It turns out that this happens because the condensed water cools plus rests inside the furnace, unfortunately, most residential boilers are not high-efficiency boilers with provisions to eliminate plus eject the condensed water out of the furnace, then such highly efficient boilers used commercially have condensation pipes that eliminate any moisture that forms after use; When this condensed water is not drained, it accumulates plus can pose extreme risks to your Heating, Ventilation, plus A/C system, one of the consequences may be corrosion of parts, especially if they are prone to rust. When you realize that the furnace is leaking, the best move would be to call your Heating, Ventilation, plus A/C professional for immediate intervention. There is not much you can do since this is a professional job requiring a particular skill set to achieve! Furnace leaks need to be attended to before they get out of hand immediately.
