What is a furnace?
A furnace's main job is to provide a building or structure with heat. They can be fired by gas, oil, or even wood. They heat air, which is circulated through a heating system and distributed within the building by a blower.
Direct Energy, a Houston-based service company, has a great description of how a furnace and air conditioner work together. It gives a complete picture of your systems and their main components. Check it out here.
