D&D performed duct sealing using the AEROSEAL system which reduced the duct leaking in my 42 year system by 86% equating to almost a 400 cfm reduction in overall leakage. Amazing system, which I knew about it long before now.
The three technicians were very professional, performed their respective tasks, cleaned up and left the areas as they were found.
Thank you D&D
