How does a central heating/cooling system work?

Central heating and central cooling systems are separate things but they are matched to work together.

Central Cooling
The most common central cooling system is a split system, which includes an outdoor cabinet containing a condenser coil and compressor, and an indoor evaporator coil, usually installed in conjunction with your furnace or air handler. The compressor pumps a chemical called refrigerant through the system.

How It Works
Once warm air inside your home blows across the indoor evaporator coil, its heat energy transfers to the refrigerant inside the coil. That transfer, in turn, "cools" the air. The refrigerant is pumped back to the compressor where the cycle begins again. The heat absorbed by the refrigerant is moved outside your home while cooled air is blown inside. Moisture that contributes to humidity is also condensed out of the air.

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

Central Heating
Central heating systems have a primary heating appliance, such as a furnace, typically located in your basement or garage. All furnaces consist of four main components: 1) burners that deliver and burn fuel, 2) heat exchangers, 3) a blower and 4) a flue that acts as an exhaust for gaseous by-products. Depending on your situation, region and needs, you can choose from heating systems running on either gas or oil as fuel, or a hybrid packaged system that can use both fuel types.

How It Works
Combustion gases are generated by the burners in your furnace and passed through 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, often attached to the air circulating fan of the furnace, and then sent through the same air ducts throughout your home.


Customer Service
I just wanted to thank you for your excellent technical service and unparalleled customer service. My family (we represent 3 separate households) has been utilizing your company for the last 20 years, and there is no other company we would rather do work with. Your value and abilities are second to none. We replaced a whole heating and A/C unit, plus all new ducting, a few years ago and you were extremely professional throughout the entire process. The system has been working flawlessly. We just wanted to say thank you and wish you continued success."
