here is the problem:
we run the ac on day 1. on day 2 we don't need it because of mild temp, however, around midday water starts to steam through the vents. so much comes out that it starts to drip and there is about a 2 feet collection of moisture on the ceiling.

the units are carrier and were installed 6 years ago. it is a flat roof house with ducting on the outside.

HELP

i have had several companies come out and no one knows what the problem is. i am in a real bind because the only way to dry the water is to run the unit. it is a bad repeating cycle.

THANKS FOR ANY ADVICE.
