Three months of hard work, then a long rest
Your air conditioner in Aberdeen earns its keep June through August. Afternoon highs near 81°F mean the compressor cycles on and off for hours most summer days, and it has to keep up every time it starts.
Then it sits idle the rest of the year. Dust settles on the coil while the unit is off, and refrigerant can seep down over months of no use. A tune-up before summer checks the refrigerant level and cleans the coil so the compressor isn't working harder than it needs to once the heat sets in. Brown County also sees its share of hail and wind. Ten years of storm records show 99 hail events and 187 damaging wind events in the area, and a unit that took a hit last summer may not show it until it's straining to cool the house this one.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
In South Dakota, HVAC licensing for homes is left to the cities and towns.
Brown County does not run its own HVAC licensing program, so there is no city or county credential standing behind a contractor working here the way there would be in a town that licenses. That leaves this as a case where the state points to local rule, and the local rule here does not fill the gap.
For a maintenance visit on an air conditioner, the piece that does apply everywhere, including Brown County, is federal. Anyone who opens the refrigerant side of the system, to check the charge or get into the coil, has to hold EPA Section 608 certification. That is not a state or local license. It is a federal card tied to the person, not the business, and it is the one credential you can count on regardless of where in South Dakota the house sits.

- What does AC maintenance include?
- A technician checks the refrigerant charge, cleans the condenser coil outside, and tests the capacitor and contactor that get the compressor running. They also clear the condensate drain so it doesn't back up, and confirm the thermostat is calling for cooling correctly. Anything involving the refrigerant side has to be done by someone with an EPA Section 608 certification, which is a federal rule everywhere. Outside, they'll also look over the cabinet and fins, since Aberdeen has seen 99 hail events and 187 damaging wind events over the past ten years, and either can leave marks on a unit that sits outside all year.
- How often does an air conditioner need maintenance?
- Once a year is standard, ideally before the first hot stretch. In Aberdeen that means getting it done in spring, since cooling season here runs June through August. A yearly check catches a weak capacitor or a low refrigerant charge before an 81°F afternoon turns it into a no-cool call.
- Is AC maintenance worth it?
- Yes, because most AC failures trace back to something a technician would have caught during a routine check, like a failing capacitor or a coil so dirty the system has to work harder than it should. Aberdeen only gets three months of real cooling weather, June through August, so a unit that fails partway through that stretch still leaves a house without air conditioning when it's needed most. A yearly visit catches the small problems before they turn into that kind of failure.
