front of the engine, next to the radiator. Sometimes the condenser will have its own electric cooling fan, too. The hot, compressed air passes through the condenser reduce the tempurature. As it cools, it becomes a liquid.

Average cost $150 - $350

Evaporator :

The evaporator is another little radiator usually located under the dashboard near the heater core. As the super-cool liquid is passed through its tubes, a blower forces air thru it and cools to about 45 degrees in a properly operating system as it exits the vents to the passenger compartment. As it warms up again, the refrigerant starts turning back into a gas.

Average cost depends on the location of the evaporator, if it is located in the engine compartment it will be hundreds less than if it is located under the dash. $175 -$650 evacuate and recharge of A/C system extra $99 utilizing R134 Freon.

Thermal Expansion Valve

also known as an Thermal Expansion Block Controls the flow of super-cool refrigerant to the evaporator.

Average cost $100 - $200, evacuate and recharge of A/C system extra $99 utilizing R134 Freon.

Drier or Accumulator:

The drier, also known as the receiver-drier, is sort of the safety catch for your system. The compressor is only supposed to compress the gas form of your refrigerant. However, there's always a chance that some liquid could make it back that far. The drier catches this liquid before it can damage your compressor. Since even a small leak or careless installation can introduce water moisture to the system, the drier absorbs this chemically, using what's called a desiccant. The drier also has a filter that catches contamination in the system.

Average cost $99 - $149, evacuate and recharge of A/C system extra $99 utilizing R134 Freon.

A/C hoses and O-rings:

Leaks at the a/c hoses and o-rings which seal the hoses are the most common source of freon loss.

Average cost $39 - $99 for o-rings, $89 - $179 for hose replacement, evacuate and recharge of A/C system extra $99 utilizing R134 Freon.

Tip: if your defroster does not automatically engage your air conditioning system, run the A/C system at least 20 minutes a week during the winter. This will keep the o-rings lubricated and compressor healthy when you really need it during the summer months.

HEATER SYSTEM

Main components to the heating: Coolant, Heater Core, Heater Control Valve and Thermostat.
