What Is A Furnace?

A furnace is a heating system that is commonly used to warm up indoor spaces. It operates by burning fuel, such as natural gas, oil, or propane, to generate heat. The heat is then distributed throughout the building using ducts or pipes. Furnaces can be found in residential homes, commercial buildings, and industrial facilities, and are crucial for providing warmth and comfort during colder months. Regular maintenance and servicing of furnaces are necessary to ensure their efficient operation and to prevent breakdowns or safety issues.

How Does A Furnace Work?

A furnace operates by heating air and distributing it throughout a building. The following are the steps involved in the functioning of a furnace:

  1. The thermostat detects a drop in temperature and signals the furnace to turn on.
  2. The burners ignite the fuel, such as gas or oil, creating heat.
  3. A heat exchanger transfers the heat from the burners to the air passing through it.
  4. The blower fan pushes the heated air into the ductwork.
  5. The heated air is then distributed to different rooms through vents or registers.
  6. The combustion gases produced during the heating process are vented outside through a flue or chimney.

Having an understanding of how a furnace works is essential for proper maintenance and troubleshooting.

What Are The Signs That A Furnace Needs Servicing?

As a homeowner, it is important to know when your furnace needs servicing in order to prevent any major issues or breakdowns. In this section, we will discuss the telltale signs that indicate your furnace may need attention from a professional.
