We want to reassure you upfront that natural gas furnaces are not “dangerous” appliances to have in a home. If they were general health hazards, they wouldn’t be allowed into homes in the first place. Modern manufacturers of HVAC equipment build furnaces to the highest safety standards and with multiple precautions built in. If you’ve regularly maintained your furnace and scheduled furnace repair in Pasadena, CA whenever it wasn’t working right, there is minimal chance of the furnace operating unsafely.
But any appliance that burns natural gas can potentially create health hazards because of toxic gas byproducts, and it’s important to know about what may go wrong. In this post, we’re going to look at one potential gas furnace danger and what to do about it: the cracked heat exchanger.
