Furnace Dripping Water: Common Reasons

When you notice that your furnace is dripping water, you need to address it right away. Otherwise, you might be dealing with costly problems later. The leaks need to be tackled on the onset. But do you know the reasons why a furnace drips water? Put the blame on these culprits.

Faulty Heat Exchanger

One reason why a furnace drips water is a malfunctioning heat exchanger. If you don’t have any DIY knowledge to fix the problem, the best thing to do is to bring in a professional HVAC repairman. If the secondary heart changer malfunctions, then it’s an indication that you need to install a new unit.

Condensation Leaks

Newer furnaces are generally more efficient than their traditional counterparts. A modern new-efficiency heating unit pumps cool exhaust away from the unit, thus increasing the condensation amassing on the base of the system. Chances are you have an incorrect size of flue pipe. We recommend homeowners to invest in a high-efficiency furnace to avoid this problem.

Leaky Humidifier

Water leakage can also be caused by a clogged humidifier. Furnace humidifiers are connecting to the plumbing system and need water to give off extra moisture into the air. Cracked or clogged humidifiers can cause water to leak from your plumbing system to the furnace, giving you the impression that the furnace is leaking water.

Clogged Internal Drain

Furnaces share an internal draining system with your air conditioning system. If the internal drain becomes clogged, it could redirect water into the heating system, causing it to leak water.

Leaky Pipes Near The Furnace

Leaky plumbing pipes can also cause your furnace to leak water. Also, clogged pipes can lead to a backup in the floor drain, causing the furnace to look like leaking.

If your furnace is dripping water, you can try simple DIY fixes. But if you’re unable to solve the problem, it’s time to contact the experts at Harkins Air Conditioning, Heating & Controls.
