Nine months of heat, down to 5 degrees
Your furnace in Wahpeton runs September through May, nine months of the year. On winter nights it is holding the house against a 5°F average low. There is not much of a real off season here, only the stretch when the burner runs less.
A new gas furnace installed today has to reach 80 percent AFUE at minimum, the federal floor for non-weatherized units built since November 2015. Winter storms have hit Richland County 60 times over the last ten years, with 82 damaging wind events in that same stretch. When the power goes out, a furnace that starts back up on its own matters, and in North Dakota, 7 percent of households went at least a day without power in 2024.

North Dakota requires HVAC contractors to hold a state license.
The state tested this contractor and keeps a record of them with the Secretary of State, and that record covers the contractor rather than any single job. Work under $4,000 falls outside that rule, so on smaller jobs the license requirement does not apply, though a full furnace installation runs well past that line.
Because this job is a licensed one, the license is what stands behind the work here. It does not replace the permit that most building offices require for a furnace swap, along with an inspection once the job is finished.

- What size furnace does my house need?
- A contractor works this out with a load calculation, not a formula based on square footage alone. That calculation looks at your walls, windows, insulation and how the house is laid out, because two homes the same size can need different sized furnaces. With winter lows here averaging 5°F, getting this right matters more than in a milder climate. Too big and the furnace short cycles, too small and it runs constantly without keeping up on the coldest nights.
- How do I know it's time to replace my furnace?
- The clearest sign is a furnace that can't keep the house warm through a full winter anymore, since homes here need heat nine months of the year, from September through May. Rising repair calls are another sign, especially if the same part keeps failing. An older furnace running on standing pilot or one that predates 2015 is also worth replacing, since furnaces made after November 19, 2015 have to reach at least 80 percent AFUE. If yours is well below that, a new furnace will use less fuel to heat the same house.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what you're paying now to heat it, and a contractor can walk through those numbers for your specific furnace. What's true everywhere is that a high-efficiency furnace burns less fuel to produce the same heat, and in a place where the furnace runs nine months a year, that adds up more than it would somewhere milder. The tradeoff is a higher upfront cost. A contractor can price out both options for your house and let you compare.
