Oil Burner Cleaning Process

Here's How We Service Your System

Every oil burner service starts with a complete system inspection. Our technician examines your burner components, checks fuel lines, and tests safety controls to identify any issues before they cause problems.

Next comes thorough cleaning of the combustion chamber, burner nozzle, and heat exchanger. Clean components burn fuel efficiently and produce more heat with less waste. We also replace filters and adjust airflow for optimal performance.

Finally, the system gets tested and calibrated. You’ll see how everything works, understand what was done, and know exactly when your next service is due. Your oil burner runs cleaner, heats better, and uses less fuel.

Most oil burners need professional service once a year, typically before the heating season starts. Annual service includes cleaning the combustion chamber, replacing filters, checking safety controls, and testing system efficiency. If your oil burner is older than 15 years or has been having issues, you might benefit from twice-yearly service. Regular maintenance prevents most breakdowns and keeps your system running efficiently, which saves money on fuel costs and extends equipment life.
Watch for these common warning signs: unusual noises like rumbling or banging, yellow or smoky flames instead of blue, strong fuel odors, frequent cycling on and off, or uneven heating throughout your home. You might also notice higher fuel bills, soot around the unit, or the system struggling to reach your thermostat setting. Any of these symptoms means your oil burner needs professional attention. Ignoring these signs often leads to complete system failure and expensive emergency repairs.
A complete oil burner service typically takes 1-2 hours, depending on your system’s condition and any issues discovered during inspection. Routine maintenance on a well-maintained system usually takes about an hour. If repairs are needed or components require replacement, the service may take longer. Our technician will explain what needs to be done and give you a time estimate before starting any additional work beyond basic maintenance.
