Three months of heat, then hail and wind the rest of the year
Your AC in Madison only has June through August to earn its keep, with afternoons averaging 80°F. That is a short, hard push. The unit sits idle most of the year, then gets asked to run for weeks straight, and a system that has been sitting can show its weak points fast once it starts working.
The outdoor unit takes the other hit. Lake County has logged 35 hail events and 48 damaging wind events over the past ten years, with hail up to 2 inches. Hail bends the thin aluminum fins on the outdoor coil, and wind drives debris into the cabinet. Either one can cut off the airflow the unit needs, and you notice it as warm air inside or a system that runs but never quite cools the house.

A new air conditioner would save little on running costs in Lake County, so the repair decision comes down to the unit's condition.
Estimates for a typical Lake 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.
South Dakota does not test or license HVAC contractors at the state level. Whatever rule applies to a contractor working on your air conditioner comes from the city or town, not the state, so there is no state record behind the work and no statewide standard it was measured against.
What does apply no matter where the house sits is federal law on refrigerant. Your air conditioner has a sealed refrigerant circuit, and any technician who opens it to repair or recharge it must hold EPA Section 608 certification. That certification is federal, not a local credential, and it is the one check on this repair that holds everywhere in South Dakota.

- Why is my AC not blowing cold air?
- Most of the time it is a dirty filter or a low refrigerant charge. A clogged filter blocks airflow across the coil until the coil ices up, and once that happens you get warm air or none at all. Low refrigerant almost always means a leak somewhere in the line, and that's not something to keep topping off since it takes a licensed technician to find and seal it. If the filter looks clean, the next step is having someone check the charge and the coil.
- Why is my AC leaking water?
- Water around your unit usually means the condensate drain line is clogged. Your AC pulls moisture out of the air as it cools, and that water is supposed to run out through the drain line to the outside. When the line clogs with algae or debris, the water backs up and drips into the house instead, often near the indoor unit. A frozen coil that's now thawing can cause the same thing, so it's worth checking whether the system was running warm before the leak showed up.
- Why won't my AC turn on?
- Start with the thermostat and the breaker before anything else. Check that the thermostat is set below room temperature and has working batteries, then check the breaker panel for a tripped switch. If both look fine, the problem is likely in the unit itself, and with summer afternoons here averaging 80°F, a system that won't start can mean a rough few days waiting on repair, so it's worth calling someone in fairly quickly. Whoever comes out to look at it needs an EPA Section 608 certification if the fix involves opening the refrigerant side, which is federal law everywhere.
