It would be really great if when something was wrong, our furnaces could tell us what it was and then self-repair, right? While technology might make the former a possibility eventually, the latter will just never happen.
And the fact of the matter is, over the years and thanks to wear and tear, your furnace will have repair needs. It’s important that you scheduling routine maintenance every year to help reduce the risk of these repair needs growing into breakdowns or safety hazards. But even with maintenance, repair needs can crop up and surprise you—so it’s a good idea to know the signs.
