Water is leaking from my Air Conditioner (AC) coil

Every year we receive calls from frantic homeowners stating that there is water leaking from the air conditioner coil on top of the furnace. Since your home’s central air conditioner does not use water to cool the home, where does this water come from? And why is it leaking?

Where does the water on my AC coil come from?

Water leaking from air conditioner coilSplit-system AC units produce condensation moisture on the indoor evaporator coil while removing humidity from inside the home. This moisture runs down the coil and into a drain pan located below the coil, where it is then diverted out to a drain (normally a floor drain, or into a condensate pump if no floor drain is available).

If water is leaking out from the edges of the coil, and onto and down the side of the furnace and onto the floor, chances are you have a plugged drain opening that is causing the drain pan to overflow. It’s also possible that your drain pan is cracked, or in the cases of older coils, rusted through. But well over 95% of these situations are merely caused by a plugged condensate drain, which is easily corrected.

If you see water leaking out from your indoor AC coil, it is very important to have this repaired immediately. Not only can the leaking water cause damage to the home’s floor, carpet, etc, but water leaking into the furnace can result in damaged components and expensive repairs. Turn off your AC unit immediately if you notice a leak from the coil, and contact us to have the problem corrected.

Do you have water around your furnace or AC coil?

In most cases, this is just an easily-corrected minor problem. But if left alone, it can result in expensive repairs.
