What Is Furnace Puff Back and How Can I Fix It?
December 27, 2018
Puff backs are explosions that occur when oil-burning furnaces don’t ignite properly due to system oil leaks, clogs or other problems. If a furnace connects to a forced-air system, the soot and smoke from a puff back is distributed through the duct system to every room it serves. It contaminates the air and leaves a grimy, sticky residue on virtually every exposed surface. A puff back creates an overwhelming mess, and if it’s not cleaned promptly and properly, it can cause permanent damage to a home’s contents and serious health problems for those who live there.
