The most common reason for a leaking furnace is condensation-related. If the leaking water is caused by condensation, there are a few possible explanations. We recommend looking first at the condensation drain or tubing for a break or a clog, and if that isn’t the problem, it could be an issue with the condensate pump. If the problem turns out to be unrelated to condensation, the leak could be coming from an internal drain system clog.
