Question DetailsAsked on 7/9/2012

Why is water coming out of my ceiling A/C vent?

I have an A/C unit in the attic above the vent in my master bedroom where water was dripping. We have had heavy wind/rain storms recently and lost electricity for several days. When power was restored and the A/C unit came back on, I noticed the water dripping and figured it was condensation from the heat in the attic, no power, etc. However, last night I was woken up at 2am by a "shower" of water coming from the ceiling and spilling all over my dresser and the floor. It stopped after a few minutes - but I've left towels on the dresser, just in case it continues. The unit in the attic sits in a pan, that has a small amount of water. There is no water on the floor of the attic, however the ductwork looks mildewed.

This can happend if the evporator coils freeze up, if you live in a humid enviorment or have not had power for a few days, one solution is to ensure the blower is always running for about 24-48 hours even if the cooler part is not turned on, this ensures that the coils drain properly, also ensure that the drip line is not clogged.

It may also happen in case you are using an old model A/C, which does't have a proper water dranage system. Call your engineer and establise a proper water dranage system. On the contrary, there could be leak in the current water dranage system. Simply call your engineer.
