humidty

davejitsu | Posted in Energy, Heating & Insulation on January 12, 2009 04:27am

I have a customer home with soffit vents blocked by plywood Has a ridge vent and 2 Gable vents one one side. After A/C unit installed humidity level increased When he turns fan on level decreases. He spoke toa/c people they claim unit is fine. Attic has insulation. So if I open vents on soffit will that help?

    consensus is that gable end vents don't play well with any other vents, so yes, I would suggest closing the gable vents, opening the soffit up and leaving the ridge in place.

    Could you repost this with punctuation and syntax that makes it legible and understandable?

    You need to tell the whole story if you want a reliable answer.

    And why did you post this question twice? Having two simultaneous threads doesn't make for good conversations.

    Where was the AC unit installed? In the attic? If so, were the ducts sealed and insulated?

    What cause the initial humidity to rise? Just the installation or turning it on? What fan are you refering to that decreased the humidity? The AC fan? A whole house attic fan?

    Where did the humidity rise? In the conditioned space or in the attic?
