Completed a one system fall maintenance. Blower is running at 1.8A at 100% speed. All 20KW heat strips working properly at this time. System had fault due to home having loss of power. Found systems evaporator coil heavily rusted (see attached photos) and blower wheel needs to be cleaned as well. System is running properly at this time. Customer doesn’t want to do anything about blower wheel or evaporator coil at this time.
