Went for a tune up call today for heat. When doing inspection on furnace. All electrical components are passing for manufacture specifications. Did a combustion test is within range. Inspected heat exchanger no cracks/leaks were detected. Checked temp split and is passing for specifications. Did replace both filters for customer. Cleaned flame sensor and pressure switch hose. Did check humidifier water panel is good and water is running properly. System is up and running before departure. Thank you for choosing LBA services-Johann
