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
