A furnace contractor working a repair in Dickinson County has to sort out how much of what they find is wear from age and how much came from the weather this equipment has been running against. 108 severe weather events were recorded in Dickinson County, Michigan between 2015 and 2024. At that rate, components like heat exchangers, ignitors, and pressure switches have been cycling under real stress, and a contractor who skips that history risks misreading why a part failed. The diagnosis shapes the repair: a stress-worn ignitor replaced in isolation will likely fail again if the underlying load pattern goes unaddressed.
Ductwork in a house this old was put in for whatever the original heating system was, but the furnace sitting in it now is almost certainly not that system. Half the homes in Dickinson County, Michigan were built in 1970 or earlier (2020-2024 ACS 5-year). When a contractor opens a furnace that has been running in stock like this, the question that shapes the bill is whether the failed component still has a supply chain behind it. A heat exchanger or a control board on a system of that age may exist only in old stock or not at all, which turns a straightforward repair into a sourcing problem before it is anything else.
The Parts of a Furnace a Contractor Checks First
The furnace itself sits in the basement, utility room, or closet and is the piece a contractor goes to first. Inside it, the heat exchanger is the part most likely to be at the root of a heating failure or a safety concern. The burners, which fire inside that exchanger, are another early stop.
The blower motor sits within the furnace cabinet and pushes conditioned air into the supply side of the house. The flue, which runs from the furnace up and out of the building, carries combustion gases away. The thermostat on the wall is often where a diagnostic starts, because a wiring or calibration fault there can mimic a mechanical failure deeper in the system.
The drawing shows the general layout of a furnace system, and a licensed contractor determines what applies to the specific equipment and configuration in your home.
