More than 64 million homes in the US use natural gas to heat their houses, and most of these homes use a furnace for the job. It’s no surprise that gas furnaces are the popular option for keeping cozy in the winter. They produce heat faster than electric ones, and do it quickly, efficiently, and economically.
Although gas furnaces are built to be as safe as possible, there are potential hazards. If you’re using a gas furnace to heat your home, it’s imperative to be aware of the things that could go wrong. One of these potential problems is a cracked heat exchanger. This is not a minor repair by any means. While gas furnaces do have a special feature to turn the system off if something malfunctions, a cracked furnace heat exchanger can be subtle and dangerous.
