Whole blocks of cape cods kept their oil burners through every gas-conversion wave, and the village's oil-delivery routes are as established as its gas mains. The stock is cast-iron hot-water boilers with pressure-atomizing burners : durable blocks, many 30-plus years old, with faults concentrated at the burner end.
The local pattern is deferred maintenance meeting the coldest nights. A nozzle overdue for replacement, a filter full of tank sludge, electrodes out of gap — each is a consumable, and each fails when the burner works hardest, which is the January week the will-call delivery is also hardest to schedule. In a market this oil-heavy, the triage runs burner-first by default: nozzle, electrodes, cad-cell sighting, filter, fuel line, tank — in that order. If your home is one of the village's oil holdouts, say so early on the call; it routes you to oil-specific questions immediately.
