Went for a maintenance call today for heat. Tested for static pressure system is passing when in heat. 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. Cleaned flame sensor and pressure switch hose. Did notice water panel for humidifier needs to be replaced. Customer approved and did replace the water panel.System is up and running before departure. Thank you for choosing LBA services-Johann
