Climate Control and Air-Conditioning
With the enactment of federal regulations regarding the use and disposal of refrigerants, it has become extremely important that climate control services for automobiles are handled by educated and certified mechanics. Automotive Experts follows the federal standards and maintains the environment by:

Inspecting performance of the system
Checking for leaks
Recovering contained refrigerants
Recycling refrigerants
Restoring the system to peak performance
Pressure-testing the system

Your car's engine is the power source for both heating and air conditioning systems. The systems also share other components, as the following diagram shows. Here's what happens when you flip on the heat or the air conditioner:

Heating System
Heat is a byproduct of the engine's combustion process. The heat is absorbed by the coolant in your car's radiator. The coolant is then circulated through the heater core before returning to the radiator. The heating system also includes a series of air ducts, a blower motor and fan, and temperature and duct controls, which selct the desired temperature and direct the flow of warm air.

Air Conditioning System
This system shares air ducts, controls and a blower with the heater, but has its own refrigerant system. The air conditioning system is comprised of the following components:

		Compressor This is a pump that pressurizes and circulates the refrigerant through the system.

		Condensor As the refrigerant flows through the condensor, it gives up heat and converts from gas to liquid.

		Receiver/Dryer or Accumulator This is where clean, dry refrigerant is stored as it circulates through the system.

		Orifice Tube or Expansion Valve This is a metering device that controls the flow of refrigerant through the system.

		Evaporator Core Refrigerant enters the evaporator core as a liquid. Heat from the air converts the liquid refrigerant back into a gas, which cools the air before it enters you car.
