What is a furnace?

A furnace is a heating system that is used to warm up the interior of a building or home. Furnaces typically use gas, oil, or electricity as a fuel source to produce heat, which is then distributed through a duct system to various rooms and spaces.

The furnace is composed of several components, including a heat exchanger, a blower motor, and a combustion chamber. The heat exchanger is responsible for heating the air that will be circulated throughout the home, while the blower motor moves the air through the ducts and into the various rooms. The combustion chamber is where the fuel source is burned to produce heat.

Furnaces are available in a range of sizes and efficiencies, with higher efficiency models using less energy to produce the same amount of heat. They are generally considered a reliable and effective way to heat a home or building, but require regular maintenance to ensure safe and efficient operation. A lower efficiency furnace is still a popular choice with homeowners, as it has less upfront cost. They also require regular maintenance to ensure the highest levels of safety.
