Kalispell asks a lot of a heating system, most of the year
Winter nights here average 17°F from December through February, and homes need heat running from August through June. That is eleven months a year with the burner or the heat pump working, and only a short stretch in between where the system gets a rest. A new system sized for this has to hold up to that kind of use, not just handle a cold snap now and then.
Summer afternoons average 72°F, so cooling asks much less of the system here than heat does. Whatever gets installed still has to do both jobs, and it has to keep working through the outages this area sees. Montana households saw 18% go at least 24 hours without power in 2024, and over the ten years from 2015 to 2024 this area logged 124 winter storms and 69 damaging wind events. A furnace or heat pump is only as reliable as the power behind it.

Montana requires HVAC contractors to hold a state license.
The license is issued to the contractor, not the job. Montana's Department of Labor and Industry keeps that record, tested and on file, for the business doing the work, not for this particular install. Work under $2,500 falls outside the requirement, but a heating and cooling system installation runs well past that line, so the contractor doing it should hold the state license.
The license covers who is allowed to do the work. It does not cover whether the work gets checked once it is done. That comes from the local building office, which in most cities and counties requires a permit for this kind of installation and an inspection when it is finished.

- When should I replace my HVAC system?
- Replace it when repairs start happening every year, or when the system is old enough that a breakdown feels like a matter of time. In Kalispell that matters more than most places, since homes here need heat from August through June and a failure in the cold months is a real problem, not an inconvenience. If a contractor has already been out more than once this year, get a full inspection before the cold sets in rather than waiting for the next call.
- Should I replace my furnace and air conditioner at the same time?
- Not here, because most homes in Kalispell do not run air conditioning at all. Summer afternoons average 72°F, mild enough that cooling is not something most houses need. If your furnace needs replacing, that decision can stand on its own.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace or system in place, and connects it to the ductwork, gas or electric line, and venting. Once it's running, they test it and check that it's heating the way it should. In most cities and counties this work also needs a permit from the local building office, with an inspection after the job is done. Montana requires the contractor doing this work to hold a state license, and a contractor will price the job once they see the house.
