Found a puddle around your furnace and wondering why is my furnace leaking water? How serious is it? It looks like a minor issue but an indication of several underlying issues like structural damage, faucets’ mechanical malfunctioning, etc. You can ignore it, but you have to be ready to face the consequences in the future, like reduced efficiency, costly repairs, health risks due to mold growth, and more.
This article will take you through the common reasons behind furnace leakage, how to troubleshoot them, how to identify them earlier, and some maintenance tips. Read this article thoroughly and address any issues before they arise in the future.
Water is leaking from the furnace? There might be several reasons behind it, and understanding them is the first step to fixing the issue and preventing further damage.
Condensate drain furnace dripping water? A high-efficiency furnace produces condensation while heating, and this water must be drained properly through a dedicated condensate line. If this is blocked due to any reason, it starts backing up the water, creating leaks.
Common indications are high humidity inside and water spots around the furnace. Before fixing it, check the condensate blockages or sometimes the pump-clogged parts.
Did you notice the built-in humidification in the furnaces? They are necessary to maintain the humidity in the air indoors. It malfunctioned due to clogged parts, improper settings, and solenoid valve issues. Its indication is leakage signs around the furnace, even though it is not running.
Recall that a condensate pump is necessary to eliminate the water from the furnace. If the pump breaks down or is not working properly, it doesn’t expel water. Puddles forming and the pump not running are common signs.
Water leaking from furnace occurs when the heat exchanger breaks due to corrosion, metal fatigue, or moisture buildup during combustion over time. Water pooling around the furnace or decreased heating efficiency are common indications.
Blocked drain lines disconnect from the heater, leading to leaks. It's a common indication of water leakage when the furnace is ON.
Flue pipe vents work as an exhaust pipe so that the gas can escape from the furnace. Damage or improper installation can lead to problems such as leaks. If you feel the water around the exhaust pipe, it means there is a problem with it.
It’s also used to exhaust the combustion gasses, but when it fails, it doesn’t vent properly. Finally, water starts to accumulate inside the furnace, causing the furnace to struggle while turning ON. It also creates gurgling, dripping, or similar strange noises.
There are several other factors that contribute to this issue, such as a clogged filter, issues with the secondary heat exchanger, and a malfunctioning blower motor.
Knowing the reasons is necessary to deal with it properly. With a little knowledge, you can fix the minor furnace leakage issue if not so complex; otherwise, hiring a professional furnace fixer like Lifera® will be an intelligent decision.
First, turn off the furnace so that water doesn’t interact with the electricity.
Tip: Use an insulator or towel if the water is pooled around the furance to protect yourself from electric shock.
Inspect the condensate drain line and remove the clogged debris. Also check the line connections.
Now inspect the condensate pump. Check the float switch, clean blockages, and replace the pump if the problem persists.
Now it’s time to inspect the humidifier. Check the settings and water supply lines, and clean the humidifier pad properly.
Securely reconnect the flue pipe if it has disconnected.
Now check the heat exchanger to see whether it’s working and installed properly.
If still the issue persists, call a professional furnace repair service like Lifera®.
Recall that it’s a minor issue, but ignoring it can lead to serious issues with the home structure, plumbing system, or your health.
Over time, the water exposure causes rust on the metal parts of the furnace, leading to further problems. It can create important areas like heat exchangers.
It can cause a serious electrical hazard because of the water interaction, leading to short circuits, electrical fires, and component failure.
Standing water creates mold, leading to a foul smell that’s not good for your health.
When the furnace is not working properly, it will show reduced efficiency and higher energy bills.
A single furnace issue can lead to complete furnace system failure by damaging the electrical components, blocking drainage, corroding parts, and more.
Preventive measures can avoid furnace leakage, saving your money and disrupting your routine. Here are some tips to reduce the chances of furnace failure.
Always schedule regular or annual maintenance with Lifera® because of their extensive local experience.
Dirt and debris clog the air filter; replace it regularly.
Clean the pump and condensate line at least once a season.
Always inspect the humidifier after a few weeks to detect leaks earlier.
Ensure proper exhaust pipe installation and venting.
Keep an eye on the usage and furnace settings, and don’t put extra stress on it.
Water under furnace? It means the condensate lines have been blocked, the humidifier has an issue, or the pump is not working properly. When any of these systems are clogged, the furnace starts leaking and the water accumulates from the bottom.
It may also be caused by the damaged heat exchanger, disconnected vent pipes, or rust buildup. Take care of these things too to prevent further issues.
Sometimes furnaces leak water while the heat is running, and it happens due to condensation issues (high-efficiency furnaces). As a result of the combustion, a blockage prevents the removal of water from the condensate pipe.
The possible reasons include humidifier leaks, faulty heat exchangers, clogged filters, and airflow problems.
A leaky furnace always has some deep roots and can compromise your home heating system. From clogged drains to faulty humidifiers, regular maintenance is the key to lowering the chances of furnace leaks. In addition, if you continue to notice any leakage signs, attempt to resolve them using our methods or reach out to a professional furnace repair service such as Lifera®. Always notice the strange noise, decreased heating, or small water signs on the furnace components to be comfortable all the time.
