Three months of cooling, a lot of weather in between
Your air conditioner only has to cool the house from June through August here, with afternoons averaging 80°F. That is not a long season, but the condenser outside still sits through everything Roberts County weather brings the rest of the year.
Roberts County has seen 21 hail events over the past ten years, with hailstones as large as 2.5 inches. A stone that size can bend the thin aluminum fins on your condenser coil. Bent fins block airflow, and less airflow means less cooling. The same stretch brought 115 damaging wind events, which can drive debris into that coil or knock the unit around on its pad. When summer comes and you finally turn the system on, that damage shows up as a house that takes longer to cool or air that never gets quite as cold as it should.

A new air conditioner would save little on running costs in Roberts County, so the repair decision comes down to the unit's condition.
Estimates for a typical Roberts 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.
Roberts County does not run its own HVAC licensing program, and South Dakota leaves that decision to each city and town. Whether a contractor needs a local license depends on the town they are working in, not on any state list. There is no state board keeping a record of who is qualified to repair an air conditioner here.
What does apply in Roberts County is federal law. Anyone who opens the refrigerant lines on your air conditioner has to hold EPA Section 608 certification. That is not optional and it is not local. It covers the part of an AC repair that involves handling refrigerant, which is the part with real risk if it is done wrong.

- Why is my AC not blowing cold air?
- The most common cause is low refrigerant from a leak, a dirty coil that cannot pull heat out of the air, or a failing compressor. A dirty air filter can also choke off airflow enough that what comes out feels warm. Refrigerant work requires an EPA Section 608 certified technician by federal law, so this isn't something to open up yourself. A contractor can check pressures and airflow and tell you which of these it is.
- Why is my AC leaking water?
- Usually the condensate drain line is clogged, so water backs up instead of draining outside. It can also mean the coil is frozen over, and water shows up as it melts. A dirty filter is a common reason the coil ices up, since it restricts airflow across it. If the drain pan itself has rusted through, that's a repair a contractor needs to look at directly.
- Why won't my AC turn on?
- Start with the thermostat batteries and the breaker before assuming the worst. If those are fine, a tripped safety switch, a bad capacitor, or a wiring issue at the outdoor unit are common culprits. With 115 damaging wind events recorded here over the past ten years, it's also worth checking that nothing knocked loose or damaged the outdoor unit or its power connection. A contractor can test the electrical components to find out which part failed.
