HVAC in South Dakota has to fight wind that pulls heat out of the windward rooms and dust into the returns. The burner can be fine while the north bedrooms never catch up, because the wall is a sieve. That is not the same call as a furnace that will not light. Say which one you have. A house on an open lot east of the river and a house on the west river both feel this, and the dust is worse where the ground is bare.
Look at the intake and exhaust on high-efficiency equipment. A gust stacking on one wall changes the draft and can ice a termination or pull the condensate into a problem. Filters load up after a long blow, especially when a shelterbelt is thin and the yard is open. Ask what was ruled out before parts are named. A buried return and a filter pasted shut can imitate a failed blower. Do not skip the outdoor unit if cooling has gone weak after a debris-filled wind.
Heating still matters on this prairie, but the local fact is infiltration, not a generic cold lecture. Rooms over a garage, ducts in a windy attic, and a flue that misbehaves when the gust is on that side of the house are the usual plot. If you smell trouble at the burner or the heat exchanger is in question, stop using the equipment until it is seen. Comfort in a guest room can wait. Combustion cannot.
If the system is being replaced, ask whether the load was figured for this exposed house or copied from the old nameplate. Wind on a bare lot is part of the load. Ducts that leak into an attic give the new equipment away. Efficiency labels compare a test. They are not a promise about your house. Matched indoor and outdoor pieces are a different scope from a new box hung on an old coil.
Say heat or cooling, dead or merely weak on the windward side, and the town. Mention dust, a whistling return, or a termination that ices. If the house is uncomfortable right now, say that first. The wind will not pause while the filter is discussed. Call the number on this page.
