Homeowners don't know if their furnace will fail before winter, risking expensive emergency repairs

Homeowners face uncertainty about furnace reliability as winter approaches, lacking clear guidance on whether their system needs maintenance or replacement. Without proper pre-season assessment, they risk catastrophic failures during cold months when repair costs spike 3-5x and technician availability disappears. Current solutions (generic checklists, reactive repair calls) fail because they don't provide definitive readiness answers or preventive confidence.
