What a system in Stillwater County has to handle
Your furnace is the machine doing most of the work here. Winter nights average 15°F from December through February, and homes in this county need heat from September clear through June, ten months of the year. That is most of a year of the burner cycling on cold nights. The equipment going in has to be sized and installed to keep up with that whole stretch, not just the coldest week of it.
Cooling only really matters in July, when afternoons average 78°F, so the air conditioner has a short season and a lighter job. Montana also sees weather that works against a system already under strain. Stillwater County has recorded 160 winter storms and 112 damaging wind events over the past ten years. In 2024, 18% of Montana households lost power for a full day or more. That matters when you're choosing new equipment. A furnace with a standing pilot will still light without power. One with electronic ignition won't run until the power is back on.

Montana requires HVAC contractors to hold a state license.
The state license is tied to the contractor, not to any single job, so it stays on record with the Department of Labor and Industry no matter how many installs a company has done. Work under $2,500 falls outside that requirement, but a heating and cooling system install runs well past that threshold, so the contractor doing this job needs to hold the license.
Beyond the license itself, the permit is what puts a second set of eyes on the work. Most cities and counties in Montana require a permit for this kind of installation, along with an inspection once it's finished, and that inspection is what confirms the gas and electrical connections were done right.

- When should I replace my HVAC system?
- Replace it when repairs start piling up or the unit is old enough that the next breakdown is a matter of when, not if. Parts get harder to find as a furnace or air conditioner ages, and a contractor called out for a repair can usually tell you whether the unit is worth fixing again. Homes here need heat from September through June, so a furnace going out is not something to leave until it fails. If your energy bills have crept up with no other explanation, that is often a sign the equipment is working harder than it should.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, and there is a practical reason for it. A furnace and air conditioner installed together are matched to work as one system, and pairing an old unit with a new one can mean the new one never runs the way it was built to. It also means one installation and one inspection instead of two separate jobs later. If one unit is much newer than the other and still running well, there is no reason to replace something that is not the problem. A contractor can look at both and tell you honestly whether they are close enough in age to make replacing them together worth it.
- What happens during an HVAC installation?
- A contractor removes the old furnace or air conditioner and any parts that will not work with the new one, then sets the new equipment in place and connects it to the ductwork, gas line or electrical circuit, and refrigerant lines. Once it is connected, they run it through a full cycle to check airflow, temperature and pressures. Installing a heating and cooling system needs a permit from the local building office in most cities and counties, along with an inspection once the work is done. A contractor pulling that permit is part of the job, not something you need to arrange yourself.
