Three months of heat, and hail in between
Your air conditioner in Minnehaha County only works three months a year, June through August, with afternoons averaging 81°F. That is a short season, but the machinery outside faces a different threat the rest of the year.
Minnehaha County has seen 95 hail events and 144 damaging wind events over the past ten years, with hailstones as large as 3.5 inches. Hail bends the thin aluminum fins on the outdoor coil and can crack the fan blade or housing. A coil with flattened fins cannot move heat the way it should, so the house does not cool down even though the unit is running.

A new air conditioner would save little on running costs in Minnehaha County, so the repair decision comes down to the unit's condition.
Estimates for a typical Minnehaha County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, South Dakota fuel prices and NOAA climate normals. Your home will differ.
Repair makes sense when a part like a capacitor or contactor has failed.
Replacement makes sense when the compressor has failed or the system uses R-22 refrigerant, which is no longer made.
In South Dakota, HVAC licensing for homes is left to the cities and towns.
In Minnehaha County, whether a contractor needs a local license depends on the city. South Dakota does not test or license HVAC contractors at the state level, so there is no statewide record to check. Sioux Falls and the smaller towns around it set their own rules, and what applies to your repair comes down to the address the work is done at.
For an air conditioner repair, the part that matters most is the refrigerant. Any technician who opens the refrigerant side of your system, no matter where you live, has to hold EPA Section 608 certification. That is a federal requirement, not a local license, and it exists because refrigerant work is the part of the job that can go wrong in ways a homeowner cannot see. Whether anyone local inspects the repair itself depends on the city's own rule.

- Why is my AC not blowing cold air?
- The most common reason is low refrigerant from a leak somewhere in the line set or coil. It can also mean the compressor has failed, or the coil is frozen over and just needs time to thaw before it can work right. A dirty filter can choke airflow enough to cause the same complaint, so check that first since it costs nothing to look. Anyone who opens the refrigerant side to check the charge has to hold EPA 608 certification, so this part of the repair goes to a licensed contractor.
- Why is my AC leaking water?
- Water around your unit usually means the condensate drain line is clogged and backing up instead of draining outside. It can also mean the coil froze and is now melting and overflowing the drain pan. A cracked drain pan or a line that was never sloped right will do it too. Shut the system off until it is looked at, since standing water near the furnace or air handler can damage more than the AC.
- Why won't my AC turn on?
- Start with the thermostat. Dead batteries or a setting bumped too high will stop the system cold with no other symptom. If the thermostat looks fine, check the breaker, since a tripped one is common after a storm and this area sees plenty of those, with 144 damaging wind events recorded here over the past ten years. If the breaker is fine and the system still won't start, the capacitor or the contactor has likely failed and needs a contractor to replace it.
