Vehicle Cooling and Heating Systems

Your vehicle cooling and heating systems are some of the most important parts of your car. Without them, our driving experience will be miserable and it will not be comfortable and safe to drive. The warm air we get from the heater keeps us warm during winter and the cool air refreshes us during the summer time.

The heating system in your vehicle is essentially a variant of your cooling system radiator. Hot engine coolant is circulated through a radiator, in many cases called a heater core. A fan is situated in front of the heater core to blow cool outside air. As this air goes over the heater core, it warms up and turns into the hot air which comes out of your heater vents.

The air conditioning system in your vehicle is composed of a compressor, condenser, expansion valve and evaporator. The refrigerant in your A/C unit is compressed in the compressor and turns it into a warm gas. In the condenser, the warm gas is cooled to a liquid state and travels to the expansion valve. As the refrigerant goes through the expansion valve it returns to a low-pressure gas and quickly cools down in the evaporator. There is a fan that blows over the evaporator and cools the air that eventually comes out of your A/C unit vents.

It is important to have your heating and cooling systems checked and serviced. Sometimes leaks may occur and mould and bacteria may grow. When this happens, unpleasant smell may come from your A/C unit as well as poor air conditioning performance.  It is essential to make sure that your heating and cooling systems are at maximum efficiency. Having a well conditioned heating and cooling systems allows the driver and their passengers to have a comfortable and safe driving environment.
