Two months of hard work, and a lot of hail in between
Your air conditioner in Gillette only has to earn its keep in July and August, with afternoons averaging 83°F. That is not a long season, but it is a demanding one. The unit sits idle most of the year, then gets asked to run hard for two months straight.
What happens outside those two months matters just as much. Campbell County has logged 213 hail events and 202 damaging wind events over the past ten years, with hailstones up to 3 inches. That kind of weather bends fins, dents the cabinet, and can knock coils and wiring around even when the system is off. A tune-up before summer checks the coil and refrigerant charge, and it is also the point where a contractor spots the kind of hail or wind damage that is easy to miss until the unit is asked to run.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
- What does AC maintenance include?
- A technician checks refrigerant charge, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. They also check the evaporator coil, change or check the filter, and confirm the thermostat is calling for cooling correctly. Part of the visit is just looking the unit over for anything hail or wind may have bent or loosened, since that matters here. The point of the visit is to catch a weak part before it fails in the two months you actually need the system running.
- How often does an air conditioner need maintenance?
- Once a year, in spring before the heat sets in. Gillette only asks the system to run in July and August, but the coil and capacitor still sit outside all year taking wind and hail. One visit before summer catches anything that shifted over the winter, before you need the air conditioner every day.
- Is AC maintenance worth it?
- Yes, especially with the weather here. Gillette has logged 213 hail events and 202 damaging wind events over the past ten years, and an outdoor condenser coil bent by hail or debris loses efficiency even when the unit still runs. A yearly check catches that kind of damage along with normal wear like a weak capacitor, before the unit fails on one of the hot afternoons you actually need it.
