Performed diagnostic inspection on furnace system after reports of temperature inconsistency and airflow issues in multiple rooms. Conducted visual inspection of ductwork using camera equipment, confirming no blockages present. Tested all damper motors and discovered air leakage occurring even when dampers were closed. Identified significant heat loss from multiple sliding doors (8 upstairs, 4 downstairs) contributing to temperature regulation problems. Closed unused vents to improve airflow distribution and recommended installation of zone panel system for better temperature control, particularly for basement-only operation as requested by homeowner.
