Every year the pattern repeats. The first genuinely cold night arrives, thousands of heating systems are asked to run hard for the first time in six months, and a predictable share of them fail. Our phones do not stop. The homeowners who prepared in the fall are not the ones calling.
Test your heat before you need it. On a mild day in early fall, turn the thermostat up and let the system run a full cycle. Listen for unusual noises, check that every room is warming, and note any burning smell that persists beyond the first few minutes — a brief dusty smell on first startup is normal, anything lasting longer is not. Finding a problem in October means scheduling a repair calmly. Finding it in January means an emergency call.
Schedule a professional tune-up before the rush. A fall heating inspection covers the things you cannot check yourself: heat exchanger integrity, combustion quality, draft, gas pressure, and every safety control. The heat exchanger inspection is the one that genuinely matters for safety — a crack allows combustion gases including carbon monoxide into your living space, and it is not detectable without proper instruments.
Replace the filter and keep replacing it. Heating season means the system runs far more hours than it does in shoulder months, and filters load up correspondingly faster. A restricted filter makes a furnace run hotter than designed, which can trip the high-limit switch and, over time, contributes to heat exchanger stress.
Address the building envelope, not just the equipment. Attic insulation and duct insulation do more for winter comfort in most older homes than any equipment upgrade. Ducts running through an unconditioned attic lose substantial heat before the air reaches a register; insulating and sealing those runs is one of the highest-return improvements available. Seal obvious air leaks around windows, doors, and rim joists while you are at it.
Test your carbon monoxide detectors and replace the batteries. If you do not have CO detectors on every level of the home, install them before heating season starts. This is non-negotiable in any home with gas or oil equipment.
Finally, bleed your radiators if you have hydronic heat. Trapped air keeps hot water from filling the radiator, which is why the top stays cool while the bottom heats. It takes a few minutes per radiator and noticeably improves output.
