Oil Burner Service and Repair for Homes and Landlords
Yes, we service oil burners across Patchogue. We diagnose oil-fired boilers and warm-air furnaces, prime supply lines after a runout, and carry out filter, nozzle, and electrode work. Call (631) 239-3871 and describe the system behavior.
Most no-heat calls trace to a short list of causes, and identifying which one applies determines how urgent the visit is. A tripped switch is a two-minute correction. A cracked heat exchanger is a significant repair. We diagnose the fault before recommending any work.
Common Causes of No Heat in an Oil-Fired System
| Symptom | Likely cause |
|---|---|
| Burner completely silent | Power off at the switch or breaker, a failed control, or a thermostat fault |
| Burner hums then locks out | Air in the line after a runout, a clogged filter, or a failed pump |
| Burner fires then cuts out quickly | Dirty cad cell, weak ignition, or a nozzle that is not atomizing properly |
| Rumbling or delayed ignition | Worn nozzle, incorrect air-band setting, or fouled electrodes |
| Soot, smoke, or a sooty smell | Incomplete combustion, restricted flue, or overdue service |
| Some rooms warm, others cold | Circulation or distribution issue rather than the burner itself |
What Happens After a Runout
A dry tank is the most common reason for a burner service call. Once the oil level drops below the pickup, the pump draws air and the primary control locks the burner out on safety. Adding fuel does not clear the lockout. The line must be primed and bled to expel the air, and because the lowest inches of a tank hold accumulated sediment and water, the filter and strainer normally require attention at the same time. Once fuel flow is clean and stable, we check the nozzle and electrodes, re-establish flame, and confirm the system holds through a full cycle before leaving.

Annual Oil Burner Maintenance
Booked before the season starts, a maintenance visit is straightforward and predictable. Typically it covers replacing the oil filter and nozzle, cleaning or replacing the strainer, checking and setting electrodes, inspecting the cad cell and primary control, checking the flue and draft, and adjusting combustion so the system runs to specification.
A burner operating with a partly clogged nozzle consumes additional fuel every hour it runs, and most faults that cause a mid-winter failure are detectable during an autumn service. Booking before the heating season also allows a scheduled appointment rather than one arranged around emergency calls.
When to Call Straight Away
- You smell oil strongly in the basement or see fuel around the burner or tank
- The burner has locked out more than once in the same day
- There is visible soot around the unit or a smoky smell through the house
- The tank shows rust streaks, weeping seams, or damp patches underneath
- Heat has failed in freezing weather and pipes are at risk
If you smell oil strongly or see smoke, shut the system off at the emergency switch before you call.
Oil Burner Service and Repair Questions
The questions we are asked most often about this service.
My oil burner will not start. What should I check first?
Check three things before calling. Is there oil in the tank? Is the emergency shut-off switch, usually at the top of the basement stairs or beside the unit, still on? Has the breaker tripped? If all three are fine, press the reset button once and once only. If it locks out again, stop and call us.
Why does my burner keep locking out after a refill?
Because the fuel line still has air in it, or because sediment drawn from the bottom of the tank has restricted the filter or nozzle. After a runout the line normally needs priming and bleeding, and the filter often needs replacing before the burner will hold a stable flame.
How often should an oil burner be serviced?
Once a year, ideally before the heating season starts rather than during it. Annual service typically covers the filter, nozzle, strainer, electrodes, and combustion settings, and it is the cheapest way to find a failing part in September instead of on the coldest night of January.
What does an oil burner service call cost?
The cost depends on the fault, which is why we diagnose before quoting. The problem and the work required are explained before anything begins. Call (631) 239-3871 to describe the symptoms.
Do you service the burner if I did not buy the oil from you?
Yes. Burner service is available whether or not you buy fuel from us. Provide the make of the boiler or furnace and a description of the fault when you call.
What is the black smoke or soot smell coming from my burner?
This normally indicates incomplete combustion, which can result from a clogged nozzle, a restricted filter, an air-band setting that has drifted, or a flue obstruction. It should not be left through the season. Soot coats the heat exchanger, increases fuel consumption, and can indicate a venting fault.
