Gas furnaces are a powerful and energy-efficient way to heat a home. We’re familiar with the the usefulness of a gas furnace in Tofino, BC for a household, and we never want to discourage people from looking into installing a natural gas furnace.
But any gas-burning appliance comes with some level of safety risk. Not a large risk, because otherwise these appliances would never receive approval for home use.

In that vein, today we’ll examine one of the ways a natural gas furnace can become hazardous: a cracked heat exchanger.
