Went for a maintenance call today for heat for two systems. Tested for static pressure system is passing when in heat for both. All electrical components are passing for manufacture specifications for both systems.Did a combustion test is within range. Inspected heat exchanger no cracks/leaks were detected for both systems. Temp split and is passing for specifications on both furnaces. Cleaned flame sensor and pressure switch hose for both units. Both systems are up and running before departure. Thank you for choosing LBA services-Johann
