Why Is My Furnace Leaking?

October 15, 2015

After a long hot summer, you will probably switch your thermostat from cool to heat to keep your home warm and comfortable. As heating season comes into full swing, your furnace will be used more and more and you may notice water dripping or laying around the base of your furnace. If your furnace is leaking, you may have nothing to panic about. Continue to read our blog below for reasons as to why your furnace may be leaking.

Top Reasons Your Furnace Is Leaking

Condensation – if you have a high-efficiency furnace, the most common leak is caused by condensation. High-efficiency furnaces use dual exchangers to extract heat from the home to save energy. Once the air is cooled as it exits the home, condensation forms and runs through the drain pipe to exit the home. If you notice condensation, it is most likely due to damaged or broken piping or a clogged drain. When condensation is unable to exit the home, you will see water at the base of your furnace. This problem is relatively inexpensive and can be repaired by an HVAC technician.

Secondary Heat Exchanger – the heat exchanger is one of the most important parts of a well-functioning furnace. After years of wear and tear, unfortunately this piece malfunctions and needs repair. Repairing the secondary heat exchanger is often a costly fix; therefore, you may want to look into replacing your furnace, especially if it is over ten years old.

Leaking Humidifier – a leaking humidifier is often avoidable with regular HVAC maintenance; however, if you do not schedule annual maintenance checks, you may have a problem with your humidifier. Improper drainage, clogged pads, or too much water pressure are just a few issues your furnace humidifier may have. Contact an HVAC professional to schedule repair service immediately to prevent internal damage to your furnace.

Clogged Drain – If your AC unit and furnace share an internal drain system, you may have a clog a time or two in your drains. Before you call your local plumber, contact an HVAC professional to make sure there are no other issues with your heating system.
