Noticing water under or around your furnace can start alarm bells ringing in your head. You may worry about whether you will need furnace repairs or even a new furnace. However, by understanding the possible causes of the leak, you can be prepared with some solutions.

3 Potential Causes of a Leaking Furnace

1. Clogged Drain or Tubes

The most common type of leak is caused by condensation building up. When the furnace extracts heat from the combustion gases over a long period, it causes the gas to cool. This cooling leads to condensing. Normally, the condensation should be routed to a drain somewhere on the floor. However, when the drain or any tubing gets clogged, it may lead to condensation building up and causing a leak. Calling a professional to assess the problem and see what furnace repair may be needed is the best solution for this issue.

2. Exhaust Pipe Issues

 It is also possible the exhaust pipe is the wrong size for your system. This pipe is connected to your furnace and is designed to vent away any gases produced during combustion. The gas is moved out quickly when the pipe is working correctly. However, if a pipe is the wrong size, it may take longer for the gas to leave the system, which results in it having time to cool down and condense. A professional will either need to redesign your pipe configuration or install a new one to correct this issue.

3. Leaking Humidifier

While not all furnaces have humidifiers, it is easy to tell if yours does. They are small devices attached to the outside of the furnace and have hookups for water, electricity, and drainage. A humidifier helps add moisture to the warm air that is blown into your home, which helps aid the air's breathing quality and enables you to avoid dry skin. However, if the unit's drain or filter becomes clogged, it can lead to leaks. Depending on the issue, this may require a professional to clean the unit or replace the filter.
