Performed single system heating maintenance. The system is from 2021, communicating, and has 2 zones. I evaluated the electrical, filter, drains, cleanliness, refrigerant, and safeties. The system is heating to manufacture specifications. I noticed some growth within the system, a 35mfd capacitor reading 29mfd, and that there is a 1” gap above the filter. Recommendations 1. Upgrade the filtration of the system to an Aprilaire filter. This filter will keep the system cleaner and fully seal and be free of gaps. Estimated life span of the filter is 6 months to a year. Also, the first filter is included. 2. Growth is forming in blower compartment. This is completely normal with a heat pump system. It is advised to install a u/v stick to combat the growth formations. 3. The capacitor for the outdoor unit is reading weak. This part has to fully fail for it to be covered by warranties. I will provide pricing to replace before failure.
