Performed annual maintenance on the oil-fired furnace, including a comprehensive inspection of all safety controls and system components to ensure safe and efficient operation in accordance with manufacturer specifications. Replaced the oil nozzle, oil filter, and strainer. Cleaned the furnace and smoke pipe by brushing and vacuuming. Conducted a combustion analysis and draft test, and inspected the heat exchanger.
