In 2007 we installed a new attic A/C system. This was a complete system replacement. New sealed and insulated distribution and duct work, new air handler, and new condenser and piping. The previous system,30 years old, had a number of problems. One of those problems was collection of mositure in the ductwork during the winter months. We took great pains in installing the new system to insure that it would not have the same problem. :eek:Much to our supprise, on a warm day when the temperature in the attic rises above freezing, condensation in the form of water will drip from our ceiling registers. The moisture also gets into the plaster and causes damage. Is there a way to solve this problem?
