Do you use a gas-powered furnace in your home? Well, then there is one safety risk that is essential you know. This isn’t to say that that gas furnaces are inherently dangerous—they’re not! But there is a component within it that can be dangerous if you ignore it for too long, and that’s its heat exchanger.
Like most powerful appliances or any type of equipment that creates combustion gases, a furnace can potentially create health hazards if it’s not regularly maintained, or repaired as soon as symptoms of a malfunction appear.
Cracked heat exchangers aren’t a problem that typically afflicts new furnaces—old gas-powered heaters are more prone to such a problem. When we say old, we mean about 10-15 years—this is the average lifespan for a well-maintained furnace.
