Nine months of heat, winter nights near 8 degrees
Brookings needs a working furnace September through May. That is nine months of the year, and on winter nights that average 8°F, a furnace that struggles is a furnace that fails you when you need it most.
The county has logged 34 winter storms and 77 damaging wind events over the past ten years. A new furnace has to hold up through that, not just run on a mild fall evening. A non-weatherized gas furnace built on or after November 19, 2015 has to reach at least 80.0 percent AFUE. With 44.9 percent of homes here heating with gas, that minimum applies to a lot of your neighbors too.

In South Dakota, HVAC licensing for homes is left to the cities and towns.
South Dakota leaves this to the cities and towns, which means there is no state record of who is licensed to install your furnace. Whether a contractor needs a local license at all, and what that license requires, depends on the city or township the house sits in. That is different from a state license, where one board tests contractors and keeps a record that follows them anywhere in the state.
What stands in for that here is the permit process. In most cities and counties, installing a furnace needs a permit from the local building office, and the work gets inspected once it is done. That inspection is what stands between you and a bad hookup on this job. In Brookings County, 44.9% of homes heat with gas, so that inspection is checking work that matters to a lot of houses here, not just yours.

- What size furnace does my house need?
- The right size depends on your home's square footage, insulation, window count, and layout, so there is no single number that works for every house. A furnace that is too big cycles on and off too fast and never runs long enough to heat evenly. One that is too small runs constantly and still can't keep up on a night at 8 degrees. A contractor sizes it with a load calculation on your actual house, not a guess based on square footage alone.
- How do I know it's time to replace my furnace?
- Watch for rooms that stay cold no matter how high you turn the heat, a furnace that cycles on and off more than it used to, or repair calls that keep coming back. Age matters too. Furnaces here run from September through May, nine months a year, so a unit gets more hours on it each season than in most places. If yours is old enough that parts are getting hard to find, or the repair bill starts to rival what a new furnace would run, replacement is worth considering over the next fix.
- Is a high-efficiency furnace worth it?
- It depends on how many months your furnace runs and how you plan to stay in the house. Homes here need heat nine months out of the year, from September through May, so a furnace gets far more use than it would somewhere with a short winter. Any non-weatherized gas furnace built after November 2015 has to hit at least 80 percent AFUE by law, so even the baseline units aren't inefficient. Going higher than that costs more upfront, and whether it pays off depends on your specific furnace and usage, which a contractor can walk through with you.
