Water leaks can be destructive if not fixed on time. The source of the damage does not matter, but you need to stay alert and act as soon as you notice the first drop. One of the appliances famous for leaks is a furnace, and there are various causes. But before you solve the problem, it is always advisable to turn it off when a leak occurs. Then, clean the pooled water to prevent more damage before calling for furnace repair services. Now take a look at the reasons your furnace is leaking.

The Humidifier Might Be Leaking

Your furnace comes with a humidifier attached to it for improved air quality. If any humidifier parts get damaged or clogged, you will experience a leak. Therefore, you should first suspect and inspect this part for possible damages. The humidifier-related leaks can occur due to a lack of maintenance. Luckily this is something you can repair within minutes. Ensure that you address the minor issues on time to prevent worse complications from developing in the furnace.

A Condensation Leak Is Taking Place

The other reason your furnace is leaking is due to a condensation leak. Most furnaces today require more than one heat exchanger to work efficiently. In the process, condensation happens that later escapes through some pipes and into a floor drain. When the piping breaks or a clog occurs, a leak follows. The best thing to do is to contact furnace repair services right away.

The Furnace Filter May Be Clogged

A leaking furnace might also be due to a clogged filter. As filters clean the air in your home, debris gets trapped in between this part, eventually leading to restricted airflow. With time, the furnace coil where the air restriction happens begins to freeze, creating a leak. While the issue is repairable, you should have the filters examined periodically and replaced when necessary.

Check the Heat Exchanger

As the name suggests, heat distribution in your furnace happens through the heat exchanger. As this happens, condensation also takes place. However, there are cases where water leaks instead of condensation. Though a rare occurrence, it is possible, so a furnace repair expert also checks this part if you have ruled out all other issues. If that is the case, you will need a new heat exchanger.

Apart from pools of water near your appliance, a leaking furnace is also recognizable through unusual smells, stains on the floor, and the presence of mold. Whenever you spot any of these signs, it is best to call for furnace repair services right away.
