A furnace system uses a fuel source, such as natural gas, propane, or oil, to produce heat. The heat is then distributed throughout the home using a system of ducts and vents.
In a furnace, fuel is burned in a combustion chamber to produce heat. The heat is then transferred to a heat exchanger, which is a device that transfers heat from one substance to another. The heat exchanger is typically made of metal and is located inside the furnace.
Air from the home is drawn into the furnace through a return air duct. The air passes over the heat exchanger, where it is heated. The heated air is then blown back into the home through a system of supply ducts and registers. A furnace also has a control system that regulates the operation of the furnace. The control system includes a thermostat. The control system also includes a blower motor, which powers the furnace's fan, and a fuel valve, which controls the flow of fuel to the furnace.
