I completed a ductwork repair for a customer who was experiencing reduced airflow in their home. After inspecting the duct system, I found several leaks and gaps in the duct joints, which were causing significant air loss. I sealed the leaks using mastic sealant and reinforced the connections with aluminum tape for added durability. I also wrapped sections of the ductwork with R-8 insulation to improve energy efficiency and reduce future air loss. After the repairs, I performed a pressure test to confirm that the system was now sealed. The home’s airflow is restored, and the HVAC system is running more efficiently.
