Maintenance on an oil boiler or furnace is recommended how often?

• A. Monthly
• B. Year
• C. Weekly
• D. Decade

Answer: (B)

Maintenance on an oil-fired boiler or furnace should be done annually by a qualified technician. Oil burners operate with combustion processes that can gradually accumulate soot, wear the nozzle, affect fuel delivery, and affect venting. A yearly service cleans and tunes the burner, inspects the heat exchanger and vent system, checks safety controls and carbon monoxide detectors, tests combustion efficiency, and replaces filters or worn components as needed. Regular annual servicing helps maintain efficiency, lowers fuel use, and reduces the risk of dangerous leaks or breakdowns, especially in cold weather. Monthly or weekly maintenance isn’t typically required, and waiting years between services can lead to inefficiency or safety issues.
