Nine months of heat in Bemidji winters
Furnaces here run September through May, nine months of the year. Winter nights average 0°F through December through February, and a new furnace has to carry that load every night for the full season, not just get through a cold snap.
Beltrami County has recorded 67 winter storms and 99 damaging wind events over the past ten years, the kind of weather that can knock out power along with the heat. Any furnace installed today has to meet the federal minimum of 80 percent AFUE. Meeting that number is the starting point. Whether the unit and the installation behind it hold up to nine straight months of hard use is what matters after that.

Minnesota has no state license for HVAC contractors.
Minnesota does not put HVAC contractors through a state licensing exam, and it does not keep a state registry of them either. There is no state credential to check because the state issues none. Anyone can put a furnace install on their list of work.
What stands in for that here is the local permit process. In most cities and counties, a new furnace needs a permit from the local building office, and an inspector checks the completed work once it is done. That permit and inspection are the record this job leaves behind, not a license.

- What size furnace does my house need?
- That comes from a heat loss calculation, not the square footage of your house. A contractor works out how fast your house loses heat on a cold night, using your walls, windows, insulation and layout, and sizes the furnace to match. This matters more here than in a lot of places, since winter nights average 0°F and the furnace has to keep up with that. A furnace that is too big cycles on and off and wears out faster. One that is too small runs constantly and still can't keep the house warm on the coldest nights. Ask for the calculation, not a guess based on your old furnace or your neighbor's house.
- How do I know it's time to replace my furnace?
- Watch for uneven heat, rooms that won't warm up, a furnace that runs longer than it used to, or repair calls that keep coming back. Age matters too. Furnaces here work hard, since homes need heat from September through May, nine months of the year, and that adds up over the furnace's life. If yours is old enough that parts are getting harder to find, or a contractor tells you the next repair costs about as much as replacing it, that's the point to stop patching it. A cracked heat exchanger or a furnace that trips its limit switch repeatedly is not something to wait on.
- Is a high-efficiency furnace worth it?
- Every new non-weatherized gas furnace has to hit at least 80 percent AFUE, so the real question is whether to go higher than that baseline. A furnace built above that minimum burns less gas to make the same heat, and with nine months a year of heating in this area, that adds up over a season. The tradeoff is the venting is different, since these furnaces vent through PVC pipe instead of a metal flue, which can change what the installation involves. A contractor can walk you through what fits your house, since the efficiency level that makes sense depends on the specific job.
