Nine months of heat, down to 1 degree
Cavalier needs a furnace from September through May. That is nine months of the year, and on winter nights the average low is 1°F. A furnace here does not get much of a break to rest and cool down between cycles.
A new furnace has to be sized and installed for that kind of cold, not just for a mild fall evening. Any non-weatherized gas furnace built since November 2015 has to reach at least 80.0 percent AFUE, so that floor is already set. What matters after that is whether the unit and the installation match what a 1°F night actually asks of it.

North Dakota requires HVAC contractors to hold a state license.
North Dakota licenses HVAC contractors through the Secretary of State, and that license covers the contractor, not each job. Work under $4,000 does not need a licensed contractor at all. That is the cutoff the state sets, not a judgment about the work itself.
A furnace installation runs well past that $4,000 mark, so the contractor doing this job needs the state license. Most cities and counties in North Dakota also require a permit before a furnace goes in and an inspection when the work is done.

- What size furnace does my house need?
- The right size depends on your square footage, your insulation, your windows, and your home's layout, so there's no single number that fits every house. A contractor works this out with a load calculation that looks at all of that together, not just the size of the room the old furnace sat in. With winter lows here averaging 1°F, getting this right matters more than it would somewhere milder. Too small and it runs constantly without keeping up. Too large and it cycles on and off more than it should, which wears on the parts faster and leaves rooms uneven.
- How do I know it's time to replace my furnace?
- Age and behavior together tell you more than either one alone. Furnaces built to today's 80 percent AFUE minimum still have to work hard through a winter like this one, and older units can fall well below that standard. If yours is cycling more, running longer to reach the same temperature, or needing a repair every season, that's a furnace telling you it's near the end. Homes here need heat nine months of the year, September through May, so a furnace that struggles in the shoulder months usually won't make it through a full stretch at 1°F. If a repair is going to cost close to what a new unit would, replacement is the better use of that money.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what you're paying for gas now, since a higher AFUE rating means less fuel burned for the same heat. With nine months of heating a year here, that difference adds up more than it would somewhere that only runs a furnace for a few months. High-efficiency furnaces also vent differently, through PVC pipe instead of a metal flue, which can affect how the installation goes depending on your home's setup. A contractor can walk through the actual models and what each one would mean for your house.
