A new system in Hardin has ten months of heat and two of cooling to handle
Winter nights here average 14°F from December through February. A new furnace or heat pump has to hold a house through that cold, night after night, from September clear through June. Summer only asks for two months of work, with afternoons around 82°F, but the same system needs to handle both jobs well.
Hardin has seen 84 winter storms and 91 damaging wind events over the past ten years, and across Montana about 18% of households lost power for at least 24 hours in 2024. A new install is a chance to plan for that, with a system and setup that can get back to work as soon as the power does.

Montana requires HVAC contractors to hold a state license.
That license is tied to the contractor, not to the job, so the same license has to cover whatever work they do in your home. 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 amount, so the contractor doing this job needs to hold the state license.
Most cities and counties in Montana also require a permit for this kind of installation, with an inspection once the work is done. That permit and inspection are separate from the state license. The license tells you the contractor was tested and is on record with the state. The permit and inspection are a local check on this particular job.

- When should I replace my HVAC system?
- Once it's breaking down more than once a season, or a contractor tells you the heat exchanger or compressor is failing, it's time to replace rather than repair. Age matters too. A furnace or air conditioner into its second decade is working harder to do the same job, and parts get harder to find. In Hardin, your heating system runs from September through June, so a failure hits during ten months a year when you actually need it. If you're weighing one more repair against replacement, ask the contractor how many years of service is realistic before you commit.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together makes sense, since a furnace and air conditioner installed at different times often don't match well and can end up working against each other. A mismatched coil and furnace can also void the warranty on the new unit. That said, if your air conditioner is only two years into its life and the furnace just failed, there's no reason to replace a unit that's working fine. A contractor can tell you whether your current AC and furnace are compatible enough to leave the working one alone.
- What happens during an HVAC installation?
- A licensed contractor removes the old equipment, sets the new furnace and air conditioner or heat pump, and connects it to your ductwork, gas line or electrical circuit as needed. They'll also pull the permit your local building office requires for this kind of job, since replacing a furnace or air conditioner isn't work you can have done without one. After the equipment is running, an inspector checks the work before it's signed off. Expect the contractor to test the system, check refrigerant charge and airflow, and walk you through the thermostat before they leave.
