Our Certified Home Comfort Specialist discovered what looked like a flex duct that was not connected to the main air supply. If left in this manner, the unconnected flex duct could cause adverse side effects in the attic. The mixing of cold and hot air would create moisture and over time microbial growth would occur. These homeowners were smart enough to call Dr. Energy Saver Delmarva when something didn't quite feel right to them and are so happy they did!
