Eight months of heat, and nights near 13 degrees
A new furnace here has to work most of the year. Homes in Yankton County need heat from October through May, and winter nights average 13°F. That is not a mild draw on the system a few weeks a year. It is eight months of steady demand.
More than half the homes here heat with gas, and any non-weatherized gas furnace built since November 2015 has to reach at least 80 percent AFUE by law. That is the floor, not a feature. The county has also logged 35 winter storms and 62 damaging wind events over the past ten years, so a furnace here should be installed to keep running through the kind of weather that knocks out power and piles up snow against the vents.

In South Dakota, HVAC licensing for homes is left to the cities and towns.
Yankton County does not run its own contractor license either, so whether the crew installing your furnace is licensed depends on whether the city they're working in requires one. Some towns in South Dakota do, some leave it to the county, and some have no rule at all. Nothing at the state level tracks who these contractors are or checks that they passed a test.
With no state license behind the work, the permit is what stands in for it. Most cities and counties require a permit before a furnace gets replaced, and an inspection once it's in. That inspection is where someone checks the gas connection, since a loose fitting or bad joint there is the part of this job that can hurt someone. More than half the homes in Yankton County heat with gas, so that connection is worth getting checked, permit or not.

- What size furnace does my house need?
- The right size depends on your square footage, how well your house is insulated, your ceiling height, your windows, and the layout of your ductwork. There's no shortcut for this. A contractor works out the number using a load calculation that looks at your house specifically, not a rule of thumb based on square footage alone. Putting in a furnace too big for the house wastes fuel and wears out faster from turning on and off too often. Too small, and it will run constantly through the coldest months and still not keep up. With winter lows here averaging 13°F, getting this right matters more than in a milder climate.
- How do I know it's time to replace my furnace?
- If your furnace is struggling to keep up on the coldest nights, cycling on and off more than it used to, or needing repairs every year, it's time to start planning a replacement rather than waiting for it to fail outright. Homes here need heat from October through May, eight months of the year, so a furnace that quits partway through that stretch is a real problem, not an inconvenience. Rising gas bills without a clear reason, uneven heat between rooms, and an aging furnace are all signs worth taking seriously. Waiting until it fails means choosing a furnace in a hurry instead of on your own timeline.
- Is a high-efficiency furnace worth it?
- Every non-weatherized gas furnace sold today has to reach at least 80 percent AFUE, so the real question is whether it's worth paying more for a higher-efficiency model above that baseline. With heat needed here from October through May and winter nights averaging 13°F, a furnace runs a lot more here than in a warmer climate, which is exactly the situation where higher efficiency pays off over the life of the unit. More than half of homes in the county heat with gas, so this is a common decision here. A contractor can walk through the actual models and price difference for your house.
