What is a Furnace?

Furnaces in HVAC Systems

In Heating, Ventilation, and Air Conditioning (HVAC) systems, furnaces are the primary heat generation component responsible for warming buildings during winter months or cooling them during summer. By burning fuels such as natural gas, propane, or oil, furnaces produce radiant heat that is distributed throughout the building to maintain a comfortable indoor temperature. Furnaces play a crucial role in maintaining a stable and consistent indoor climate, regulating humidity levels, and preventing moisture buildup that can lead to mold growth and other issues. Additionally, furnaces are often used as a backup heat source during power outages or when the primary heating system is not operational, ensuring that buildings remain habitable until the main supply of heat becomes available again.
