How is the furnace evaluated in a fall home inspection?

In a fall inspection we run the furnace through a full operational check, evaluating ignition, heat output, distribution, venting, and visible condition, exactly when the system is about to face its hardest months. Fall is an ideal season for this: temperatures are cool enough to run heating equipment under realistic conditions, and any findings can be addressed before the first hard cold snap. We operate the furnace or boiler with its normal controls, verify it ignites and heats properly, check temperature rise and airflow at registers, and inspect the accessible components: heat exchanger areas for visible cracking or corrosion, burners and flame character, blower operation, filter condition, venting and combustion air, and, on high-efficiency units, condensate handling. We note the unit's approximate age against typical lifespan so you can budget realistically; an original furnace in a 1990s home is a line item waiting to happen. thermal imaging, available as an add-on, helps confirm heat is actually reaching every room and reveals duct and distribution weaknesses. For boilers, we evaluate the burner, circulators, expansion tank, and radiators or in-floor loops. Because a Minnesota furnace is genuinely life-safety equipment in January, anything questionable gets flagged for a licensed HVAC contractor's evaluation before winter.
