Performed scheduled furnace tune-up and comprehensive inspection on 10-year-old unit. Diagnostic testing with Testo 310 II analyzer revealed combustion parameters within acceptable range, but identified critical issues including failing inducer motor and ignitor. Inspection of heat exchanger showed significant damage with visible leakage points, indicating imminent safety hazard. Recommended complete furnace replacement as repair is not viable; existing issues will ultimately compromise AC system function as well.
