Can Your Furnace Leak Water?

August 22nd, 2019 by cverdone

You have recently noticed some accumulating puddle of water sitting adjacent to your furnace. It’s quite abnormal that you’ve always associated furnaces with a drying effect rather than moisturizing effects. Little known to the majority of people, furnaces may start leaking suddenly. Regardless of the season, dripping water from your furnace could be a sign of a serious problem with the system. Contact our HVAC professional for immediate inspection and correction. So, what could be the reason behind the water leaks from your furnace?

Leaking Vent

Furnaces that use gas or oil as sources of fuel use vents to redirect toxic gases and fumes away from home. The vent system normally is installed through the wall and ceilings safe from the public’s eye. These pipes are covered with small caps to keep moisture at bay. However, over time, the caps may fall off. It creates a path for water to drip through the furnace and settles at the bottom of the HVAC system. Open vents pose a risk for shock hazards through exposing water as well as clogging the system which may create breeding grounds for insects.

Problematic Condensation Drains

Running furnaces may condense some part of the air’s moisture despite its main aim being drying out the air they heat. The condensed moisture is required to gather in a central drain that’s linked to a buried pipe. In some cases, the central duct may develop issues from clogged pipes or broken drain pipes that transport water out of the HVAC system.

Although you could attempt cleaning the condensed water from the system, without fixing the problem, the furnace will continue to leak. It is best left for an HVAC professional to fix the broken or clogged parts.

Heat Exchanger Problems

A defective heat exchanger in the system could also trigger water leakage. Modern furnaces come pre-installed with a secondary heat exchanger to ensure maximum heat exchange from the waste gases. Like any other machine, wear and tear may cause the exchanger to become clogged or cracked. Due to inadequate heat conversion, condensation begins to drip off the surface. Normally, this is the most severe problem when inspecting water leaks from a furnace system. Defective heat exchangers require the replacement of an entire furnace unit. Your technician will rule this out with a thorough inspection before proceeding with the diagnostic measures.

The complexity of a furnace system requires expert skill to determine the source of the water leaks. Also, immediate remedies to furnace water leaks ensure that you prevent mold and rot damage and continue enjoying your furnace’s services. Is your furnace experiencing a water leak?
