Furnaces can leak water. If water is pooling around your furnace, make sure that you deal with the problem as quickly as possible. A leak can cause water damage to your walls and floors, which can cost you a lot of money if it’s not dealt with immediately, but it can also cause the death of your heating system. Ignoring the problem can be very costly.
If you notice a leak, review the list below to help you assess the issue. Call us, and we’ll send one of our trained professionals to accurately diagnose the problem and solve it.
A malfunctioning internal humidifier is one of the most common causes of a leaky furnace. Your furnace’s humidifier is connected to your home’s plumbing system to add moisture to the air during the winter months. If your humidifier clogs or cracks, water will leak from your plumbing to your furnace.
A leaking humidifier would be an unlikely problem if you have your furnace checked annually, but if you have neglected it, it’s possible that you have an issue. This can also potentially damage other parts of your furnace, so be sure to call us to diagnose and solve the issue as soon as possible.
Some furnaces share an internal drain with your air conditioner. If they share a drain in your HVAC system, a clog could be forcing water into the furnace, causing water to accumulate around its base, rather than draining away.
High-efficiency furnaces pump cool exhaust gases away from the furnace. With this type of furnace, condensation is usually channeled into a floor drain. If your floor drain is clogged or there is a clog or a break in the drain line, water can start pooling under your furnace.
Secondary heat exchanger
If you’ve ruled out all the issues stated above, it’s likely that you have a malfunctioning secondary heat exchanger. This can be a costly problem that requires immediate attention. If left unaddressed, you may need to replace your current heating unit with a newer one.
