Eleven months of work a year in Vermillion
Your furnace runs October through May here. Your air conditioner takes over for June through August. That leaves the system resting only one month all year.
Winter nights average 13°F, and at that temperature the burner or heat pump runs long and hard, night after night, for eight straight months. Summer afternoons averaging 83°F push the compressor just as hard the other way, with almost no break between one season and the next. Clay County has also seen 32 winter storms and 40 damaging wind events over the past ten years, and wind that strong can knock loose a vent connection or drive debris into an outdoor unit. When a part is close to failing, this is where it shows. A furnace that will not light on the coldest nights. An air conditioner that cannot keep up once the afternoon heat sets in.

A new furnace and air conditioner would cut about $100 a year off heating and cooling for a typical Clay County home.
Estimates for a typical Clay County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, South Dakota fuel prices and NOAA climate normals. Your home will differ.
Repair makes sense when one part has failed.
Replacement makes sense when the furnace's heat exchanger is cracked, the air conditioner's compressor has failed, or repairs keep coming.
In South Dakota, HVAC licensing for homes is left to the cities and towns.
South Dakota does not license HVAC contractors at the state level. Whether a contractor needs a license to work on your system depends on where in Clay County your house sits, since that decision is left to individual cities and towns rather than the state. There is no state exam behind this and no state record to check either way.
With no state license standing behind the work, whatever protection exists here comes from whatever the city or town where your house sits requires on its own. Gas repair is the part of this job where a mistake matters most, since it involves burning gas and venting it safely. Whether that gets an outside check depends entirely on the local rule where you live, not on any state requirement, because South Dakota has none.

- Why is my heat not working?
- Start with the thermostat. Check that it's set to heat and the temperature is set above the room temperature, since a setting bumped by accident is the simplest explanation. If that's not it, check the breaker and the furnace's own power switch, often a light switch near the unit. A furnace that won't light at all, or lights and then shuts off, points to a problem with the igniter or the flame sensor, and that needs a contractor to look at it. With winter nights here averaging 13°F, a furnace that's out for even a day is worth getting checked right away.
- Why is my system running but not cooling the house?
- Check the air filter first. A filter clogged with dust blocks airflow across the coil, and without enough airflow the coil can ice up and stop cooling the air that passes over it. Check the outdoor unit too. If the fan isn't spinning or the coil is caked with dirt or grass clippings, heat can't leave the house, no matter how hard the system runs. If the filter is clean and the outdoor unit is running clear, the system may be low on refrigerant, and that's a repair for a contractor, since it means there's a leak somewhere in the line.
- What can I check before calling for HVAC repair?
- Check the thermostat settings, the breaker, and the filter. Those three catch a surprising number of no-heat and no-cool calls before they start. For the furnace, look for a light switch nearby that may have been turned off. For the air conditioner, walk outside and see if the fan is spinning and the coil is free of debris. If everything there looks right and the system still isn't heating or cooling, that's the point to call a contractor, since South Dakota leaves HVAC licensing to the city or town, so who's licensed to do the repair depends on where the house is.
