If you have ever had to deal with a leaky furnace in the past, you know that repairing it is a complicated, frustrating, and time-consuming process. In this article, we’ll talk more about what you should do if you find that your furnace is leaking water. Keep reading to learn more!

The first thing that you will need to do if you find that your furnace is leaking is to shut it off to stop the leak. Double check the thermostat to make sure that the entire system is off before you do anything else. Once you’ve checked the thermostat, the next thing to do is to check the gas line connected to the furnace and the electrical breakers that control the power input to the furnace. This is done to ensure that there are no more gas or electrical leaks that could pose an even more significant threat. Once you’ve made sure that both the gas and the electric circuits are shut off, you can mop and dry the floor before fixing the furnace.

Why is My Furnace Leaking Water in the First Place?
There are two types of furnaces: high-efficiency furnaces and conventional furnaces. The internal workings of these two systems are different, meaning that there could be distinct reasons as to how a leak could occur in each system. We will detail the potential reasons for each system to have a leak down below:


// There’s a Leak or a Clog in the Condensation Lines
One of the most common reasons why there is a leak in a high-efficiency furnace is that one of the condensation lines are clogged. When there’s a clog in these pipes, the moisture will have nowhere to go, causing the pressure in the pipe to build up to a point where a leak occurs.

// Your Condensate Pump Isn’t Working
If your condensate pump isn’t working properly, the water that it’s supposed to pump through the condensate line may spill out to the side, causing a puddle to form underneath the furnace.


// The Metal Vent Pipe is Creating Condensation
The exhaust vents in a conventional furnace push out the hot gas produced by the combustion process. If the venting pipe is old, it could cause the gas to be trapped within the pipe. When the system cools down, the trapped gas will condense itself and drip from the vents onto the floor.


// The Humidifier is Leaking
The humidifier helps to re-moisturize the air in the room, making it easier to breathe during the cold and dry months. If the humidifier is not working properly, the water inside the pipe can leak out, forming a puddle under the furnace. To avoid this issue, you must make sure that you have the system checked out by a professional HVAC specialist for a tune-up.

// The Leaks in the AC Pipes
Another potential issue where the leak could come from may not be the furnace, but the AC system itself. If the air vent that connects to the surface has too much moisture, the heat from the furnace could condense it. Over time, this water could drip from the vent onto the furnace.

A Quick Solution: Replace Your Furnace Filter
One of the quickest and easiest solutions to a leaking furnace issue is replacing the filter. Although it may not solve every problem, there are many situations where replacing the filter solves the problem. Experts suggest that you should consider changing the filters every 90 days to ensure that the furnace is in the best condition possible.
