Nine months of heat, six degrees on a winter night
A furnace in Mandan works from September through May. That is nine months of the year with the burner cycling on and off to keep a house warm. Winter nights here average 6 degrees, and a furnace has to recover fast from that kind of cold, night after night.
Most homes here heat with gas, and any new gas furnace sold today has to reach at least 80 percent AFUE. That is the federal minimum, not a special feature. Power matters too. Some households in North Dakota lose power for a full day or more in a bad storm, and this area has logged 29 winter storms and 114 damaging wind events over the past ten years. A furnace that starts back up on its own when the power returns is worth asking about when you are choosing a new one.

North Dakota requires HVAC contractors to hold a state license.
The state tested this contractor and keeps a record of the license, and that record follows the business, not the specific job. Work under $4,000 falls outside the licensing requirement, so a small repair can be done without a licensed contractor. A furnace installation runs well above that line, so the contractor doing this job holds a state license.
Because a furnace burns gas, the connection to the gas line is the part that matters most, and in most cities and counties in North Dakota that work needs a permit from the local building office along with an inspection once the job is done. That inspection is separate from the state license. Most homes in Morton County heat with gas, which is exactly the kind of installation a building inspector checks before signing off.

- What size furnace does my house need?
- It depends on your home's square footage, insulation, window count, and layout, so there is no single number that fits every house. A contractor sizes a furnace by running a load calculation on your specific home rather than going by square footage alone. Too big and the furnace short cycles, wearing out parts faster. Too small and it will run constantly through the cold months here and still struggle to keep up on the coldest nights.
- How do I know it's time to replace my furnace?
- Watch for rooms that won't heat evenly, a furnace that cycles on and off more than it used to, or a gas bill that jumps with no other explanation. If a repair keeps coming up, or a contractor tells you the heat exchanger is cracked, that's a safety issue and reason enough to replace it rather than fix it again. Homes here need heat from September through May, so a furnace that's struggling has to work hard most of the year.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what furnace you have now. Any non-weatherized gas furnace made on or after November 19, 2015 has to reach at least 80 percent AFUE, so even a standard model today isn't wasteful the way older units were. A high-efficiency furnace burns less gas to make the same heat, which matters here since homes need heat nine months out of the year. A contractor can walk through the difference for your home, since high-efficiency models need a different venting setup than standard ones.
