Three months of real heat, and hail to plan around
Summer here runs June through August, and afternoons average 83°F. That is not a long season, but it is a demanding one, and a new air conditioner needs to be sized to handle those afternoons without struggling.
Union County has also seen 63 damaging wind events and 23 hail events over the past ten years, with hail up to 1.75 inches. The outdoor unit sits outside through all of that, so where it goes and how it is installed matters. Any new central air conditioner installed today has to meet the federal efficiency minimum of 13.4 SEER2.

A higher-efficiency unit would save about $30 a year to run in Union County compared with a new unit at the federal minimum.

In South Dakota, HVAC licensing for homes is left to the cities and towns.
That leaves it up to Union County or whichever town the house is in, and whether a local license applies here depends on the address, not on anything the state tracks. South Dakota does not test or record HVAC contractors itself.
What covers this job is the permit process. Installing an air conditioner in most cities and counties needs a permit from the local building office, and the work gets inspected once it is done. That inspection is what stands behind the installation here, since no state license does.

- What size air conditioner does my house need?
- There is no single size that fits every house. It depends on your square footage, your windows, your insulation, and how your house holds heat on an 83°F afternoon. A contractor works this out with a load calculation, not a chart based on square feet alone. Putting in a unit that is too big cools the air fast but shuts off before it pulls the humidity down, which leaves the house feeling clammy. Too small and it runs constantly trying to catch up. Have a contractor size it for your house, not the one next door.
- Should I replace the whole system or just the outdoor unit?
- In most cases the outdoor unit and the indoor coil need to be matched, so replacing only the unit outside can leave you with a system that never runs the way it should. If your indoor coil is old, it may not be rated to work with a new outdoor unit at the efficiency it is supposed to deliver. Any new outdoor unit installed now also has to meet the 13.4 SEER2 minimum, and matching that to an aging coil is where problems start. A contractor can look at the coil, the age of both pieces, and tell you whether a full swap makes more sense than a partial one.
- Do HVAC contractors in North Sioux City need a state license to work on my home?
- South Dakota does not issue a state HVAC license. Licensing is left to cities and towns, so whether a contractor needs one depends on where the house is, not on any state rule. Most cities and counties do require a permit from the local building office for an air conditioner installation, along with an inspection once the work is done.
