Furnace Leak in Philadelphia, PA

A leaky furnace can wreck your day. In a perfect world, your furnace would last forever. Modern heating systems are sturdy and strong but not indestructible. Eventually, something will go wrong, and a leaky furnace is a sign that you must take action. There are several reasons why your furnace may start leaking. Luckily, Peters Associates has been repairing and replacing furnaces of all kinds since 1945, and we’re available to assist you. The following covers some of the top reasons that your furnace is leaking.


Condensation is the most common reason for a leaky furnace. Today’s high-efficiency furnaces operate with a cool exhaust and, therefore, produce condensation when operating normally. In most cases, the condensation will drain into your floor drain via plastic tubing. Sometimes, though, clogs or breaks in the line can lead to a leak. If you suspect a problem with your furnace drainage, reach out to Peters Associates.

Clogged Furnace Filter

A clogged filter is an often overlooked issue. The furnace filter traps dirt, dust, and other contaminants and can become clogged with debris. When this happens, the coils can freeze, resulting in puddles of water appearing around the bottom of the furnace. Checking your filters regularly and replacing them as needed is the best way to prevent this issue.

Humidifier Leak

Homes that utilize a humidifier connected to the heating system can have leaking caused by the humidifier. While the humidifier is pumping moisture into the system to keep your house more comfortable, it can also leak. Depending on the configuration of the system, the leak can get into the furnace and appear as a puddle of water.
