Eight months of heat in Parkston winters
Your furnace has to cover October through May here, eight months of the year. Winter nights average 12°F, so on the coldest stretches it runs most of the day just to hold the house steady.
That long a season and that kind of cold put real hours on a furnace, year after year. Any new furnace installed now has to meet the federal minimum of 80.0 percent AFUE, and sizing it right for a Parkston winter is what decides whether it keeps up when the temperature drops and stays down.

In South Dakota, HVAC licensing for homes is left to the cities and towns.
Hutchinson County has no state license behind it, and South Dakota leaves that decision to each city or town instead. Some places set their own rules for who can install a furnace within their limits. Others have none, which means there is no record anywhere of who is qualified to do the work.
What applies here is the permit. In most cities and counties, putting in a new furnace calls for a permit from the local building office, and an inspector checks the completed work before it is signed off. That inspection is where a bad gas connection gets caught, since that is the part of the job that can hurt someone. It does not test the installer ahead of time, but it is the one check on this job likely to exist here no matter what the town requires of contractors.

- What size furnace does my house need?
- The right size comes from a load calculation, not a guess based on square footage. A contractor measures your walls, windows, insulation, and ceiling height, then factors in local winter lows to figure out how much heat your house actually loses on a cold night. With average lows around 12°F here, that calculation matters more than it would somewhere milder. A furnace that's too big will short cycle and wear out faster, and one that's too small will run constantly and still leave rooms cold. Have a contractor size it for your specific house before you buy anything.
- How do I know it's time to replace my furnace?
- Watch for a few signs together, not just one. If your furnace needs repair more than once a season, if your heating bills keep climbing even though the house hasn't changed, or if some rooms stay cold no matter what you do, the furnace is telling you something. Homes here run their heat eight months out of the year, October through May, which puts more hours on the equipment than in most places, so an older furnace here has worked harder than the same age furnace somewhere milder. If yours is starting to act up, have a contractor look at it before it fails on one of the 12°F nights instead of after.
- Is a high-efficiency furnace worth it?
- It depends on how much you heat and what you're comparing it to. Every new non-weatherized gas furnace has to hit at least 80.0 percent AFUE, so that's your floor no matter what you buy. High-efficiency models go well beyond that, and because homes here need heat eight months a year, the furnace runs longer and more often than in a climate with a short winter. That extra runtime is exactly the condition where a more efficient furnace has the most time to make a difference. A contractor can walk you through the models available and what fits your house and your budget.
