Why Is My Furnace Leaking Water?

When the cold weather hits, your furnace becomes a necessity. A warm home keeps your family comfortable and cozy. However, sometimes your furnace can malfunction at the most inconvenient moments. A common issue with furnaces is seeing water around the unit. Usually, this reveals that something is either leaking, dripping or not draining properly. With different furnace units, there are different issues. Even though it’s common issue, you should never see water around your furnace unit–regardless of the type you have. Although sometimes the issue can be very minor and easily fixed, there are times where it’s a serious problem.

Condensation

Condensation is usually the most common cause of water around a high-efficiency furnace. What’s the cause of condensation? It’s usually clogged condensation tubing or drains breaks in the condensation line and possible issues with the condensation pump if you have one.  Secondly, if you have a standard-efficiency furnace, which has a metal exhaust pipe, condensation should not be an issue. However, if condensation appears, it is usually because the flue pipe was sized incorrectly. This could cause the hot exhaust to cool down, thus condensing in the pipe, draining into the furnace and then leaking out.

Humidifier

With some units, there is a small device attached to a furnace which has various hookups for water, electricity, and drainage called the humidifier. A couple common issues with the humidifier include a clogged filter or drain which will cause the unit to leak. If this is left untreated, the leak could cause internal damage to your furnace unit– which can become costly to fix.

Secondary Heat Exchanger

A secondary heat exchanger’s purpose is to remove heat from the exhaust of the furnace.  If the secondary heat exchanger is faulty, this could be very costly to fix. Also if the problem is not solved then it may be time to replace your old furnace and install a new one.
