Use this checklist to keep your home safe, warm, and efficient before the first cold snap.
1. Change or clean your furnace filter
Dirty filters reduce airflow and raise energy use. ENERGY STAR advises checking monthly and replacing at least every three months, or sooner during heavy use.
Know your filter rating. MERV ratings compare how well a filter captures particles. Follow your system specs and choose the right balance of airflow and filtration.
2. Test your thermostat
Switch to Heat, set a few degrees higher than room temperature, and confirm the furnace starts and stops cleanly. If temperatures drift or cycling seems off, schedule service.
3. Clear supply and return vents
Move furniture and rugs away from registers and returns. Blocked vents strain the system and create comfort issues. Keep at least a few inches of clearance for steady airflow.
4. Inspect the intake and exhaust
If you have a high efficiency furnace with exterior PVC pipes, check for leaves, nests, or snow. Clear debris to prevent shutdowns and combustion issues.
5. Check carbon monoxide protection
Install CO alarms near every sleeping area and on each level. Test monthly. Replace batteries yearly unless you use sealed ten year units. Follow the manufacturer schedule for full unit replacement.
Remember that CO is odorless and colorless. Alarms are your first line of safety.
6. Clean the furnace area
Keep the space around the furnace clear. Remove storage, dust, and pet hair. A clean area improves airflow to the cabinet and reduces fire risk.
7. Schedule a professional tune up
A licensed technician should inspect heat exchangers, burners, ignition, safeties, and flue. Annual service improves reliability and can lower energy use. The U.S. Department of Energy recommends routine service before the season.
8. Seal drafts and set smart schedules
After your system is ready, cut heat loss at the source. Seal air leaks and use smart scheduling to avoid waste. ENERGY STAR lists maintenance and schedule tips that support comfort and savings.

When to call a pro now
Call if you smell gas. Call if you hear grinding or loud boom noises. Call if the furnace short cycles or the flame looks yellow. These signs point to safety or combustion problems that need expert care.
