The expected lifespan of commercial water heater or furnace is around 15-20 years. Furnace replacement experts remove old furnace and alter it with the new the one that will last for longer. One should check if heating bills are going unmanageable, the replacement is the best possible solution. The fact is new furnaces are efficient than the more aged ones, thus the better solution would be to replace the current furnace with the new a person rather than upgrading it time to time.
