If you have a high-efficiency furnace, condensation is most likely the cause of the leak. Condensation is a byproduct of high-efficiency furnaces. This water usually flows through a PVC pipe into the furnace room’s floor drain.
However, water can leak out of the furnace if pipes break, clog, or the floor drain clogs. Remember that condensation occurs only in high-efficiency furnaces. Because standard-efficiency furnaces use metal exhaust pipes, no condensation occurs. In this case, it is recommended to get your furnace serviced by our specialist for furnace repair in Pearson.
