Three months of real heat, and hail to plan around
Summers here run June through August, with afternoons averaging 80°F. That is a short season, but it still asks a new air conditioner to work through the hottest stretch of the year without a break, so the unit you put in needs to be sized right for your house, not just swapped in to match the old one.
Roberts County has seen 21 hail events and 115 damaging wind events over the past ten years, with hail up to 2.5 inches. The outdoor unit sits exposed to that, so where it goes and how it is protected matters as much as the equipment itself. Any new central air conditioner installed today also has to meet the federal efficiency minimum of 13.4 SEER2.

In South Dakota, HVAC licensing for homes is left to the cities and towns.
South Dakota leaves HVAC licensing to cities and towns, so whether a license applies here depends on whether Roberts County or the town it sits in has its own requirement on the books. Where no such local rule exists, there is no license and no record of testing behind whoever installs this air conditioner.
In most cities and counties, installing an air conditioner calls for a permit from the local building office, along with an inspection once the work is finished. That inspection is what checks the work was done right, since no license is standing in to do it.

- What size air conditioner does my house need?
- A contractor has to work this out with a load calculation, not a chart based on square footage. That calculation looks at how much sun your walls and windows get, how much insulation is in the attic, and how much air leaks in and out. An oversized unit cools the air fast but shuts off before it pulls the moisture out, so the house feels clammy. Undersized, and it runs constantly on the hottest afternoons and still can't keep up. There's no shortcut that gets this right for your specific house.
- Should I replace the whole system or just the outdoor unit?
- If the indoor coil and outdoor unit are different ages or different efficiency ratings, replacing just the outdoor unit often causes problems. The two are matched at the factory to work together, and pairing an old coil with a new condenser can mean the system never reaches the efficiency it's rated for. A contractor can check whether your indoor coil will work with a new outdoor unit or whether both need to come out together. If the indoor coil is old enough that it's close to failing on its own, replacing only the outdoor unit just delays a second job.
- Do HVAC contractors in Sisseton need a state license to work on my home?
- South Dakota has no state HVAC license, so this depends on whether Sisseton itself licenses contractors, not on a state rule. What does apply almost everywhere is a permit. Installing a new air conditioner in most cities and counties requires a permit from the local building office and an inspection once the work is finished. Ask the contractor directly whether they're licensed with the city and whether they'll pull the permit for the job.
