Arrived on site, heavy rain present at time of service. He began inspection at the air handler. Tested stage one and stage two heat. Both stages were operating normally and putting out correspondingly warm air. Extensively tested 20kw heat strips and found them all to be working well. Tested float switch and drain line and found them to be working as intended. Measured blower motor amps, no concerns at this time. Found some bacterial growth around the blower housing and door insulation. Brought is finding to the attention of the homeowner and provided estimate to his email. Unable to proceed further at this time, informed customer I will need to come back later this afternoon once the rain has let up to finish testing on the outdoor unit.
