The postcard arrives in August, or the oil company leaves a note on the door: your burner is due for its cleaning. It is easy to put off when the house is 80 degrees. But that visit is what keeps a burner lighting cleanly instead of sooting up and locking out in the middle of winter.
Oil is the heating fuel of Long Island. Census figures compiled by Molloy University put oil heat in roughly 59 of every 100 Long Island homes. That means the oil burner, the motor, pump and nozzle bolted onto the front of the boiler or furnace, is the machine in most Long Island basements.
Inside an annual oil burner cleaning
All Island Comfort spells out what its annual tune-up covers, and it is a good checklist to hand any company:
- Replace the nozzle, with the right size and spray pattern for your unit.
- Replace the oil filter.
- Clean the pump strainer.
- Tune draft, smoke and CO2.
- Run a digital combustion analysis to document efficiency.
- Leave a written report of anything flagged.
They say it takes about 60 to 90 minutes. Beckett’s manual backs up the parts list: it says the line filter cartridge must be replaced to keep the fuel unit and nozzle from getting contaminated, and that a replacement nozzle should match the exact specifications the appliance maker calls for.
If a visit is far shorter than that and leaves no combustion numbers, ask what was skipped.
When to book it
All Island Comfort recommends late summer or early fall, ahead of the first cold night the burner has to run. Their rule of thumb: if more than 14 to 18 months have passed since the last tune-up, you are due. Beckett’s manual goes further and requires a yearly visit by a qualified technician.
Signs the burner needs a visit now
Don’t wait for the annual date if you see any of these. They come from All Island Comfort’s service page.
- Yellow flame tips, soot or smoke. They mean incomplete combustion and wasted fuel. A clean burner runs blue and steady.
- Soot or smoke around the unit. All Island Comfort says that can be a sign it is time to evaluate replacement.
- Pressing the red reset button more than once a season. Something is wrong, and resetting it again is not the fix.
Press the reset button once. If the burner locks out again, stop there. Beckett tells owners never to fire or reset a burner while oil or oil vapor is sitting in the appliance, and some of its lockout states are meant to be cleared only by a qualified technician.
Burner brands Long Island techs work on
All Island Comfort lists Beckett, Riello, Carlin and Wayne as the burners its technicians are trained on. If you know your burner’s brand and model, give it to the company when you call.
Why prices are rarely posted
Neither Long Island company cited on this page posts an oil tune-up price. All Island Comfort says to ask for current maintenance plan pricing. Service Experts in Hampton Bays posts a standard $189 tune-up, but excludes oil furnace and boiler tune-ups from it and asks you to call.
On the phone, ask for the price, whether a new nozzle and filter are included, and whether you get the combustion test printout.
Assistance and safety rules that apply
HEAP has a Clean and Tune benefit on the books, but New York’s 2025-2026 state plan did not fund it, per OTDA’s January 14, 2026 memo to county social services offices. Check with your county HEAP office before counting on it this season.
While the technician is there, check your carbon monoxide alarm. Since February 22, 2010, state law has required a CO alarm in any one or two-family house that has fuel-burning equipment, and an oil burner counts.
