The condensation drain line is plugged.
Attic condensation around ac.
Look for air escaping from anywhere besides the grates.
You may need more duct or attic insulation in order to solve the problem.
Whenever there is a contact between the hot humid air and cold metal surface then there will be sweating or condensation on the metal surface so it is very important to have a proper insulation for the air handler ducts in case the portion of the duct is coming in contact with the unconditioned air outside.
If air is able to escape around the ac vents rather than flow through the grates as it should it can cause condensation to build up and drip from the ac vents.
The colder the air is inside the duct the greater the chance of ductwork sweating.
The threshold for condensation to occur is that the temperature of the cold surface has to be below the dew point of the water vapor in the nearby air.
If your air handler s in the attic leakage through the ceiling may occur.
Occasionally the secondary condensation pan will also clog and not drain.
Air handling units in attics should have a secondary condensation pan in case the primary condensation pan overflows.
Is there water or moisture around your ac vents.
There are two main ways to solve this problem.
The simple physics behind sweating is.
You can install insulation on the attic side of the register boot and you can make sure that your duct is adequately.
Excessive condensation from air conditioning is a sign you have an ac issue.
It is normal for condensation to be around the drain pipe this is a common sign of the ac unit being hard at work even more so on hot and humid days.
Improper or no insulation of ducts.
More so if the unit is in the attic.
For more information on this.
Puddling of water around the drip pan is usually noted.
The easiest thing you can do to fix water leaking from your ac vent is to reach up and feel for any air escaping from around the sides of the air vent.
You can convert your vented unconditioned attic into an unvented conditioned attic.
This colder surface then chills the surrounding air to a temperature below it s dew point which causes the water vapor to condense into a liquid just like on the outside of a glass of iced teas sitting outside on a hot day.
Condensation forms when warm humid air comes into contact with a colder surface like your air conditioner s ductwork.
Water builds up in the ceiling and eventually there will be a drip if the homeowner is lucky.
As the humidity level rises outdoors condensation will gradually begin to form on the surface of your air conditioning ducts.
What causes condensation to form on the air ducts and then leak into your ceiling.
It s a natural process and similar to the way a chilled soda begins to sweat once you take it out of the refrigerator on a hot day.
Have drain pan shutoff switch installed and equip it with a float.
Drip pan overflows happen when the plastic tube that conveys.
