What maintenance can a technician do when the heater is already working?
A seasonal visit can include cleaning and drainage work as well as checking the heating cycle. At this home, the work included washing the outdoor unit and flushing the condensate drain, the line that carries moisture away.
What happened on this visit
During the heating check, the technician noticed a light buildup of dust on the indoor air-distribution equipment. The other indoor heating components were working, and the outdoor electrical components checked within specification. The outdoor wash and drain flush were the maintenance performed that day.
When comparing maintenance visits, ask which cleaning tasks are included. An inspection finding, such as dust inside the system, is different from a cleaning service performed on it.
