Three months of heat, a unit that takes ten years of weather

Summers in Wagner run June through August, with afternoons averaging 85 degrees. That is the stretch your air conditioner has to carry the house.

The rest of the year, the outdoor unit still sits there taking whatever the weather brings. Charles Mix County has logged 80 hail events and 89 damaging wind events over the past ten years, with hail as large as 2.5 inches. A new central air conditioner needs to handle that exposure, and it also has to meet the federal minimum of 13.4 SEER2 that applies to any system installed now.

In South Dakota, HVAC licensing for homes is left to the cities and towns.

Charles Mix County has no state license behind this job, since South Dakota leaves HVAC licensing to individual cities and towns. Whether a rule applies here depends on the address, not on a statewide standard, and there is no state record of who is qualified to do this work.

What covers this installation is the permit. Replacing an air conditioner in most South Dakota cities and counties requires a permit from the local building office, along with an inspection once the work is done. That inspection is what checks the job, not a license. It is the building office standing in for the credential the state does not issue.

What size air conditioner does my house need?
There's no single size that fits every house, and picking one by square footage alone gets it wrong more often than not. A contractor works this out with a load calculation, which looks at how much heat your house actually gains, including your insulation, your windows, and how much shade the house gets. An oversized unit cools the air fast but shuts off before it pulls the moisture out, so the house feels clammy. Get the load calculation done rather than matching the old unit's size or guessing from the tonnage next door.
Should I replace the whole system or just the outdoor unit?
In most cases, replace both at once. The outdoor unit and the indoor coil are matched to work together, and pairing a new outdoor unit with an old coil usually means it never reaches the efficiency it's rated for. If your indoor coil is old enough that the outdoor unit needs replacing, it's likely near the end of its own life too. A contractor can check the coil's condition and tell you whether it's worth keeping.
Do HVAC contractors in Wagner need a state license to work on my home?
South Dakota doesn't issue a state HVAC license. Licensing is handled by individual cities and towns, so whether a contractor needs one depends on where your house sits. What does apply almost everywhere is a permit. Installing a new air conditioner typically requires a permit from the local building office, along with an inspection once the work is finished.
