Two months of heat, and hail before it

Your air conditioner in Sundance only has to earn its keep in July and August, with afternoons averaging 82°F. That short season is easy on the compressor compared to hotter places, but it means the unit sits idle most of the year, and a system that's been idle can hide a problem until the first hot day asks something of it.

The bigger risk here comes from above. Crook County has logged 183 hail events and 123 damaging wind events over the past ten years, with hailstones as large as 3.25 inches. That kind of hail bends the thin aluminum fins on your condenser coil, and bent fins block airflow the unit needs to cool properly. A tune-up checks the coil and fins for that kind of damage, along with the refrigerant charge and electrical connections, before the two months you actually need cooling arrive.

2 months: July through August, your air conditioner is on duty
82°F: the average summer afternoon it cools against
183 hail events: in ten years, and hail bends the fins on outdoor coils
123 wind events: in ten years, and wind drives debris into outdoor units

Book your AC tune-up in June, before homes here start needing cooling in July.

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 cleans the condenser coil outside, checks the refrigerant charge, and tests the capacitor and contactor in the electrical parts. They also check the blower and the evaporator coil inside, and check that the thermostat is calling for cooling correctly. Since your cooling season here is short, from July through August, this checkup is worth scheduling in the late spring so everything is ready before the heat sets in.
How often does an air conditioner need maintenance?: Once a year is enough for most systems. The best time is before your cooling season starts, so a spring checkup before the July through August heat catches anything that needs attention while it is still easy to schedule. A system that only runs two months a year still sits idle the other ten, and a checkup makes sure it starts up clean when you need it.
Is AC maintenance worth it?: Yes, because it catches small problems, a weak capacitor or a dirty coil, before they cause a breakdown on a hot afternoon. With summer highs here averaging 82°F, an air conditioner that is not working at full capacity will struggle to keep up on the warmest days. A yearly checkup also keeps the coil clean, and a clean coil lets the system cool the house without working harder than it has to.
