Homes in Herkimer County, NY run heat about nine months a year, from September through May. A boiler cycling through that kind of season puts its heaviest wear on the burner assembly and the ignition system, both of which fire and rest hundreds of times before spring arrives. When a contractor opens a unit for repair, those are the components that show the load first: cracked igniters, worn electrodes, heat exchanger fatigue from repeated thermal expansion. A homeowner who waits until a cold morning to call is handing the contractor a unit that has already run hard for months with whatever fault it developed.

A boiler serving a house in this county has often outlasted the supply chain built around it. Half the homes in Herkimer County, New York were built in 1954 or earlier (2020-2024 ACS 5-year). That means a contractor opening a failed unit is frequently working with components whose replacement parts require sourcing outside standard distributor stock, not pulling from a current catalog. Seals, heat exchangers, and burner assemblies for systems of that generation are stocked selectively if at all. The repair scope, and whether a repair is even viable, turns on what the opened unit actually contains.
The Parts of a Boiler a Contractor Checks First

The boiler itself sits in the basement or a mechanical room and is the piece a contractor goes to first. It heats water and pushes it out through the system. When it fails, the signs range from no heat at all to strange sounds, pressure problems, or a unit that short-cycles and shuts off before the house warms.
Radiators or baseboard units sit throughout the living spaces and release that heat into each room. The circulator pump, mounted on the boiler or the pipes near it, moves water through the loop. The expansion tank, pressure relief valve, and aquastat are smaller parts that sit close to the boiler and each one can be the source of a problem when the main unit tests out fine.
The drawing shows a typical boiler layout, and a licensed contractor determines which parts apply and what condition they are in for your specific home.

Extreme weather puts real hours on boilers. Every hard freeze, power surge, or pressure swing a storm brings is a load the equipment absorbs, and that accumulated stress is what drives repair work in the years that follow.
