Typically the condensation from a high efficiency gas furnace is channeled to a floor drain. Poorly designed exhaust pipe. Condensation from air conditioning coils contains bacteria that can form slime and clog the condensate pan drain tube. The condensation from a high efficiency gas furnace is generally guided to a floor drain via a drain hose.

Your leak could be a result of the. High efficiency furnaces extract heat from the combustion gases for a longer period of time than a standard efficiency furnace does causing the gases to cool then condense. A problem with the heat exchanger in your furnace could cause a water leak and unfortunately is one of the most expensive repairs. The condensation is routed to a floor drain.

If you ve looked into the other possible causes of a leak and can t find it it may be the heat exchanger. There are two main issues that can cause your conventional furnace to drip water. An easy way to tell if you have a high efficiency furnace is to look at its vent pipe. Why a conventional furnace leaks water.

If there is a pvc pipe attached you have a high efficiency furnace. You can prevent slime and eliminate drain tube clogs in two easy steps. If so they commonly produce condensation. To be more specific the pipe that comes out of the unit is attached to this leaking section which is attached to a pvc elbow then another piece of pipe and so on.

When you see water puddling around the furnace with the a c running you have a clogged condensate drain tube. Your leak could be a result of the condensation tubing becoming clogged or from breaks in the line. It could also be a result of the floor drain becoming clogged. However if this tube becomes clogged or if the drain on your floor becomes it can cause water to backup and leak out of the furnace.

A new unit may need to be installed. This is typically flown out of a pvc pipe that comes from the furnace and drains into the floor drain in your furnace room.
