Performed heating maintenance on a Daikin heat pump system and a Bryant electric air handler Changed 20x25x4 and 16x25x4 filters with ones we provide Inspected wiring for electric heat kits No signs of overheated connections Wires all tight and secure Amp draw on heating elements was within spec Heat pump indoor and outdoor coils are clean Capacitor tested in specification for heat pump Tested defrost function to verify proper operation Only issue found is a broken drain line for the attic system. Water is collecting in the emergency drain pan, so nothing is leaking into the ceiling. This does need fixed to prevent the drain pan rusting out completely and then leaking. Sent proposal to make that repair.
