Analyze thermal images and visual data from [BUILDING_TYPE] to assess the efficiency of its HVAC system. Identify areas of heat loss, duct leakage, or insulation gaps in [SPECIFIC_COMPONENTS] such as vents, pipes, or walls. Provide a detailed report with annotated images highlighting inefficiencies and recommend cost-effective solutions like [UPGRADE_OPTIONS] (e.g., sealing ducts, adding insulation). Focus on improving energy efficiency while adhering to [LOCAL_BUILDING_CODES].
