Professional Oil Furnace Service

Reliable Heat When It Matters Most

Your oil burner works harder during New England winters than almost any other system in your home. When it’s running right, you don’t think about it. When it’s not, everything stops.

A properly maintained oil burner keeps your family comfortable while running efficiently. That means lower heating bills and fewer emergency calls on the coldest days of the year. You get consistent heat distribution throughout your home and the peace of mind that comes with knowing your system won’t leave you in the cold.

Regular oil burner cleaning and maintenance catch small problems before they turn into expensive repairs. Your system runs cleaner, lasts longer, and gives you the reliable performance you need to get through another Massachusetts winter without worry.

Oil Burner Repair Process

Straightforward Service That Gets Results

When you call for oil burner service, we start with a thorough diagnostic to identify exactly what’s wrong. Our technicians examine all the key components – the burner assembly, ignition system, fuel delivery, and safety controls – to pinpoint the root cause of any performance issues.

For routine maintenance, we clean the burner components, replace filters, check fuel lines, and test safety systems. This process typically takes about an hour and helps prevent most common heating problems before they start. We explain what we’re doing and why it matters for your system’s performance.

Emergency repairs get priority response because we know you can’t wait for heat in the middle of winter. We carry common replacement parts and have the diagnostic tools needed to get most systems running again quickly. After any repair, we test the system thoroughly to make sure everything is working properly before we leave.

Complete Oil Burner Services

Everything Your Heating System Needs

Our oil burner service covers the complete system, not just individual components. We handle burner cleaning, nozzle replacement, ignition system repair, fuel pump service, and control system diagnostics. When parts need replacement, we use quality components that will hold up to regular use.

Cohasset’s coastal location means your oil burner deals with humidity and salt air that can affect system components over time. We know which parts are most likely to need attention in this environment and how to prevent corrosion and buildup that reduce efficiency.

Oil burner installation requires proper sizing, ventilation, and safety system setup. We make sure new systems are configured correctly for your home’s layout and heating needs. Whether you need emergency repair or planned maintenance, we bring the right tools and parts to complete the job efficiently.

Most oil burners should be cleaned and serviced annually, ideally before the heating season starts in late fall. However, if you notice reduced efficiency, unusual odors, or frequent cycling, you may need service sooner. Regular annual maintenance prevents most breakdowns and keeps your system running efficiently. During a service visit, we clean the burner assembly, replace filters, check fuel lines, and test all safety controls. This routine maintenance typically extends equipment life and reduces heating costs by ensuring optimal combustion efficiency.
Common signs include the burner cycling on and off frequently, unusual noises during operation, visible smoke from the chimney, strong fuel odors, or uneven heating throughout your home. You might also notice higher than normal oil consumption or the system struggling to maintain temperature. If your burner won’t start at all, makes loud banging noises, or produces yellow flames instead of blue, these indicate more serious problems that need immediate attention. Don’t ignore these warning signs – addressing issues early usually means simpler, less expensive repairs.
Yes, our technicians work on all major oil burner brands and models, including older systems that other companies might not service. We have experience with residential oil burners from manufacturers like Beckett, Carlin, Riello, and Wayne.

Our experience with Norfolk County’s mix of older and newer homes means we’ve worked on virtually every type of oil heating system you’ll find in the area.
