Why Is My Furnace Leaking Water?

As the weather is getting colder, the last thing you want is to have issues with your furnace. So when you see water leaking from it, you may be a little unnerved. This usually signifies that something is either leaking, dripping or not draining properly. Even though you should never see water around your furnace unit, sometimes the issue can be very minor and easily fixed.

Condensation

If you have a high-efficiency furnace, the most common cause for water around your unit is condensation. The most common cause of condensation is usually clogged condensation tubing or drains break in the condensation line and possible issues with the condensation pump if you have one.  It should be noted that a standard-efficiency furnace shouldn’t have condensation, but if it does then the flue pipe was sized incorrectly. The hot exhaust will cool down and condense within the pipe which causes it to drain back to the furnace and leak out.

Humidifier

If you notice a small device that is attached to your furnace that has various hookups for water, electricity and drainage–then you have a humidifier. Humidifiers help add moisture to the warm air that blows into your home making it easier to breathe. Issues with the humidifier, such as a clogged filter or drain can cause the unit to leak. If not fixed in time, the leak could cause internal damage to your furnace unit.

Secondary Heat Exchanger

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