Furnace leaking water in a Hamilton home

Why is my furnace leaking water” is a common question. Fortunately, it’s often not a serious problem and one that you can resolve quickly.

A furnace is a heating system that keeps your home warm in colder climates. These systems are great at keeping you warm but can have problems. A furnace that leaks water is one example of such a problem. You can fix this common problem by cleaning up the mess and identifying the source.

Leakages can be frustrating, and you should address them immediately.

Continue reading to find out the most common reasons your furnace is leaking water and simple ways to resolve the issue right away.

Humidifier Leak

A humidifier can be attached to the furnace in some homes. These humidifiers can add moisture to the air and provide many benefits. Water can drip to the floors if the humidifier leaks. A damaged component or clog around the humidifier can cause leaks.

Call an HVAC professional if you see water leaking from your furnace. Sometimes, repairs can take only minutes. If you do not address the problem immediately, it could become much more severe.

Condensation Leak

A condensation leak could cause a furnace to leak water. Condensation leaks are one of the most common causes of water issues. High-efficiency furnaces require two heat exchanges to function correctly. Condensation results from this process, and the moisture escapes through your home via pipes. This water drains through a floor drain.

Leakage can occur when these pipes burst or become clogged. It is essential to contact a professional immediately after you notice the problem. Don’t wait too long to get help. 

Filter blockage

Filter blockage or clogging could cause a water leak in the furnace. These filters clean the air and keep us safe, but debris can build up over time. Debris restricts airflow through your furnace coil, leading to frozen coils and leaking water.

To prevent costly repairs and minimize damage, you should inspect your furnace filter every so often and have it replaced if necessary.

Plumbing Leak

Is there a water leak coming from the furnace? Although you might think the water is coming from the furnace, it could be coming from your plumbing system. It could also mean that your furnace is working correctly, which could help you save a lot of money. This plumbing issue is not something to ignore.

It’s easy for plumbing leaks to be mistaken for furnace leaks because of their proximity to your furnace. Plumbing leaks could indicate a damaged or blocked plumbing pipe. Call a plumber or HVAC technician immediately to get the repairs done.

AC Unit Leakage

You can use an air conditioner and furnace in the same season if you live in milder climates. The condensation pan builds up over time as your AC unit runs. Some water can drip onto your furnace if the pan gets too full. It may seem like your furnace is experiencing water damage, but it could simply be a condensation pan overflowing. If this happens, empty the pan or call an HVAC professional.

Heat Exchanger Issue

A heat exchanger problem could also cause water around the furnace. In transferring heat through your system, heat exchangers create condensation. Although it is uncommon, condensation can cause water leaks. Experts recommend checking for heat exchanger leaks if there aren’t any other causes. Repairing this problem can prove costly. The problem could even require a replacement heat exchanger. A licensed professional must inspect your heat exchanger.

Is your furnace leaking water? Get on top of it!
