Work Performed: No cooling call. Upon arrival, found the Lennox air conditioner not running. Inspected the system and discovered the Nest thermostat was incorrectly wired for a heat pump configuration, which was preventing cooling. Rewired the thermostat to properly operate the AC system. Results: System is now running. The Lennox condenser (installed around 2019–2021) was very clogged with debris and is overdue for a proper coil cleaning. Informed the client that full AC maintenance is needed, but they declined at this time. Home is currently under renovation, and ductwork could not be properly inspected. Advised client to have the ducts professionally cleaned to verify overall airflow. While the AC is mechanically operating and electrical components are functioning correctly, we cannot confirm refrigerant charge or airflow performance without completing maintenance.
