Did Inspection for 1 system in home that is zoned and has 13 zone dampers attached to it Customer er stated they will change Aprilaire model 413 system filter. Customer advised me that they were having air flow issues within the home. Stated that some areas weren’t getting as good as airflow. Found that 6 zone damper failed. Qty 1: for zone 3, qty 1: for zone 2, qty 4: for zone 1 that will need replacement. Customer approved to have all 6 that failed replaced. Checked over all of system, system is in good shape, outdoor condenser coils were very clogged. Recommended cleaning to help system performance, customer approved to have done as well. Everything inside cabinet is nice and clean. Outdoor capacitor and contactor tested good with no issues. Will follow up with customer Monday about part availability and get them schedule to do repairs.
