Does furnace use natural gas

Yes, furnaces can use natural gas as a fuel source. Natural gas is one of the most common types of fuel used in residential and commercial furnaces. Natural gas is popular because it is relatively inexpensive, burns cleanly, and is widely available in many areas.
 
When a furnace is powered by natural gas, the gas is ignited by a pilot light or electronic ignition system. The gas then burns in a combustion chamber, which heats a metal heat exchanger. Air is blown over the heat exchanger, which warms it up and distributes it throughout the building via ductwork.
 
It’s worth noting that other fuel types can be used in furnaces, such as propane, oil, and electricity. The type of fuel you choose will depend on various factors, including availability, cost, and the efficiency of your furnace.
