Complete Oil Burner Solutions

Everything Your System Needs

Our oil burner service covers the full range of what these systems require – from routine cleaning and maintenance to emergency repairs and complete installations. We handle burner tune-ups, nozzle replacements, filter changes, and combustion chamber cleaning.

Many Mattapoisett homes have oil systems that are 15-20 years old or more. These systems can run reliably for decades with proper care, but they need technicians who understand their specific requirements and common failure points.

Whether you need annual maintenance through our Dempsey Comfort Club, emergency repair service, or guidance on whether to repair or replace an aging system, we provide honest assessments based on what makes sense for your situation and budget.

Most oil burners should be serviced annually, ideally before the heating season begins in late fall. Annual service includes cleaning the burner, replacing filters, checking the combustion chamber, and testing safety controls. If your system is older or has been having issues, you might benefit from twice-yearly service. Regular maintenance prevents most emergency breakdowns and keeps your system running efficiently, which saves money on fuel costs and extends equipment life.
Common warning signs include unusual noises like rumbling or banging, yellow or smoky flames instead of blue, strong fuel odors, frequent cycling on and off, or higher than normal fuel consumption. You might also notice uneven heating, soot around the unit, or error codes on newer systems. If you smell fuel or see smoke, shut off the system immediately and call for service. Many of these issues start small but can become expensive problems if ignored, so it’s better to have them checked sooner rather than later.
Yes, we work on oil burners of all ages, including older systems that many companies won’t touch. Older oil burners can often be maintained and repaired effectively for many years with the right expertise. We keep common parts for older systems in stock and can often find parts for discontinued models. However, we’ll give you honest advice about when an older system has reached the point where replacement makes more financial sense than continued repairs.
Yes, we understand that heating emergencies don’t wait for convenient times. We provide emergency oil burner repair service because we know how quickly a heating failure can become a serious problem, especially during cold weather. Our technicians are equipped to handle most common emergency repairs and can often restore heat the same day. Emergency service is prioritized for Dempsey Comfort Club members, but we respond to all emergency calls as quickly as possible.
Complete oil burner maintenance includes cleaning the burner assembly, replacing the oil filter and nozzle, checking and adjusting the combustion settings, testing safety controls, inspecting the heat exchanger, and cleaning the combustion chamber. We also check the chimney draft, test carbon monoxide levels, and inspect all electrical connections. After service, we test the system to ensure it’s operating safely and efficiently. You’ll receive a clear report of what was done and any recommendations for future maintenance or repairs.
This depends on the age of your system, the cost of needed repairs, and its overall condition. Generally, if repair costs exceed 50% of replacement cost, or if your system is over 20 years old and needing frequent repairs, replacement often makes more sense. However, a well-maintained older system can sometimes be worth repairing. We’ll assess your specific situation and give you honest recommendations based on the repair costs, your system’s condition, and potential energy savings from a newer, more efficient unit.
