For this job I performed a combo maintenance on a 7 month old Lennox split system 1. All electrical and mechanical components are clean and within manufacturer specifications. 2. Replaced return filter with one provided by Cool Air. Second filter was replaced today by customer. 3. Adjusted and secured flue pipe for proper pitch. 4. After inspecting the ductwork to determine necessary repairs, found that it needs to be properly sealed at the unit and 2 supply ducts need to be replaced. Informed customer and she opted to do those repairs at a later date. Requested to speak with a comfort advisor about replacing attic insulation and possibly looking into further replacements to the duct system. Scheduled appointment for System is operational in both cooling and heating upon departure. Thank you for choosing Cool Air Solutions
