It’s important for us in the heating and air conditioning business to reassure customers that their furnaces are not super dangerous. Gas furnaces would never be permitted in homes—let alone millions of homes across the country—if their operation commonly posed a threat to people.
But it’s important for us to let customers know there are ways a furnace, especially an older one or one that hasn’t gotten regular maintenance, can pose hazards. Keeping up with maintenance can lower the chance of problems like this occurring down to almost nothing, but a bit of knowledge also goes a long way.
In that spirit, we’re going to look at a major furnace problem that can put your household in jeopardy: a cracked heat exchanger.
