Nine months of heat, and nights near 7 degrees
Milbank needs a furnace from September through May. That is nine months of the year leaning on it, with winter lows that average 7°F. A furnace here does not get much of a break to rest between seasons.
Grant County has logged 52 winter storms and 46 damaging wind events over the past ten years. Cold like that pushes a furnace to run long stretches at a time. Any new furnace installed has to meet the federal minimum of 80.0 percent AFUE, so it turns most of the fuel it burns into heat for the house instead of losing it up the flue.

In South Dakota, HVAC licensing for homes is left to the cities and towns.
South Dakota leaves HVAC licensing to individual cities and towns, so whether a license is required for this job depends on the city or township the house sits in. There is no statewide license, no state test, and no state record of who did the work. Whatever protection applies here comes from the local government, not from the state.
A furnace installation still needs a permit from the local building office in most cities and counties, along with an inspection once the work is done. That inspection is what checks the gas connection and venting, the part of the job that can hurt someone if it is wrong. It is not a license and it does not test the installer ahead of time, but it is the record that the work was checked.

- What size furnace does my house need?
- It depends on your home's square footage, how it's insulated, its windows, and its layout, so there's no single number that fits every house. A contractor will walk through and run a load calculation, which looks at all of that together rather than just floor space. Going by square footage alone can leave you with a furnace that's too big or too small, and either way it won't heat evenly or hold up as well over time. With winter lows here averaging 7°F, getting this number right matters more than it would somewhere milder.
- How do I know it's time to replace my furnace?
- If your furnace is struggling to keep up, cycling on and off more than it used to, or needing repairs every winter, it's telling you something. An older furnace can still run while having lost much of its efficiency, so age is worth asking about even if it hasn't broken down. Since homes here need heat from September through May, nine months of the year, a furnace on its way out won't get much of a break to recover between seasons. If you're noticing uneven heat room to room, rising bills without a clear reason, or a furnace that just runs longer to do the same job, have it looked at before the next cold stretch.
- Is a high-efficiency furnace worth it?
- For a home here, it's worth serious consideration. Furnaces built since November 2015 have to hit at least 80 percent AFUE, but high-efficiency models go well beyond that, and with nine months of heating season and winter nights averaging 7°F, that difference gets used a lot here, not just on the coldest days. A contractor can walk you through what each efficiency level would mean for your specific house before you decide.
