Why Is My Furnace Leaking?

Published by Steven Weiland

A leaking furnace is never a good sign. This could happen for a multitude of reasons, but no matter the cause, it’s important to get your furnace repaired as soon as possible. Leaks can cause serious damage not only to your furnace, but to the rest of your home as well. The most likely reason for a leaky furnace is a condensation leak in high-efficiency furnaces, but lets consider all possible options.

Furnace Condensation

Most high-efficiency gas furnaces produce condensation that is directed to a floor drain. If the tubing or pipes that lead to this drain are clogged or damaged, the water in them may begin to leak onto the floor. You can determine if you have a high-efficiency furnace by looking at its vent pipe – an HE furnace has a plastic, usually PVC vent pipe. A standard furnace has a metal vent pipe and should never have condensation. If it does, you may want to ask your technician if your flue pipe is the correct size.

Humidifier Issue

Your humidifier could potentially be leaking inside your furnace. However, scheduling annual maintenance for your furnace and HVAC system should help to avoid this issue.

Internal Drain Clog

In some HVAC systems, the air conditioning unit and furnace share an internal drain. If this is the case in your system and your AC is still running, a clogged internal drain could be sending the water from the AC unit into the furnace instead of down the drain.
