Q: I have a question concerning a central air conditioner in my home. The supply air is run thru ductwork in the attic. These ducts are insulated but condensation builds up internally and drips back into the house through the supply vents in the ceiling. How can I correct this problem before it causes any more damage to the ceiling, floors, furniture, etc.? Do I need more insulation around the ductwork in the attic?

A: This sounds more like a ventilation problem. When it is much warmer inside the home than outside, the heat naturally rises up, condenses in the warm ductwork, and drips back down into the living space. So insulating the ductwork would only compound the problem. Rather, you need adequate ventilation in the attic area so the warm air can circulate and escape. This could include gable vents or even dormers to keep the air moving. Proper attic ventilation will also help keep the attic dry to help prevent dryrot, mold, mildew and prolong the life of your roof. You will need to contact a general contractor to do this for you.
