Gas Furnaces Most home comfort systems have two parts: an
outdoor air conditioner or heat pump, and an indoor unit, a
furnace. Furnaces heat and circulate warm air in the winter. They
also take cool air from the outdoor unit and circulate it through
your home in summer. The indoor and outdoor units are designed
to work together. When the furnace is properly matched with a
heat pump or air conditioner, you enjoy maximum efficiency and
extended system life. Furnace heating ability is measured with an
Annual Fuel Utilization Efficiency (AFUE) percentage. A higher
AFUE percentage indicates a more efficient furnace.
The basic components of a furnace system are:
A Burner, where gas (natural or propane) or oil is delivered and burned A
Heat Exchanger, where the heat 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) outside

AFUE% - Annual Fuel Utilization Efficiency. A measure of a furnace's
heating efficiency. The higher the AFUE%, the more efficient the product.
The government's established minimum AFUE rating for furnaces is 78%.
