Insulation the answer to air-conditioning issue Q I am getting a lot of condensation around two of the air-conditioning vents coming out of my cathedral ceiling. No other vents in the house do this. It is enough to wet the plasterboard around the vent, causing it to decay. What is wrong, and how can I fix it? The air-conditioning man said the duct is not laying flat. We caulked, but the problem continues.
