Heating & Air Conditioning

When it comes to the summer heat nothing beats a good running AC system in your vehicle. Regular maintenance and air conditioning inspections are necessary to keep it performing well. On colder winter days, you'll need a dependable heating system to get that frost off the windows and heat the cab up to a comfortable temperature. Though these two systems perform opposite goals, they run and perform from the same heating/cooling system in your vehicle.

When your vehicle's heating and cooling system is not functioning properly, it could also mean your engine may be running hot. The entire cooling system is dependant on certain parts working properly and in unison.

>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:

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

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.
