Too much humidity in winter
I just got a new furnace and a/c. A/C ran fine all summer, but we just had to run the furnace for an extended period over Thanksgiving for the first time since we purchased it. The ceilings and wall are drenched. Ive tried several things, but am getting it in every room of the house. I've already checked the roof for leaks and confirmed everything (furnace, dryer, etc) are venting outside properly. I checked the humidity in the rooms for a day and it ran consistenty between 88% and 91%. It's ruining the walls and ceilings and developing mildew every few hours. I clean and dry it at least twice a day. Any ideas what can be causing this? This is quickly becoming an urgent issue.

Did the installer also install a humidifier in your system? It may be set too high. I found this link that describes a problem similar to yours. They want money for more information, but either your installer or one of the experts here may be able to tell you whether its adjustable by the homeowner or if the installer needs to come back out and do it.

I don't have a humidifier, which is what's really baffling me. I'll check the sites mentioned. thanks

Maddog - I posted a reply at contractortalk. I copied this from a local columnist written this weekend:

"Don't burn unvented gas logs more than an hour or two at a time. Gas logs produce lots of moisture, so if you see water condensing on windows, turn the logs off and crack a door or window. Never go to bed and leave them burning"

I didn't see a reply from you, Grumpy. I think he still has a problem. And I am curious.
