How do I know if my heater is broken?

The first way to tell whether your heater is broken is to feel the vents — if cool air is coming out, there’s a problem. However, it could be a tripped circuit, loss of power or a different problem. For example, if you hear loud or unusual noises, this could also be a sign of breakage, as most modern heaters are fairly quiet. Finally, look at your power bills. If there’s an unusual spike in prices, your heater could be working improperly and running inefficiently.
