What is a Furnace?

With a furnace, air is drawn into and out of the system. That's why it's often called a warm air system. After the air is heated, a blower pushes it through ducts. The warm air is released through vents or registers throughout your house.

The basic components of a furnace system are:

• A Burner, through which gas (natural or propane) or oil is delivered and burned.
• A Heat Exchanger, where the heat produced from the burning gas is transferred to the air distribution system.
• Ductwork, to transfer the heated air throughout the home.
• A Flue or Vent Pipe, to exhaust byproducts of combustion (such as water vapor and carbon dioxide) to the outside.

A furnace's heating ability is gauged with an Annual Fuel Utilization Efficiency (AFUE) percentage. A higher AFUE percentage indicates a more efficient furnace. A gas furnace uses natural gas, although some models can be converted to utilize propane. An oil furnace uses heating oil. An electricity source is required to run the control systems, blower, and some accessories.
