Long Island, Rockland County & Bergen County’s Oil Boiler Team
Long Island, Rockland County & Bergen County homeowners call Universe for oil boilers because oil heating has fuel-specific requirements that benefit from local experience.
Oil heating is not gas heating with a different nozzle. The combustion chamber runs hotter, soot accumulates differently, the oil tank and supply lines are part of the system in a way a gas line is not, and the annual tune-up is genuinely required rather than optional.
We have been servicing oil boilers across Long Island for decades, and we know the brands, the common failure modes, and the installation patterns specific to Long Island, Rockland County & Bergen County homes. When an oil boiler call surfaces related work at the tank, the flue, or the distribution system, we handle it in-house.

Why Work With Universe Home Services?
Our HVAC technicians are trained and experienced with oil boiler systems, including legacy equipment and current high-efficiency units common in older Long Island homes. Every service visit is handled by someone who knows the combustion side of oil heat, not just hydronic distribution.
An oil boiler failure on a January night is not a problem that waits for morning. We provide same-day service and 24/7 winter emergency response so heat is restored without homeowners sitting through a cold house and without the secondary risk of frozen pipes.
If replacement is the right call, whether with another oil boiler or a gas conversion, we provide free estimates on the work. You get real pricing and scope before making a decision that can shape your heating costs for the next 20 years.
Flexible financing with approved credit lets you spread installation costs over time, making a high-performance boiler or a full oil-to-gas conversion more accessible without stretching your budget.
We offer discounts for military personnel, veterans, and seniors, along with seasonal offers that keep service affordable for the households that most need oil heat to stay reliable.
With a skilled team across HVAC, plumbing, and electrical, we respond quickly when an oil boiler project surfaces related work, whether that is a circulator pump, an expansion tank, a new thermostat zone, or the gas line coordination that comes with a conversion.
Our repairs and installations are backed by warranties that ensure lasting quality and peace of mind. When we install a new oil boiler, we stand behind the work and the equipment.
Universe is a BBB Accredited Business. Seven decades of HVAC service across Long Island, Rockland County & Bergen County stands behind every oil boiler we install, repair, or maintain.

Your technician evaluates the boiler, the burner, the oil tank and supply lines, and the hydronic distribution side of the system. You receive a clear explanation of what was found and a written recommendation before any work begins, including whether oil-to-gas conversion is worth evaluating on this call or a future one.

Questions?
Oil Boiler Repair
Oil boilers share hydronic failure modes with gas boilers and add a full set of their own at the burner, the oil supply, and the combustion chamber.
Universe diagnoses and repairs oil boilers across Long Island, Rockland County & Bergen County, including the oil-specific problems that do not exist on gas systems. We can help with:
Oil boilers rely on a high-voltage ignition system to light the atomized oil spray in the combustion chamber. Misaligned electrodes, clogged or worn nozzles, a fouled cad cell, or a failing ignition transformer all cause weak flames, lockouts, or complete failure to fire. We correct the ignition system and restore reliable startup.
Worn seals, failing fittings, or cracked supply lines cause oil leaks that need prompt attention, both for the mess and for the fuel loss. We repair with precision replacements and pressure-test the connections to confirm the fix, and we inspect the oil tank itself while we are on site.
Relief valve issues, expansion tank problems, and circulator failures cause system pressure to drift or heat to stop moving through the zones. These are hydronic problems that show up on oil and gas boilers alike, and we correct them through component adjustment, purging, or replacement.
Soot buildup in the burner, the heat exchanger, or the flue passages reduces efficiency and, at the extreme, creates safety issues. Clogged oil filters and strainers cut fuel flow and starve the burner. We clean the combustion path, replace filters, verify flue draft, and restore proper fuel delivery as part of the repair.

Oil Boiler Maintenance
Annual maintenance is critical for safety and efficiency on oil boilers. It is not an optional service the way it sometimes is on gas.
Universe provides oil boiler maintenance across Long Island, Rockland County & Bergen County, with the annual tune-up scheduled before the heating season so the system is ready when the first cold night hits.
We calibrate the burner and clean the combustion chamber, heat exchanger surfaces, and nozzle assembly as part of every annual tune-up. Soot accumulates every season on oil heat, and the cleaning is what keeps combustion efficiency from drifting year over year.
Replacing the oil filter and the burner nozzle on an annual schedule prevents fuel flow issues and keeps the spray pattern in the combustion chamber correct. It is a small task with outsized impact on reliability and efficiency through the season.
Our technicians test pressure levels, safety controls, combustion readings, and flue draft to confirm the boiler is operating within safe limits and venting correctly. Safety testing is a core part of every oil boiler maintenance visit because the failure modes on oil are more varied than on gas.
We inspect the oil tank, supply lines, filter, shutoff, and tank vent for leaks, damage, or corrosion. Early detection of tank and line issues prevents the larger oil-handling problems and environmental issues that come from a neglected tank system.

Oil Boiler FAQs
How long do oil boilers last in Long Island homes?
With proper annual maintenance and prompt repairs, oil boilers often serve reliably for 20 to 30 years, which is longer than most gas boilers of the same generation. On Long Island, where oil heating has been the default in many neighborhoods for decades, we regularly service oil equipment that is 25 years old and still running, though efficiency drops noticeably past the 20-year mark.
Can I upgrade my old oil boiler to a more efficient model?
Yes. Today’s high-efficiency oil boilers integrate with existing oil tanks and supply infrastructure and deliver up to 85% AFUE or higher, which is a meaningful improvement over older units running in the 70% range. That cuts fuel consumption, improves comfort, and usually pays back through lower oil bills across the first several heating seasons.
What is included in an annual oil boiler tune-up?
A comprehensive tune-up includes burner calibration, cleaning the combustion chamber and heat exchanger, replacing the oil filter and burner nozzle, testing safety controls and flue draft, inspecting the oil tank and supply lines, and verifying system pressure. Oil boilers require this service annually because soot and combustion byproducts accumulate in ways they do not on gas equipment.
Should I consider converting from oil to gas?
That depends on whether natural gas is available at your home, what your current oil costs look like, and how much life is left in the existing boiler. Oil-to-gas conversion is a common Long Island upgrade when National Grid service has reached the street, and we can help you evaluate whether the conversion makes financial sense or whether staying on oil with a high-efficiency boiler is the better answer for your situation.
