Condensation Leak In fact, this is one of the most common reasons for this issue. As many furnace models today have high-efficiency ratings, they require two heat exchanges to work properly. This process causes condensation, and this moisture escapes your home via pipes. This water usually goes through a floor drain.
Why is there condensation in my furnace exhaust pipe?
The incorrect size of the exhaust pipe is often responsible for the condensation leak. As the furnace exhaust cools down within the pipe, condenses, and becomes water vapor, it leads to condensation leak. Additionally, vulnerable joints allow for condensation to build up, leading to condensation leak.
How do you stop condensation on a flue pipe?
How to Mediate Flue Condensation
- Adjust the furnace temperature: Make sure that the furnace temperature is hot enough for the gases to freely flow through the flue and out into the atmosphere.
- Improve the flue design: Have a professional HVAC tech look at your flue and recommend improvements to the flue’s design.
Is condensation around furnace normal?

Why is my furnace flue leaking water?
The Possible Causes of Your Leak
You might have a clogged condensation drain or tubing, a break in the condensation line, or issues with the condensate pump, if you have such a pump. A standard-efficiency furnace extracts some heat from the combustion gases and quickly vents them out the exhaust or flue pipe.

Can a dirty furnace filter cause condensation?
Yes, a dirty filter can lead to the issue of too much condensation on your furnace. It will restrict airflow, which can cause a leak. Also, if your cooling system is connected, the air could freeze, and then when the air conditioning unit turns off, the water can drip into your furnace, causing issues.
