Sizing a boiler for this county is a question about what the burner and heat exchanger carry across a long working season, not just how cold the single coldest week gets. Homes in Wheatland County, MT run heat about ten months a year, from September through June. The ignition system cycles, the heat exchanger expands and contracts, and the burner fires through nearly the entire calendar year. A unit that is undersized, or installed with shortcuts in the flue or the water connections, has almost no idle period in which those faults stay hidden. A contractor quoting a new boiler here has to get the load calculation right before anything else on the job matters.

Ductwork laid down for one heating system does not automatically carry the next one. Half the homes in Wheatland County, Montana were built in 1958 or earlier (2020-2024 ACS 5-year). That depth of vintage means the duct runs, trunk sizes, and branch layouts in a typical house here were configured around equipment that has since been replaced at least once, possibly more. A contractor installing a new boiler has to assess what those runs will actually deliver before the quote means anything, because a mismatch between the distribution system and the new unit shows up in the first heating season, not on paper.
What Gets Installed With a New Boiler

The boiler itself sits in a mechanical room, basement, or utility space and is the heart of the system. A contractor installs the heat exchanger, burner assembly, and circulation pump inside that unit. Those components take fuel in and push heated water out through the piping that feeds the rest of the house.
Radiators or radiant floor loops sit at the far end of that piping, room by room, and give off the heat where people actually live. Alongside the boiler, a contractor installs the expansion tank, pressure relief valve, and any zone valves needed to direct flow where the layout calls for it.
The drawing shows a representative layout, and a licensed contractor determines exactly which components and configurations apply to your home.

Licensing and Legal Requirements for HVAC Installation in Wheatland 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.
