Why Does My Furnace Leak Water?

A common household disaster is water damage. A water leak can be extremely inconvenient and even cause mold to grow. It can make you sick and can be extremely expensive to repair, and as a result you might need furnace replacement in Stony Brooks, NY, sooner than expected. 

A water leak from your furnace could result in costly repairs, damaging your property and endangering your health. In this case, you will need the expertise of a trained HVAC professional as soon as possible. 

Reasons for Water Leakage

If you, too, are facing issues with your furnace and looking for furnace service in Stony Brook, NY, then you must contact our expert. Here are a few reasons why your furnace might be leaking:

Condensation Leaks

Do you have an efficient furnace rating of 90% or higher for Annual Fuel Utilization Efficiency (AFUE)? If you own a high-efficiency furnace, your system will likely produce condensation. A condensation leak can be caused by damaged or clogged tubing or a clogged floor drain.

Remember that condensation should only happen if you neglect furnace service. If you happen to reside in Stony Brook, NY or the surrounding areas, have our technician examine the exhaust pipe to see if you have a standard-efficiency furnace because a standard furnace has a steel exhaust pipe; it should not condensate.

Blocked Air Return

A clogged air return is another common cause of furnace leaks. When your furnace is placed inside the wall, an air duct may connect the furnace to the outside of your home. If this duct becomes clogged with dust, the air that passes through it may no longer be screened by your furnace before it re-enters your home.

This could end up causing the furnace to overheat, and it could also indicate a leak. For furnace replacement in Stony Brook, NY, you should seek the expertise of our HVAC specialist.

Clogged PVC Drain Line

If your furnace is starting to leak water on the ground, the source may not be the furnace itself. It could be originating from a clogged PVC drain line. This drain line is responsible for transporting any spilled water away from your furnace.

If it becomes clogged, you may notice an increase in the water around the furnace. This could be an indication of a drain line leak. You can call our skilled expert for heat pump repair in Stony Brook, NY.

Blockage in the Vent Pipe

A blockage in the vent pipe directly led outside is another common cause of furnace leaks. It’s essential to understand how your furnace vents outside your home so you can thoroughly inspect it and ensure there aren’t any clogs before they cause a leak.

If there are no blockages, look for condensation in the vent or the return air duct, which helps connect to the outside of your home.

Evaporator Coil Issue

Your heating and cooling system cannot function without an evaporator coil, a series of pipes that sits atop your furnace.

This is how it works:

  • The blower motor in the furnace circulates residential air through the evaporator coil.
  • The coil absorbs the heat from the air, cools it, and returns it to your residence as colder air (done through your air ducts)
  • The evaporator coil also serves to dehumidify the air (turning it into water)

The moisture in the air drips into a pan just above the furnace and blower motor. The excess water drains to the floor via a drain. Water can overflow to the burners, blower fan motor, or evaporator coil if that drain becomes clogged or plugged.
