A Butte system needs to handle eleven months of heat, most of it cold
Winter nights in Silver Bow County average 14°F from December through February, and homes here need the furnace running from August through June. That's eleven months a year of work, with only a short stretch where the system gets to rest. Summer afternoons average 73°F, mild enough that cooling barely factors in, so the furnace is what has to be sized and installed right.
Most homes here heat with gas, and whatever system goes in has to hold up through that many months of cold starts. The county has logged 49 winter storms over the past ten years, and statewide, 18% of households lost power for 24 hours or more in 2024. A new system should be installed with that in mind, not just the average night but the ones that knock the power out.

Montana requires HVAC contractors to hold a state license.
Montana licenses HVAC contractors through the Department of Labor and Industry. The license is held by the contractor, not issued job by job, so the same license covers this installation and whatever else that contractor takes on. Montana does carve out one exception. Work under $2,500 does not need a licensed contractor. An installation of a heating and cooling system runs well past that line.
Because this job is licensed, that license is what stands behind the work. Most cities and counties in Montana also call for a permit from the local building office when a furnace, air conditioner or heat pump gets replaced, along with an inspection once the work is finished. That inspection is where a bad gas connection or a wiring mistake gets caught before the system ever runs.

- When should I replace my HVAC system?
- Replace it when repairs get frequent, the unit is old, or it can't keep up on the coldest nights anymore. A furnace running most of the year, like the ones here from August through June, wears faster than one that only kicks on a few months a year. If yours is limping through winter with 14°F nights outside, a contractor can tell you whether another repair makes sense or whether it's time for a new system.
- Should I replace my furnace and air conditioner at the same time?
- Not necessarily here. Homes in Butte don't need cooling, so most of the year's work falls on the furnace alone, and that's the unit that matters most. If you do have an air conditioner and it's near the end of its life too, replacing both at once can make sense, but a contractor can look at each unit's condition and tell you if pairing them makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace or system in place, and connects it to your ductwork, gas line or electrical circuit as needed. They'll check the venting, test the system for proper operation, and make sure it's sized right for your house. In most areas this work needs a permit from the local building office and an inspection once it's done, so the contractor handling your installation should be pulling that permit as part of the job.
