As the frost melts usually after you turn off your ac the condensation can drain via your ac vents.
Ceiling registers sweating.
Setup a ladder below the ceiling vent with the greatest amount of condensation.
If you ve noticed condensation on an ac vent air conditioner vents sweating or worse an ac vent leaking water you re right to be concerned and start investigating what might be going on.
The system is running on low speed so far anyway.
Since dew point temperature is the temperature at which water vapor condenses into water the result is sweating.
Loosen the two screws holding the ceiling vent in place with a phillips screwdriver while keeping one hand on the.
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.
In summer when the air conditioning is on the reverse happens.
The colder the air is inside the duct the greater the chance of ductwork sweating.
This traps heat in the attic which then warms the ceilings.
It is almost 100 outside and humid today.
My upper level systems ducts are in the attic.
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.
Sweating ceiling supply register.
Sweating happens when the warm moist room air contacts the chilled diffuser face while the supply air temperature is below the dew point temperature.
Improper ventilation and insulation of home attic space can produce high humidity levels and trap.
The most common cause of ceiling condensation is an attic with too little insulation and ventilation.
I noticed just today that one and only one of the ceiling supply registers is dripping a lot of condensation.
As the humidity level rises outdoors condensation will gradually begin to form on the surface of your air conditioning ducts.
If you let it go you could end up with property damage along with a potential air conditioner repair bill.
A dirty air filter can indirectly cause water to drip from the ac vent in the ceiling by causing the ac to freeze up.
In an attic like this wintertime ceiling condensation can form when cold air from the attic hits your warm ceiling.
