Red Lodge asks a lot of a heating and cooling system
Winter nights here average 15°F from December through February, and the heat has to hold against that for months at a stretch. Homes in Red Lodge need heat from September through June, ten months out of the year. Summer only asks for cooling in July, when afternoons average 76°F, but a new system still has to cover both jobs.
That is eleven months where the system is doing something. A furnace or heat pump sized for this place needs to keep up on the coldest nights, not just the average ones. This area has also logged 189 winter storms and 47 damaging wind events over the past ten years, and power does not always hold through them. Statewide, 18% of households went at least a full day without power in 2024. A new system installed here should be matched to what the winters actually do, not just to the house it is replacing.

Montana requires HVAC contractors to hold a state license.
The license is held by the contractor, not issued job by job, so it is the business itself that Montana has on record with the Department of Labor and Industry. Work under $2,500 falls outside that requirement, but a heating and cooling system installation runs well past that mark, so the contractor doing this job needs the license.
Because Montana's rule covers the contractor, the second check on this job comes from the local building office. Most cities and counties require a permit for a furnace, air conditioner or heat pump installation, and an inspection once the work is done, which is what confirms the gas and electrical connections were done right. That inspection is the part that catches what the license alone does not.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than they're worth, or when the unit is old enough that another breakdown feels like a matter of time, not chance. A furnace here works hard for ten months of the year, with winter lows averaging 15°F, so it doesn't get much of a break. If yours is limping through its second decade and you're already calling for repairs each winter, waiting for a full failure just means doing it in the cold instead of on your schedule.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, it usually makes sense to do them together. They're built to work as one system, and a mismatched pair, an old furnace paired with a new air conditioner, can end up running less efficiently than either would on its own. Homes here only need cooling in July, so the air conditioner sees far less wear than the furnace does. If your furnace is failing and the air conditioner still has good years left in it, replacing just the furnace is a reasonable call. A contractor can look at the age and condition of both and tell you whether pairing them makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace or air conditioner in place, and connects it to the ducts, gas line or electrical circuit, and the vent or flue it needs. They test the system to make sure it fires up, reaches temperature, and shuts off the way it should. Replacing a furnace or air conditioner needs a permit from the local building office in most places, along with an inspection once the work is done. That inspection is what confirms the installation was done to code, so don't skip it even if the contractor doesn't mention it first.
