How often should furnaces be inspected to reduce heating fire risk?

• A. Daily
• B. Annually
• C. Every five years
• D. Only when it breaks

Answer: (B)

Regular annual inspections by a qualified technician are essential to minimize heating fire risk. A yearly check catches issues before they become dangerous, such as cracks in the heat exchanger, dirty burners, loose gas connections, or blocked venting that could lead to dangerous gas buildup or fires. The technician tests ignition and safety controls, checks for proper fuel-to-air balance, and confirms there’s safe venting and adequate airflow. Cleaning and minor adjustments during maintenance reduce the chance of overheating or fuel-related hazards and help the system run safely and efficiently. You can support safety at home by keeping the area around the furnace clear of clutter and combustibles, and by changing filters monthly. If you ever smell gas, hear hissing, or notice soot or other signs of trouble, leave the area and contact the gas company or fire department.
