Preformed 2 system heat maintenance on Trane heat pump 2021, and 2016 Luxaire straight electric heat. I tested all electrical components on the inside units. All tested within manufacturer specifications. The upstairs unit could benefit from having the blower wheel and evaporator coil cleaned as I did find that there were a good amount of debris/dust on them. The downstairs unit was good. The filters had been changed by the client before arrival. I inspected the units outside. Both units were in working condition. Units were heating upon departure.
