When it comes to keeping your home warm in the dead of winter, the last thing you want to see is a pool of water collecting underneath your furnace. Although this is rarely a catastrophic issue, letting a leak go unfixed can permanently damage your furnace and may eventually lead to a total loss of function. Leaking water can be a symptom of several different problems, depending on your type of furnace and how it was installed. Identifying where the water is slipping through and fixing it quickly, however, will ensure that your furnace can be repaired at minimal inconvenience to you and your family. 

Condensation Leaks

High-efficiency furnaces hold on to combustion gases longer than traditional models, allowing them to extract as much heat energy from their fuel as possible. This also gives the gas enough time to cool down and form condensation. High-efficiency furnaces solve this problem by catching condensation and draining it out of the system through a small tube. When the line or drain becomes clogged, or if the line cracks, the water has nowhere else to go and leaks out onto the floor. A furnace repair specialist can examine the condensation system, find the source of the leak and repair it with relatively little trouble. 

Malfunctioning Humidifier

Many homes come equipped with a humidifier attached to the furnace. The humidifier prevents air from getting too dry inside the house, but when something goes wrong, it can be bad news for your furnace. Humidifiers are typically located inside the furnace and can clog or spring leaks, causing water to overflow and pour into the furnace itself. Having your furnace serviced regularly by a technician can halt this problem before it even starts. But if your furnace has not been inspected for several years, a leaking humidifier can cause extensive harm and require expensive repairs. Whenever you spot leaking water beneath a furnace with a humidifier, turn off the humidifier and call in a professional immediately to mitigate the damage as much as possible. 

Leaking Flue Pipe

Traditional heaters do not generate condensation because they dispose of hot air before it has time to cool down. These gases are funneled through a flue pipe to be vented into the atmosphere. On the way, they may cool down enough to form condensation, but the water should roll down the pipe and drip outside. If the flue pipe was not installed correctly, though, then any excess water may flow back into the furnace instead. Pipes that are too small or run uphill may be part of the problem, or you might have a leak between the flue pipe and the furnace. Schedule a service call with a trusted local furnace repair specialist to have the pipe looked at and hopefully corrected with few changes to the system.
