If you have noticed that your furnace is leaking water, here is a list of the most common issues:There is a clogged drain. Condensation from air conditioning coils contains bacteria that can form slime and clog the drain.
There is a condensation leak. High-efficiency furnaces create condensation as they utilize cool exhaust and then blows it away from your unit. When the tubing is damaged, broken or not functioning correctly, this could be the cause of your leak.
Standard efficiency furnaces should not have condensation. A leak is particularly unusual and could indicate an improperly sized flue pipe. If this is the problem, then hot exhaust might be condensing in the pipe as it cools down.
To see if your furnace is high- or low-efficiency you can examine the vent pipe. If the pipe is PVC (white plastic), then it’s a high-efficiency unit. If the pipe is metal it is a standard-efficiency furnace.
The secondary heat exchanger is not functioning properly. The leak might be caused by the secondary heat exchanger. This repair can be expensive, so most customers decide to replace the furnace as opposed to repairing the exchanger.
There is a humidifier leak. A humidifier that isn't working properly can cause water issues. If you’ve stayed on top of your annual HVAC maintenance, then this probably isn’t the issue because your service technician most likely would have noticed the problem. If you haven't had a furnace check in a while, schedule an appointment immediately. This type of leak could cause serious damage to your unit.
Internal drain system clog. A plug in the internal drain system that operates in both the air conditioning unit and the furnace, could be directing water into the furnace.
Don’t ignore leaking water issues. Leaks can cause significant damage to your equipment, walls and flooring, and can also lead to harmful mold growth.
