Winters don’t get too cold here in Mesa, AZ, but the desert nights are plenty chilly and chances are your heater has been seeing a lot of activity in the last few months. Generating heat is the furnace’s purpose. But believe it or not, it is possible for a furnace to get too hot. Or rather, it’s possible for a furnace to be unable to distribute the heat it generates effectively, which can spell big trouble for your system. Here’s how.
Poor Air Flow is the Culprit
Overheated furnaces are usually caused by one of two basic issues. Either there’s something blocking the flow of air out of the furnace, or the force pushing the air isn’t sufficiently powerful. In the former case, you’re usually looking at a blockage in the ducts: a dent, build-up somewhere, or perhaps a filter that hasn’t been cleaned in a while. In the latter case, it’s usually a problem with the fan motor, or perhaps the fan itself is misaligned or broken.
Why That’s a Problem
Regardless of the cause, the issue is that the heated air simply remains in your furnace instead of moving through the ducts like it should. Not only does it force your heater to work harder to do its job—raising your monthly bills and the chances of a serious breakdown in the process—but the increased heat means greater stress to the individual components. In extreme cases, vital elements like the heat exchanger can suffer damage, and while some models will shut down the system rather than risk damage of that nature, that still leaves you without a functioning heater until a trained technician can get in and correct the problem.
