A gas furnace is a system used to heat a space, usually a home, that creates its energy from a source of gas. The pilot light ignites the gas source, which converts to heat through a process within the unit. Determine that your home or office has a gas source available to power the furnace and what size space you will need to heat before shopping these top-rated choices. Advanced models can include energy-saving powers and quieter functioning that can cost between $500 to thousands of dollars.
