A contractor diagnosing a boiler failure here has to weigh age and upkeep against weather load before settling on a cause. 91 severe weather events were recorded in Hancock County, Indiana between 2015 and 2024. That puts Hancock County in a middle range, where severe weather is real but not the standing pressure that explains most breakdowns. Heat exchangers crack, pressure vessels corrode, and controls fail on schedules driven mainly by how well the system was installed and serviced. A contractor who opens a boiler here and finds a failed component has to ask when it was last serviced before pointing at the weather.
Boilers in a county with housing stock this old accumulate sediment in the heat exchanger, corroded fittings at the zone valves, and seals that have cycled through enough heating seasons to fail in ways that look identical from the outside and turn out to be very different once the unit is open. Half the homes in Hancock County, Indiana were built in 1991 or earlier (2020-2024 ACS 5-year). That spread matters for repair: a contractor working in stock this age quotes a job after opening the system, not before, because what looks like a pressure relief issue can be a cracked heat exchanger, and the two carry different parts, different labor, and a different conversation about whether the repair is worth finishing.
The Parts of a Boiler a Contractor Checks First
The boiler itself sits in the basement or a mechanical room and is the unit that heats water for the whole system. When it fails, the signs point there first: no heat, strange sounds, or water pooling near the base. The heat exchanger inside it and the burner assembly are the pieces a contractor examines closely.
From the boiler, pipes carry hot water to radiators or baseboard units in each room, and those terminal units are where the heat actually reaches the living space. The circulator pump, mounted on the supply or return line, keeps water moving through that loop. The expansion tank and pressure relief valve sit near the boiler and protect the system if pressure builds.
The drawing shows a typical boiler layout, and a licensed contractor determines which components apply to the specific system in your house.

Boilers work hardest when outdoor conditions swing hard, and the stress those swings put on a heating system is specific to where you live. That workload pattern is a local fact, and it shapes how often repair needs come up.
