The East Coast was hit with freezing temperatures and blizzard conditions late last week, and we’re all still assessing the damage. When it comes to your furnace, any damage should be carefully assessed and immediately repaired. It can be tempting to try to “power through” any damage — winter isn’t going to get any gentler anytime soon — but that’s usually a big mistake. And in the case of a cracked heat exchanger, an immediate heater replacement session may be in order. To do otherwise risks more than a chilly home.
What is a heat exchanger and why is damage to it so devastating? We’ve prepared a quick summary below.
Winter is almost here, and cold temperatures are going to be staying a good long while. Your forced-air furnace was likely called into action some time ago, and by now you’re likely running it on a daily basis. Hopefully, it’s in good working order and you won’t need to worry about a breakdown during the cold winter months. Trouble with most forced-air furnaces tends to advertise itself well before it forces a shutdown, however, and wise homeowners will learn to spot them before they cause an unexpected shutdown. That way, you can deal with the issue in a timely fashion.
