Went for airflow issue in the basement. Did notice dampers were not closing. When one thermostat was off. Did check volts was getting power. But wiring for it was incorrect. Will come out Monday to have dampers set correctly. Did install smart ac for customer. As well did maintenance for system. All electrical components are passing for system. Refrigerant levels are passing. System is up and running before leaving. Thank you for choosing LBA services-Johann
