Performed AC maintenance on a 2020 Lennox condenser. Customer reports light use of the system so far. Customer had just changed filter recently. Outdoor unit had vines growing on the panels. These were disposed of and customer was notified of the issues the air restriction can cause. Outdoor unit was washed. Service panel and compressor bay were cleaned. Refrigerant charge was verified ok. Outdoor electrical components are healthy. Indoor unit electrical amp draws are good at this time. Supply plenum had insulation that had fallen off. This was fixed today. Both unit are not protected. System is operational.
