Ductless HVAC Systems in Los Angeles – What is a Central Furnace?

Nearly every home and building has heating needs, and the most common heating method in modern times has been a central furnace. A central furnace usually heats air or water by burning a fossil fuel inside an enclosed metal casing. The heat is then distributed through ductwork by forced air, or through pipes in the case of water. The most common fuel for central furnaces in the United States is natural gas, though coal, wood, and heating oil are also common furnace fuels.

This fact offers the advantage of only having to add fuel at one central location, in heating systems that require refueling.
