There is a drain pan under the evaporator coil. Most likely the drain line
is plugged. Clean it out and pour a little bleach in there to get rid of
any mold spores. Not too much as you don't want bleach fumes circulating
around the house either.
As others have mentioned the drain for runoff condensate is the first
thing to check.
It may also be worth verifying your coil isn't freezing up while yer
at it. That can cause melt in in places the drain isn't exactly
expecting. Failing to change air filters can lead to airflow
constriction and suddenly you form a sheet of ice on your coil that
eventually melts somewhere. Refrigerant level issues can also lead
There are all kinds of devices that will alert you that there is a problem
with overflow of water.
Ask your HVAC service technician and he will be able to fill you in.
The devices are after you find the reason of why you are getting water on
If your drain pan discharges to the outside of the house you can do a
quick fix with a wet/dry vac.
Just find the drain, put the vac hose over the outlet & press hard
enough to get a seal and vac till it runs freely.
That is so true but if the condensate pans is dirty and the homeowner can
not clean the pan the problem will come back again soon.
A couple of years ago a condensate pan pad that contained some sort of
insecticide that really did the job of killing the algae and all for the
whole summer. The only problem was you could not use when it was found that
the homeless were filling a container to drink form. They would fill the
container with the cold condensate water and would get sick.
The water is most likely condesate. That's water that has condensed on
the cooling coil. The coil is supposed to condense moisture out of the
air when the system is running, but it isn't supposed to drip it onto
the floor, instead the water is supposed to run into a drip tray and
then outside through a condensate pipe (drain line).
There are several possible causes for water to drip from the unit
instead of running out through the condensate line. My best idea is
for you to call an hvac company out to correct the problem.
