Today I arrived in Muldoon and met with the homeowners to do their fall heating evaluation of the HVAC system. I evaluated system for performance and safety, I verified all power to both indoor and outdoor units, verified performance and operations. System is completely operational and ready for heating season, today while onsite I flushed the indoor water removal system in attic, washed outdoor unit using water and treated outdoor electrical cabinet with electrical insecticide. I also replaced both air filters in home customer provided too me, they are both same size 12x30x1. Upon departure system is left following schedule in auto mode, cooling is set to 74 and currently 74 indoors.
