A short cooling season, with hail to plan around
Milbank only asks a new air conditioner to work June through August, three months a year. Summer afternoons average 80°F, so the job is less about extreme heat and more about sizing the unit right for your house, so it keeps up on the hot afternoons without running harder than it needs to the rest of the season.
Grant County has logged 28 hail events over the past ten years, with hail up to 2.75 inches, plus 46 damaging wind events in that same stretch. 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 a federal minimum of 13.4 SEER2.

In South Dakota, HVAC licensing for homes is left to the cities and towns.
South Dakota has no state HVAC license. That decision is left to cities and towns, so whether a contractor needs one here depends on which town the house is in, and nothing at the state level fills that gap.
What does apply to this job is the permit. Installing an air conditioner in most cities and counties means pulling a permit from the local building office and having the work inspected once it is done. That inspection checks the installation itself, not a license held by the person doing it.

- What size air conditioner does my house need?
- There is no single answer without measuring your house. A contractor works this out from your square footage, how many windows you have, which way they face, how much insulation is in the attic and walls, and the layout of your ductwork. Bigger is not better here. An oversized unit cools the air fast then shuts off before it pulls the moisture out, so the house feels clammy even at the right temperature. A contractor will do this sizing before quoting the job.
- Should I replace the whole system or just the outdoor unit?
- In most cases you want to replace both the outdoor unit and the indoor coil together. They are matched to work at a specific capacity, and pairing a new outdoor unit with an old coil usually means you lose the efficiency you're paying for, sometimes the two won't run right together at all. Age matters too. If the indoor coil is old enough that one part is failing, the other is not far behind it. A contractor can look at the coil's condition and tell you whether it's worth keeping.
- Do HVAC contractors in Milbank need a state license to work on my home?
- South Dakota has no state HVAC license, so it comes down to what Milbank requires locally. What's consistent almost everywhere is the permit. Installing a new air conditioner in most cities and counties means pulling a permit from the local building office, and the work gets inspected once it's done. Ask your contractor whether they're handling the permit and inspection as part of the job.
