Customer stated that AC had been vibrating house wall (above foundation posts) very loudly. I cycled system in cooling several times, condenser fan blade slightly out of balance but not enough to effect operations. No signs of obstruction inside outdoor unit. Unable to recreate the issue at this time. Advised customer to contact us if the issue persists. Performed clean and check on gas furnace, cycled system in heat, conducted combustion analysis, measured temperature rise, tested and inspected all electrical components and blower motor assembly, inspected burner tubes, cleaned flame sensor, condensate trap and EAC, flushed drain, set humidifier for winter and checked water panel which does not need changed at this time. Everything is operating within specifications.
