By the time the first hard freeze hits the northwest suburbs, you want your furnace ready — not failing. A little maintenance each fall prevents the most common breakdowns and keeps your energy bills in check. Here's your checklist.
What you can do yourself
- Replace the air filter. A fresh filter is the single easiest way to protect your system and improve airflow.
- Test your thermostat. Switch to heat and confirm it kicks on. Consider a programmable or smart thermostat to save on bills.
- Clear the vents and returns. Make sure furniture and rugs aren't blocking airflow.
- Check the area around your furnace. Keep it clear of boxes, laundry, and clutter for safety.
- Test your smoke and carbon monoxide detectors. Replace batteries — this is critical with gas heating.
- Listen and smell. Run the furnace early in the season. Strange noises or odors are worth a professional look before winter.

What a professional tune-up should include
A yearly professional tune-up goes deeper than DIY. A technician will:
- Inspect the heat exchanger for cracks (a safety and carbon-monoxide concern)
- Clean and test the burners, ignitor, and flame sensor
- Check electrical connections and the blower motor
- Verify safe gas pressure and proper venting
- Test overall system performance and efficiency
Why it's worth it
Most no-heat emergencies are preventable. Annual maintenance reduces breakdowns, lowers energy costs, extends your furnace's life, and keeps manufacturer warranties valid. It pays for itself.
