A furnace is designed to keep you warm and comfortable. If you see water leaking out of this appliance, you have every right to be concerned. Here are some of the most common causes of a leaking furnace.

Condensation Tubes

One of the most common reasons homeowners notice water around their furnace is condensation. These appliances direct moisture and water to a drain in the floor. However, the water directed out of the furnace contains minerals that, after drying out, leave behind a hard residue that can result in buildups and clogs. 

When the tubes that push the condensation down to the drain become clogged, a leak can occur because the water has nowhere else to go, causing it to spill out. An HVAC contractor may need to clean the condensate pump of mineral accumulation or replace it altogether.

Flue Pipe

This can eventually tamper with how it fits to your furnace. If the pipe becomes loose, the exhaust gases will cool down and produce moisture, leading to leaks forming around the base of your furnace. An HVAC contractor can typically fix this issue by replacing the flue pipe with one that fits better.

Humidifier

If your heating system has a built-in humidifier, it could be to blame for a leak. For instance, to prevent dry air in your home during the winter, the humidifier needs to heat up water and disperse it to keep your indoor air moist.

However, since unfiltered water contains minerals, such as calcium, the moisture in the humidifier will leave behind residue over time, which will lead to clogs in the system. This will eventually push the water outside of the furnace and result in leaking around the base of your appliance. This issue can typically be caught during an annual HVAC inspection, in which the contractor will dislodge the buildup.
