Discovering water pooling around your furnace can be alarming. Not only is it a sign that something is wrong, but it can also lead to water damage, mold growth, and costly repairs if ignored. While your furnace’s main job is heating air, certain systems especially high-efficiency furnaces can produce condensation. When everything is working properly, that water drains away safely. But if you notice leaks, it’s time to investigate. Monterey Peninsula Sheet Metal & Heating will share what water leaks around your furnace could mean and why you shouldn’t ignore them.
Condensation Problems
High-efficiency furnaces with an AFUE rating of 90% or higher produce condensation as part of their operation. Normally, this water is drained away through condensate lines. If those lines are:
• Clogged with dirt or debris
• Cracked or disconnected
• Improperly installed
The water can back up and leak around the furnace. A professional can clear or repair the drain line to ensure proper water flow.
Clogged Condensate Pump
Some systems use a condensate pump to move water from the furnace to a drain. If the pump fails or the reservoir becomes clogged, water may collect and overflow around your furnace. If you hear unusual noises or see water around the unit, have the pump inspected and replaced if necessary.
Humidifier Leaks
Many furnaces are paired with a whole-house humidifier. These systems connect to your home’s water supply, and if they develop leaks or clogs, water can pool around the furnace. Check the humidifier for cracks, loose connections, or mineral buildup. Repairs or part replacements may be required.
Plumbing Leaks Near the Furnace
Sometimes the furnace isn’t to blame. If water pipes run close to your furnace, leaks from plumbing can make it seem like the furnace is leaking. A professional inspection can help determine if the problem is your furnace or nearby plumbing.
Air Conditioner Condensation
If your HVAC system combines air conditioning with your furnace, the air condition’s evaporator coil could be the culprit. When the condensate drain line for the air conditioner gets clogged, water can overflow and appear near the furnace. Cleaning the air conditioner condensate drain line will fix the issue.
Heat Exchanger Problems
In rare cases, water leaks can indicate a crack in the furnace’s heat exchanger. This is a serious issue because a cracked heat exchanger can also leak dangerous carbon monoxide into your home. If you suspect this problem, turn off your furnace immediately and call an HVAC professional.
Why You Should Not Ignore Furnace Leaks
Even small amounts of water can lead to:
• Rust and corrosion of furnace components
• Electrical malfunctions
• Mold and mildew growth in your home
• Expensive repairs if left untreated
