How Furnaces Work

Furnace Service in Philadelphia

Furnaces are an extremely popular heating system. They can be used to heat homes both large and small, and for commercial, industrial, or residential applications. You use your furnace every day in the winter – but just how does it work? Our heating experts at Green Heating, Cooling, & Electric explain how furnaces work and how you can get the most out of your heating system.

How Furnaces Create Heat

Furnaces use a combination of air and fuel to generate heat. The furnace has an electric ignition that is used to ignite the fuel, which then starts the combustion process. As the fuel burns, it releases heat energy and causes air molecules to expand and rise. This heated air is circulated throughout your home by a fan or blower.

The combustion process also produces exhaust gases, which must be vented outside. This is done through an exhaust vent or flue pipe attached to the furnace. The furnace control system monitors the temperature and adjusts the fuel flow accordingly to maintain a constant level of warmth throughout your home.

Furnace Power Sources

Furnaces can be powered by natural gas, propane, oil, electricity, and other fuels. Natural gas is the most common source of fuel for furnaces. Propane and oil are also commonly used as they provide a steady supply of heat energy. Electric furnaces can be less efficient than gas furnaces but may be an option in homes without access to other fuel sources. For example, many communities do not have access to natural gas lines and must rely on electric heating systems. If you are not sure which type of furnace is best for your home, our heating technicians can evaluate your needs and recommend the best option for you and your family.

Furnace Maintenance and Efficiency

Furnaces require regular maintenance to ensure they are running at peak efficiency. This includes inspecting and cleaning the furnace, checking the air filters, lubricating moving parts, and testing safety features such as the smoke detector. Regular maintenance can help extend the life of your furnace, reduce repair costs, and ensure your furnace is running at maximum efficiency. We recommend scheduling a heater tune-up at least once a year before winter begins. This will help ensure that your furnace is in good condition before it gets cold.

Your furnace may be able to run more efficiently if you upgrade it with an energy-saving thermostat or other features, such as variable speed blowers or zoning systems. Ultimately, the best way to maximize your furnace’s efficiency and extend its life is through regular inspection, maintenance, and repair.
