A furnace is an essential component of residential HVAC systems responsible for generating heat. It typically works by combusting fuel (natural gas, propane, or oil) or using electricity to warm air that is then circulated throughout your home via ductwork.

Types of Furnaces

Furnaces come in various types, including:

  • Gas Furnaces: Utilize natural gas for heating.
  • Electric Furnaces: Use electric coils to produce heat.
  • Oil Furnaces: Rely on oil combustion.
