Homes in Deer Lodge County, MT run heat in every month of the year. A boiler that fires every month of the year puts steady wear on its burner assembly, heat exchanger, and ignition components rather than getting a long stretch of dormancy to hide minor faults. When a contractor opens a unit here, the ignition system and burner are the first things checked, because those are the parts that have been working without a break. A heat exchanger showing fatigue on a relatively young boiler is not a surprise in this county.
Half the homes in Deer Lodge County, Montana were built in 1954 or earlier (2020-2024 ACS 5-year). A boiler sitting in a house that old has often outlasted multiple rounds of smaller repairs, and what a contractor finds once the unit is open tells a different story than what the service call described. Cast-iron sections crack in ways that show up only under pressure. Original flue connections corrode from the inside. Parts for systems that have been running since the postwar decades are not stocked locally and some are not made at all, which means a contractor has to identify exactly what is in that basement before any repair can be scoped or priced.
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 through the system. When heat stops reaching a room or stops reaching any room at all, the burner assembly, heat exchanger, and pressure relief valve inside the boiler are where a contractor begins.
From the boiler, supply pipes carry hot water to radiators or baseboard units mounted along the walls of each room, and return pipes bring the cooled water back. The circulator pump, which keeps that water moving, and the expansion tank, which absorbs pressure changes in the loop, both live close to the boiler and are common stops on any diagnostic visit.
The drawing shows the general layout of these components, and a licensed contractor determines what applies to the specific system in your house.

Licensing Rules for HVAC Repair in Deer Lodge County, Montana
Montana’s contractor licence does not reach a casual, minor or inconsequential job whose total price for labour, materials and everything else is less than $2,500 — and the exemption is lost if the work is only part of a larger operation, or if a job is divided up to get under the figure.
Montana requires a current construction contractor licence from the Department of Labor and Industry: an individual or business may not engage in business as a construction contractor without one.
