Some homeowners are cautious about using gas furnaces because of possible safety hazards. Burning natural gas in any appliance has some risk of uncontrolled combustion and toxic gas leaks. But as long as a furnace receives regular maintenance each year and prompt repairs when needed, the risk is minimal.
We want to focus on one specific furnace repair problem that can create serious health hazards: a cracked heat exchanger. The more you know about it, the easier it will be to prevent it.
