A heat exchanger is a device in an HVAC system that transfers thermal energy from one medium to another. A heat exchanger helps with the heating and cooling of your home. As heat exchanger is used in both air conditioner and a furnace, you need the heat exchanger to work efficiently to operate your HVAC system without any hindrance. But a heat exchanger can crack, and there can be a number of reasons behind it.

Why does a Heat Exchanger Crack?

Generally, heat exchanger cracks because of its age, but there are other reasons. One of them is bad furnace management. In an average winter, a furnace is turned on and turned off about more than 3000 times. From this, we can estimate the usage of heat furnace in winter, and if the heating furnace is not taken care of well, there’s a high possibility that the heat exchanger of the furnace will crack. You’ll need to clean and check your heat furnace’s health regularly in order to have a functioning heat exchanger in your furnace HVAC system.

A crack in the heat exchanger will prevent the heat furnace from working. As a result, you’ll suffer in the extreme winter of Dallas. Also, when your heat exchanger is cracked, your furnace will produce toxic gases like Carbon Monoxide and Nitrous Oxide, which can have adverse effects on your health.
