This morning, I performed comprehensive air duct sealing at a residence in Apex, North Carolina. The home's HVAC ductwork had significant air leaks, resulting in reduced system efficiency and uneven cooling. Using a specialized duct sealing spray, I carefully coated all accessible joints, seams, and connections in the supply and return ducts. I also sealed any visible holes or gaps. This process has significantly improved the system's airtightness, allowing for proper airflow and enhanced energy savings for the homeowners.
