What is a Gas Furnace?
A gas furnace is a heating system that creates heat by burning a gas, such as liquid propane or natural gas. The fuel is ignited by the system’s burners and the heat exchanger warms the air passing over it. Once air is heated to the desired temperature, the system’s blower circulates the heat through the duct work and into the living areas. Gas furnaces are a popular heating option for Lexington home and business owners. There are many models available which offer a range of energy efficiency levels and convenience features. Lexington gas furnaces can be expected to last approximately 10 to 15 years, though regular maintenance can prevent wear and tear, extending service life beyond this range.
