The gun burner is the precision instrument of oil heat — a nozzle misting oil into a fine spray, electrodes sparking it, a flame that should burn clean and steady. In Flushing’s cramped tank rooms that instrument breathes basement air thick with decades of dust, fires into boilers old enough to vote, and gets serviced in spaces where the pro works by flashlight. The annual pre-season service — nozzle, filter, electrodes, combustion check — matters more here, not less.
When burners fail, the story is usually unglamorous: a fouled nozzle collapsing the spray pattern, electrodes worn and drifted giving weak spark and delayed ignition (sometimes with a startling puffback), a filter choked with the sediment every old tank grows. The visit works that chain methodically — tank and gauge, filter, burner internals, combustion — and reports back in plain language: what stopped, why, and what’s aging toward the same fate. On-site pricing comes from the local pro after the system has been seen and tested; the triage call is free.
