Mitchell asks a lot of a furnace
Winter nights here average 11°F, and homes need heat from October through May. That is eight months of the year your furnace has to work, not just a few cold snaps.
Any gas furnace installed new has to reach at least 80 percent AFUE. That is the federal minimum now, so it is the floor for what goes into your house, not an upgrade you have to ask for.

A high-efficiency gas furnace would save about $80 a year to run in Davison County compared with a gas furnace.

In South Dakota, HVAC licensing for homes is left to the cities and towns.
Davison County itself does not run a contractor license, so whether the person in your basement is licensed comes down to whether their city or town requires one. Some do, some don't, and the state leaves that choice to them entirely. There is no statewide test or record to check either way.
What you can count on for a furnace installation is the permit process most local building offices use for this kind of job. That means someone applies for a permit, and an inspector checks the work once it's done, including the gas connection, which is the part that matters most if it's done wrong. That inspection is not a license and does not tell you anything about the installer's track record. It only confirms that this particular job met code when it was finished.

- What size furnace does my house need?
- The right size depends on your square footage, your insulation, your windows and how the ductwork is laid out, so there is no number that fits every house. A contractor works this out with a load calculation, not a chart based on home size alone. With winter lows here averaging 11°F, getting this right matters more than it would somewhere milder. Too big and the furnace short cycles instead of heating evenly. Too small and it runs constantly through the coldest months without keeping up. Have a contractor measure your house rather than guessing from the size of your old unit.
- How do I know it's time to replace my furnace?
- Watch for uneven heat between rooms, a furnace that cycles on and off more than it used to, or a rise in gas use without a reason. Age matters too. Furnaces here run from October through May, eight months a year, so the wear adds up faster than in places with a short winter. If yours needs repairs more than once a season, or if a repair call turns up a cracked heat exchanger, replacement is the safer route. A contractor can tell you whether what you're seeing is normal wear or the start of a real problem.
- Is a high-efficiency furnace worth it?
- It depends on how much you heat and what you're replacing. Every non-weatherized gas furnace sold new today has to reach at least 80 percent AFUE, so even a standard model wastes less fuel than an older one. A high-efficiency furnace goes beyond that minimum and burns less gas to produce the same heat, and with eight months of heating season here that difference shows up on more bills than it would somewhere warmer. Whether the higher upfront cost makes sense for your house is worth asking a contractor directly, since they can weigh it against your current furnace and your gas use.
