Arrived on site to perform cooling maintenance on 14 year old Lennox rooftop package unit. Went onto roof and disconnected power. Removed all panels. Checked all electrical connections. Checked conditions of CFM and blower. Checked evap coil and drain line and drain pan. Checked capacitor readings for CFM and compressor blower. Capacitor for compressor was very low, customer approved replacement. Reconnected power and checked amp draws for CFM and compressor and blower. Checked refrigerant levels. Checked temperature split. CFM bearing are going out. Quoted replacement price to customer but he is not interested at this time. All work is complete
