Annual Furnace Maintenance Checklist
A yearly furnace tune-up before winter improves safety, efficiency and reliability.
Annual furnace maintenance is the cheapest way to avoid winter breakdowns and keep efficiency high. Here's what a proper tune-up includes.
What a professional tune-up covers
A technician cleans burners, checks and cleans the flame sensor, inspects the heat exchanger for cracks, tests safety controls, verifies gas pressure and combustion, and checks the blower and airflow.
What you can do between visits
Replace filters on schedule, keep vents and returns clear, test your CO and smoke alarms, and watch for new noises, smells or short-cycling.
Key takeaways
- Book a tune-up in early fall, before peak season
- Change filters every 1–3 months
- Test CO alarms monthly
- Keep the area around the furnace clear
