Oil Burner Repair & Service Experts — Long Island
Oil heat remains one of the most common heating fuel sources across Long Island, particularly in older neighborhoods throughout Nassau and Suffolk County. When your oil burner fails — or performs poorly — it affects your comfort, your fuel bills, and your safety. Our licensed technicians provide fast, honest oil burner repair and tune-up service throughout the Island.
We service all residential oil-fired systems: oil furnaces, oil boilers, combination systems, and steam boilers. Our trucks carry common nozzles, filters, igniters, and burner parts for Beckett, Carlin, Riello, and Wayne burners — the brands most commonly found in Long Island homes — so we can complete most repairs on the first visit.
Whether your burner has locked out, is cycling frequently, or simply hasn't been serviced in years, we can diagnose the problem, restore efficiency, and extend the life of your system.
Signs Your Oil Burner Needs Service
- ✓No heat or weak heat output from your system
- ✓Oil burner goes into lockout mode and won't stay running
- ✓Sooty buildup around the unit, registers, or on walls
- ✓Burning smell, smoke, or visible soot when the burner fires
- ✓Burner cycling on and off frequently without reaching temperature
- ✓Unusual rumbling, puffing, or banging sounds when the burner ignites
- ✓Oil consumption noticeably higher than previous seasons
- ✓System hasn't been professionally serviced in more than 12 months
Annual Oil Burner Tune-Up — What's Included
An annual tune-up is the single most effective way to protect your oil heating system. Here's what our technicians perform on every service visit:
- ✓Nozzle replacement — worn nozzles cause poor combustion and higher fuel use
- ✓Oil filter replacement — prevents sediment from reaching the burner
- ✓Electrode cleaning and gap adjustment — ensures reliable ignition
- ✓Heat exchanger inspection for cracks or deterioration
- ✓Flue gas analysis to measure combustion efficiency and CO output
- ✓Safety control testing — aquastat, limit switch, primary control
- ✓Fuel line and oil pump pressure check
- ✓Combustion chamber inspection and cleaning
Oil Heating Systems We Service
Long Island homes use a variety of oil-fired heating systems. We work on all of them:
- ✓Oil-fired forced air furnaces — the most common system in newer Long Island homes
- ✓Oil-fired hot water boilers — prevalent in mid-century homes throughout Nassau and Suffolk
- ✓Oil-fired steam boilers — found in older homes, especially pre-1960 construction
- ✓Combination systems — oil boiler with domestic hot water coil
- ✓Tankless coil systems integrated with oil boiler
Oil Tank Inspection & Safety
Your oil tank is as important as your burner. Above-ground tanks typically last 20–30 years, but signs of trouble — rust, soft spots, oil smell around the tank, or corrosion at fittings — should never be ignored. A leaking tank is both a fire hazard and an environmental liability.
Underground oil storage tanks (USTs) present additional complexity on Long Island. Many homes built before the 1980s had underground tanks that may still be in place. NYSDEC regulations require that decommissioning an underground tank be performed by a licensed contractor with the appropriate Suffolk County permit. If there is any evidence of a leak, a site assessment is required before the tank can be closed.
If you're buying or selling a home and an underground tank is involved — or if you're simply unsure whether your property has a buried tank — we can advise you on the right steps. Acting early avoids far costlier remediation down the road.
Thinking About Oil-to-Gas Conversion?
Converting from oil to natural gas is a significant decision for Long Island homeowners. The upfront cost typically ranges from $5,000 to $15,000, depending on whether gas is available at the street, the length of the gas service line needed, and whether you're replacing the heating equipment entirely or just the burner.
Gas tends to have lower fuel costs per BTU than oil on Long Island, but the payback period on the conversion investment varies widely by home size and fuel price fluctuations. For some homeowners it makes strong financial sense; for others — particularly those who may sell within a few years — the math doesn't always work out.
We're happy to talk through the specifics of your home and give you an honest picture of what conversion would involve. If you'd like to discuss whether oil-to-gas conversion makes sense for your situation, give us a call.
