Expert oil system maintenance, tank services & 24/7 emergency repair across Nassau County
Nassau County has one of the highest concentrations of oil-heated homes in the country. Tens of thousands of homes across Levittown, Hicksville, Hempstead, and surrounding communities still rely on oil burners and oil-fired boilers installed in the 1960s through 1990s. These systems require specialized annual maintenance — including nozzle and filter replacement, combustion chamber cleaning, and efficiency testing — that general HVAC contractors often skip or perform inadequately. Home+ Air & Heat provides comprehensive heating oil service across Nassau County, from routine tune-ups to emergency no-heat calls and oil tank inspections. We understand oil heating systems because we work on them every day, not as an afterthought to our gas and electric business.
Oil heating systems operate under fundamentally different principles than gas furnaces or heat pumps. The combustion process involves atomizing fuel oil through a precision nozzle at high pressure, igniting it with electrodes, and managing the resulting flame to maximize heat transfer while minimizing soot, carbon monoxide, and fuel waste. When any component in this chain degrades — a worn nozzle, dirty electrodes, a failing fuel pump, or a cracked combustion chamber — efficiency drops and safety risks increase. Our technicians carry combustion analyzers on every oil service call, measuring stack temperature, CO2 levels, smoke number, and draft to ensure your system meets manufacturer specifications and local safety codes. This approach catches problems before they become emergencies.

Don't wait for a breakdown — catch these warning signs early
Black soot around the burner, on walls near registers, or on furnace/boiler surfaces indicates incomplete combustion — a worn nozzle, misaligned electrodes, or air-to-fuel ratio problems that waste oil and create safety hazards.
If you're burning more oil than previous seasons with similar weather, your system is losing efficiency. Degraded nozzles spray imprecise fuel patterns, and dirty heat exchangers can't transfer heat effectively, sending energy up the chimney.
A persistent oil odor near your furnace, boiler, or tank often signals a fuel line leak, failed gasket, or cracked combustion chamber. This is both a fire hazard and an air quality concern that warrants immediate professional inspection.
An oil burner that repeatedly locks out and requires you to press the reset button is experiencing ignition failures. Each failed attempt floods the chamber with unburned oil, dramatically increasing puffback risk. Stop resetting and call for service.
Above-ground steel tanks are the most common in Nassau County. Standard residential tanks hold 275 gallons and have a typical lifespan of 20-30 years depending on location and maintenance. We inspect for exterior rust, seam integrity, leg stability, and vent/fill pipe condition. When replacement is needed, we handle both removal of the old tank and installation of the new one, including all connections and code compliance.
Underground oil tanks present unique challenges and regulatory requirements in Nassau County. Abandoned underground tanks must be properly decommissioned to prevent soil and groundwater contamination. If you have — or suspect you have — a buried oil tank, we can perform tank location services, soil testing, and coordinate with environmental consultants for proper remediation. New York State requires reporting of underground tank removals to the DEC.
For homeowners whose tanks are reaching end-of-life, this is often the ideal time to evaluate conversion options. Rather than investing $2,000-$4,000 in a new oil tank, you may find that converting to natural gas (if available on your street) or installing a heat pump system makes better long-term financial sense. Federal tax credits of up to $2,000 for heat pump installations and PSEG Long Island rebates of up to $1,000 can offset conversion costs significantly. We provide honest assessments — if maintaining oil makes more sense for your situation, we'll tell you.
Nassau County's housing boom of the 1940s through 1970s coincided with an era when oil was the dominant heating fuel on Long Island. Entire communities — Levittown, Hicksville, East Meadow, Wantagh, Bellmore — were built with oil-fired heating as standard equipment. While many homes have since converted to natural gas, thousands of Nassau County residences still rely on oil heat, particularly in neighborhoods where natural gas mains were never extended or where homeowners have maintained well-functioning oil systems. These aging systems require technicians who understand Beckett, Riello, and Carlin burners; who know the difference between a Honeywell R8184 and an R7284 primary control; and who can diagnose problems by the sound of ignition and the color of exhaust. That's the kind of oil heating expertise we bring to every service call.
Oil systems are less forgiving than gas systems when maintenance is neglected. A gas furnace with a dirty filter may lose efficiency gradually; an oil burner with a worn nozzle can experience a catastrophic puffback — an explosion of accumulated unburned fuel in the combustion chamber that can blow open the furnace door, coat your home in soot, and damage the heat exchanger beyond repair. Annual oil tune-ups aren't optional — they're essential safety maintenance. The nozzle, oil filter, and strainer are consumable components designed to be replaced every year. The electrodes that ignite the fuel degrade over time. The combustion chamber develops cracks from thermal cycling. Our standard $299 tune-up addresses all of these components and includes a combustion analysis to verify your system is operating within safe, efficient parameters.
We understand that many Nassau County homeowners with oil heat are thinking about conversion — whether to natural gas, a heat pump, or a hybrid system. The economics of conversion depend on factors like your current system's age and condition, whether natural gas is available on your street, your home's electrical capacity for a heat pump, and available incentives. While you evaluate your options, we'll keep your oil system running safely and efficiently. And when you're ready to make the switch, we offer oil-to-gas conversion, furnace-to-heat-pump conversion, and hybrid heating system installation — so you're not dealing with separate contractors for service and conversion. This continuity means we already know your home's heating infrastructure when it's time to plan the upgrade.

"Our oil burner kept locking out every few hours. They found a cracked nozzle and worn electrodes, replaced both, and did a full tune-up. System has been running perfectly all winter. Fair price and honest service."
"Scheduled an oil tune-up before winter. The technician replaced the nozzle and filter, cleaned the chamber, and showed me the combustion readings before and after. Night and day difference in efficiency. Very professional."
"Called at 11pm when our oil heat stopped working in January. They were here by 1am, diagnosed a failed cad cell, and had the part on the truck. Heat was back on within an hour. No emergency upcharge either."
