Seasonal readiness checklist

Fresh filter inHeavy runtime season starts now — write the date on the frame. Can't see light through the old one? It was overdue.Registers & returns clearRugs, furniture, and curtains off every supply and return. Closed registers don't save money — they raise static pressure.Heat mode test-firedRun the heat for 10 minutes on a mild day — first fire smells briefly dusty (normal). No heat today beats no heat in the first cold snap's queue.CO & smoke detector batteriesCombustion heating season = carbon monoxide detector season. Test buttons, fresh batteries, replace units past their printed date.Outdoor unit clear of leavesHeat pumps run all winter: keep 2 feet clear around the unit and never stack anything on top. (Furnace-only homes: skip.)Exterior vents unblockedHigh-efficiency furnace intake/exhaust pipes (white PVC on the side wall) clear of nests, leaves, and later — snow.Furnace condensate path drainingCondensing furnaces drain water year-round. A visible drip at the floor drain is good; pooling at the cabinet is a call.

The layer that needs instruments

The checks above are yours; these are the fall items a technician measures — the failures that announce themselves to a meter months before they strand you.

Combustion analysis + heat-exchanger inspection (the crack check)
Ignition chain service: flame sensor cleaning, safety-control verification
Gas pressure, venting integrity, CO screening at the equipment
Heat pumps: defrost operation + backup-heat staging verification
