How do I know if my furnace is going to explode?

The average homeowner probably doesn’t think about their furnace very often, until there’s a problem. And like many things in life, when there’s a problem, it’s usually a big one. So how do you know if your furnace is going to explode?

The first thing you should do is understand how a furnace works. A furnace heats your home by blowing hot air through a series of metal tubes.

If you think your furnace is going to explode, the best thing to do is call a professional. Furnaces are dangerous appliances, and it’s best to leave the repairs to the experts.
