Three months of heat, then storms the rest of the year
Aberdeen only asks a lot of your air conditioner for about three months, June through August, with afternoons averaging 81°F. That's a short season, but the unit still has to run hard through the hottest stretch of the day, and a system that's been sitting idle since last summer is exactly the kind that struggles when you first switch it on.
Brown County has logged 99 hail events and 187 damaging wind events over the last ten years, with hail up to 4 inches. Your condenser sits outside through all of it. Hail bends the thin fins on the coil and blocks airflow, and wind can knock the unit out of level or send debris into the fan. If your AC is running weak or loud, or not cooling like it should, that outdoor unit is worth a look.

A new air conditioner would save little on running costs in Brown County, so the repair decision comes down to the unit's condition.
Estimates for a typical Brown 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.
Whether this repair needs a local license depends on where in Brown County the house sits. South Dakota does not test or record HVAC contractors at the state level, so there is no state license behind the work, only whatever the city or town asks for, and that can mean a real license, or it can mean nothing at all.
What does apply no matter where the house is in Brown County is federal. Repairing an air conditioner means opening the refrigerant side of the system, and anyone who does that has to hold EPA Section 608 certification. That is not a local credential and it does not depend on the address. It is the one requirement that follows the refrigerant itself, the same in Aberdeen as anywhere else.

- Why is my AC not blowing cold air?
- The most common reason is a dirty air filter choking off airflow across the coil, which can make the coil ice up and send warm air through the vents. Low refrigerant from a leak is another common cause, and that's a repair only a tech with EPA Section 608 certification can legally handle, since it means opening the refrigerant side of the system. A failing compressor or a blocked outdoor unit can also cause this. Check the filter first, and if it's clean, the system needs a licensed contractor to find out what's wrong.
- Why is my AC leaking water?
- Most of the time this means the condensate drain line is clogged, so water backs up instead of draining outside. It can also mean the coil has frozen and is now melting, usually because airflow across it was restricted by a dirty filter or low refrigerant. A cracked drain pan will leak too, especially on an older unit. Clear the filter and check for ice on the coil, and if the leak continues, have someone look at the drain line and pan.
- Why won't my AC turn on?
- Start with the thermostat. Check that it's set to cool, the temperature is below room temperature, and the batteries aren't dead. If the thermostat looks right, check the breaker, since a tripped breaker will shut the whole system down. Aberdeen has had 187 damaging wind events over the past ten years, and storms like that can trip a breaker or damage the outdoor unit's power connection. If the breaker is fine and the thermostat is set correctly, the problem is likely inside the unit and needs a contractor to diagnose.
