The Michigan Winter HVAC Checklist: 5 Things to Do Before the Snow Flies

Michigan winters don’t wait and neither should your furnace maintenance. Avoid unexpected breakdowns, high energy bills, and safety hazards with our simple 5-step checklist. From DIY fixes to professional inspections, here’s how to keep your home warm and efficient this winter.

1. The Filter Fix

A furnace filter can save hundreds on your heating bill. Check your 1-inch filters every 30–60 days for dust buildup and replace them as needed. Clean filters improve airflow, efficiency, and reduce strain on components like the blower motor and inducer motor, keeping your furnace running smoothly.

2. Thermostat Strategy (Energy Savings)

Set your smart thermostat back 7–10 degrees when sleeping or away. Always use Auto, not On, to avoid running your furnace unnecessarily. Proper temperature control helps your control board and gas valve operate efficiently, saving energy and reducing wear on the system.

3. The CO Warning (Safety First)

Test your Carbon Monoxide detectors before firing up your furnace. Dust or flue issues can create CO hazards. A professional inspection will also check flame sensors, pressure switches, and limit switches to ensure your system is safe and ready for Michigan winter.

4. The Clear Zone

Keep clutter, boxes, and debris away from your furnace and vents. Proper airflow improves efficiency, prevents short cycling, and protects critical components like the igniters, blower motor, and inducer motor from unnecessary wear.

5. Professional Tune-Up (Fast Repair & Peace of Mind)

Only a licensed technician can inspect the heat exchanger, ignition system, control board, flame sensor, and gas valve — the key steps to prevent mid-winter emergencies. Professional maintenance ensures all your furnace components are working safely and efficiently.
