Silver AC pm, summer rain storm during pm. Asked about micro power guard filters and UVV UVC lamps and customer wants to wait for a special deal or fall to have them replaced. Asked about hot and cold spots and customer said master bedroom struggles in the mornings, I showed them how the dampered louvres work to help with airflow. Washed heat pump and checked both capacitors. Checked blower and evap coil and both could use a cleaning in place, system could also use a duct cleaning. Foam front panel on return plenum had come loose, and taped it back in place with foil tape. Checked volt drop and and amps, and tested system in cooling and heating. System operating well at this time.
