Two short months, then it sits idle
Your air conditioner only earns its keep from July through August here. Summer afternoons average 81°F, nothing extreme, so the unit isn't run hard the way it would be further south. But that also means it spends ten months a year doing nothing at all, sitting outside through whatever the weather brings.
And Custer County brings a lot. The last ten years saw 244 hail events and 158 damaging wind events. Hail up to 2.75 inches can bend the fins on the outdoor coil, and wind carries branches and grit into the cabinet. None of that announces itself. A tune-up checks the coil and the fins for damage, confirms the refrigerant charge, and makes sure the unit is ready before that short window arrives, so it isn't the first hot day that tells you something's wrong.

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.
South Dakota has no state license for HVAC contractors. Whether this contractor is licensed depends on the city or town, not the state. There is no state board testing contractors or keeping a record of them. Whatever rule applies here comes from the city or town, if one exists at all.
For a maintenance visit on an air conditioner, the protection that reaches this job either way is federal. Any technician who checks refrigerant or works on the sealed side of the system must hold EPA Section 608 certification. That rule holds in every state, regardless of what South Dakota or the local government require. It is the one credential this job is guaranteed to touch.

- What does AC maintenance include?
- A technician checks refrigerant charge, cleans the condenser coil, and tests the capacitor and electrical connections. They also check the condensate drain for clogs and confirm the system is cycling correctly. Anything involving the refrigerant side has to be handled by someone with an EPA Section 608 certification, which is a federal requirement everywhere. The filter matters too, but that's something a homeowner can check between visits.
- How often does an air conditioner need maintenance?
- Once a year, before the weather turns warm, is enough for most systems. Here, cooling season only runs July through August, so getting a checkup done in late spring gives a contractor time to catch anything before those two months hit. A yearly visit is also when a dirty coil or a weak capacitor gets caught before it causes a breakdown in the middle of a hot stretch.
- Is AC maintenance worth it?
- Yes, because most of what causes a system to fail in summer is something a checkup would have caught. A dirty coil, a failing capacitor, or a low refrigerant charge all make the compressor work harder, and that's what shortens its life. With summer afternoons here averaging 81°F, a system that's already stressed has less room to keep up when it needs to. Maintenance is also when a technician notices small problems, like a fraying wire or a clogged drain, before they turn into a no-cool call.
