Warranty- 2020 Rheem heat pump low on Refrigerant. I preformed a electronic leak search and found leak in evaporator coil. System is still under Rheem manufacture parts warranty and customer signed up for the maintenance plan within 1yr of installing so labor warranty is extended. I will be calling supplier for availability. In the mean time 6.5lbs of refrigerant was added to get system cooling until repairs. 20x20x5, pics uploaded
