Came out for no heat call on Upstairs heating system and to verify operations for main floor and basement systems. Home has 3 2024 Goodman Heat Pumps. UPSTAIRS: Found upstairs system has a bad Nest tstat that does not give power to "O" wire for reversing valve. Verified wires good. Also found outdoor disconnect wired improperly and blown fuse for plug-in. Cause of blown fuse still unclear, will need to reconfigure wiring properly then replace fuse to fully test upstairs outdoor unit. Also system was found with no filter, installed 20x24x1. System does not have TE Standard flood protection however they do have emergency pan and float switch. Made customer aware of benefits of wet switch and strongly recommended. MAIN FLOOR: System operating properly at this time. Disconnect box also wired improperly however no blown fuses so system getting 240v and running. Also no UV Protection, wet switch or filter. Installed 20x25x1 filter. Does have condensate pump and emergency pan with float swi
