Your furnace creates a lot of heat when it is on. This may seem obvious since it has a single purpose – and that’s to heat your home. But your furnace isn’t only generating heat. It also creates carbon monoxide fumes that need to be safely transferred outside of your home and away from the air you breathe.
That’s why your furnace has an exhaust flue – to move these fumes outside. Unfortunately, it’s not uncommon to have problems with your exhaust flue as the system ages and parts wear down. If your furnace exhaust system is showing signs of damage, you definitely want to address the problems early before they worsen.
