Three Furnace Sounds You Should Never Ignore.
Several households have reported hearing loud banging or booming when they turn off their furnaces. If you are also experiencing the same issue, gas accumulation may be to blame. Never disregard loud explosions or booms since they may indicate a severe problem, such as a cracked heat exchanger. Cracked heat exchangers pose a threat to carbon dioxide emissions.
You should immediately turn it off when you hear bangs or booms from the furnace and contact one of our specialists for furnace replacement in Fishers, IN. This issue may also be caused by expanding and contracting air ducts and dirty burners, but only a competent furnace specialist can establish this with certainty.
