Three months of real heat, then done
Summer here runs June through August, with afternoons averaging 85°F. That is the stretch a new air conditioner has to handle, and it needs to do it without strain since it is not built to run hard year round.
Fall River County also sees its share of hail and wind, 116 hail events and 154 damaging wind events over the last ten years, with hailstones up to 4 inches recorded. The outdoor unit sits exposed to that, so the cabinet and coil fins matter. Any new central air conditioner installed today also has to meet the federal minimum of 13.4 SEER2, so that efficiency level is the starting point, not an upgrade.

In South Dakota, HVAC licensing for homes is left to the cities and towns.
South Dakota has no state HVAC license. The state leaves that decision to cities and towns, so whether a contractor needs a local license depends on exactly where the house sits in Fall River County. That means there is no state record to check for a contractor working here. Whatever oversight exists comes from whatever the local town or the county itself has set up, not from Pierre.
For this job, the installation should still go through the local building office. In most places, replacing an air conditioner needs a permit and a final inspection once the work is done. That inspection is what confirms the unit was installed correctly, since there is no state license standing behind the work here.

- What size air conditioner does my house need?
- The right size comes from a load calculation, not a chart based on square footage. A contractor measures your windows, insulation, ceiling height and duct layout, then works out how much heat your house gains on a hot afternoon. An oversized unit cools fast but shuts off before it pulls the humidity out of the air, and an undersized one runs constantly and still can't keep up on the hottest days. Ask whoever quotes the job to walk you through the calculation, not just quote a tonnage.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit weren't installed together, replacing only the outdoor unit usually causes problems. The two are matched for refrigerant charge and airflow, and pairing a new condenser with an old coil can mean poor cooling and a shorter life for the new equipment. A contractor can check the age and condition of the coil, the ductwork and the refrigerant lines before telling you whether a full swap makes sense. New units also have to meet the 13.4 SEER2 minimum that's applied since 2023, so a mismatch can keep your system from reaching the efficiency it's rated for.
- Do HVAC contractors in Hot Springs need a state license to work on my home?
- South Dakota doesn't issue a state HVAC license, so the rule depends on the city or county. Some cities require their own license or permit for work like this, others don't. Most places do require a permit and inspection when you install a new air conditioner, so ask the local building office what applies in Hot Springs before the work starts.
