A Note on Cracked Heat Exchangers

A cracked heat exchanger is one of the most serious furnace issues we encounter. It allows combustion gases — including carbon monoxide — to mix with the air circulating through your home. If a technician tells you your heat exchanger is cracked, don't run the system until it's been inspected by a second opinion you trust. We will always show you the problem directly and explain your options clearly.
