Are you one of the over 64 million homeowners in the U.S. who use natural gas for winter heat? It is that popular—but that also means that there are more people that may be dealing with safety issues. We don’t mean to say that gas furnaces post an inherent risk to homeowners—they don’t. They wouldn’t be installed in so many homes if so. In fact, current standards for gas-heating manufacturers put a special emphasis on maintaining safe operation.
But, if your furnace isn’t well cared for, you could certainly run into problems. No gas-appliance can be 100% problem-proof if it’s not adequately maintained. There’s one gas furnace danger, in particular, you should be aware of in an ill-maintained system, and that’s a cracked heat exchanger.
