Why is my Furnace Leaking Water?

Posted on November 16th, 2015 by carrolladmin

With peak heating season right around the corner, now is the time homeowners should have their HVAC systems checked. A tune-up after a couple seasons of downtime is the best way to guarantee your equipment works efficiently and provides quality comfort this winter.

There’s a reason we emphasize seasonal maintenance

Seasonal maintenance is a comprehensive inspection of all HVAC system components.  We call it “seasonal” maintenance because it’s conducted during an specific window of time prior to peak usage months. Although furnaces are used during cooling season, it’s essential to check them for undetected problems prior to turning on the heat.

One of the most common problems is a furnace that is leaking water. There are several potential reasons this is happening. First, it’s important to know whether you have a high efficiency or standard efficiency furnace. Check out the vent pipe. If it’s a white PVC pipe the unit is high-efficiency. Standard efficiency units have metal exhaust pipes.

Common reasons for furnace leaks

Condensation: High-efficiency furnaces create condensation. Although some amount of condensation is normal, an actual leak is typically caused by either broken or malfunctioning tubing, or a clogged drain line. Standard efficiency units do not produce condensation, so any water is likely an indication of incorrectly sized pipes. Both situations require prompt action.

Humidifier leaks: Many furnaces and HVAC systems come equipped with a humidifier. These units can leak for a number of reasons, like overly high water pressure and drain line clogs. This is unlikely to happen with a well-maintained unit; however, if you’ve neglected preventative maintenance, call a professional right away.

Drain system clogs: An internal drain system operates both the air conditioning and the furnace. If air conditioning is still running, and both systems share a line, it could be routing water to the furnace. Systems with a combined drain line can also become clogged, resulting in a furnace that’s leaking water.

Oftentimes when you have a heating or cooling emergency, drain lines and water backup is the cause. Any leaking or pooling water around your furnace is an indication of a problem that requires immediate attention.
