Central Cooling – How it works…

The most common central cooling system is a split system, it includes an outdoor unit such as an air conditioner or heat pump containing a condenser coil, compressor and an indoor evaporator coil, which is usually installed at the same time as your furnace or air handler. The compressor pumps a chemical called refrigerant through the system.

Warm air inside your home blows across the indoor evaporator coil, the heat energy transfers to the refrigerant inside the coil. That transfer  “cools” the air. The refrigerant is then pumped back to the compressor where the cycle begins again. The heat which was absorbed by the refrigerant is moved outside your home while cooled air is blown back inside. The moisture that contributes to humidity is also condensed out of the air.

Your cooling system is combined with your central heating system because they share the same ductwork for distributing conditioned air throughout your home.

Central Heating – How it works…

Central heating systems have a  furnace. Yours may be located in the basement, garage or attic. All furnaces consist of four main components: 1) burners that deliver and burn fuel  2) heat exchangers  3) a blower   4) a flue that acts as an exhaust for combustion gas by-products.

Combustion gases are generated by the burners in your furnace and passed over a heat exchanger. Air from your home blows across the heat exchanger to be warmed. It is then blown through a system of ducts to distribute around your home.

During warm seasons your heating system works with your central air conditioning. Air is cooled as it’s blown over your air conditioning unit’s cooling coil, which is often attached to the exhaust of the furnace, and then sent over the same air ducts throughout your home.
