On arrival system was off. Furnace ran as intended. Indoor unit clean, biological growth beginning to form in supply plenums and the uv bulb is on but out of tolerance. Recommended iaq 200 as a better long term solution that also kills anything in airflow or replacing current surface killing uv bulb. Outdoor unit passed all electrical testing but was overamping on start up. Recommended a compressor saver or a soft start kit to address this.
