If your furnace appears to be leaking, check out the list below to help you assess the issue. Please make sure that you call a trained Erie professional to diagnose and solve the problem.
Furnace humidifier leak
A faulty internal humidifier is one of the most common causes of a leaky furnace. The furnace humidifier is connected to your plumbing system to add moisture to the air during the winter months. If your humidifier cracks or clogs, water will be leaking from your plumbing to your furnace.
This would be an unlikely problem if you have your furnace checked annually. But if you have neglected tune up, it is possible that you have an issue with your humidifier. This can potentially damage other parts of your furnace, so make sure that you have the issue diagnosed and remedied as soon as possible.
Clogged internal drain
Some furnaces share an internal drain with the air conditioner. If your air conditioner and furnace share a drain, an internal drain system could be the culprit. This could force water into the furnace; thus, causing water to leak from the furnace.
High efficiency furnaces pump cool exhaust away from the furnace. With this type of furnace, condensation is a normal process. The condensation is usually channeled into a floor drain. If the floor drain is clogged or there is a break or a clog in the drain line, water may start pooling under your furnace.
Secondary heat exchanger
If you have ruled out all the issues stated above, it is likely that you have a faulty secondary heat exchanger. This can be a costly problem that needs immediate action. If left unaddressed, you may need to replace your current unit with a newer one.
