Completed one system fall matience on 2 year old heat pump/air handler. System was operating properly at this time. I checked blower amperages, checked operation of the heat strips. Cleanliness of the unit itself as well as the filter and ductwork. Heat pump capacitor 40/10 raited tested at 39.44/9.89, pressures were checked and passed. Attic needs more insulation currently has about 9 inches throughout recommend 14-16 inches of insulation for optimum energy efficiency. Pictures and estimate attached.
