Five months of hard running takes a toll

Your air conditioner works May through September here, and on afternoons pushing 88°F it runs long stretches just to keep up. That kind of steady demand wears on the parts that keep it cooling, the capacitor, the contactor, the fan motor.

Cape Girardeau County has also seen 23 hail events and 120 damaging wind events over the past ten years, with hailstones up to 1.75 inches. That kind of weather can bend fins on the outdoor coil or knock the unit out of level without you knowing it happened. A tune-up checks the coil, the refrigerant charge, and the electrical connections before a small problem turns into a system that won't start on the hottest day of the year.

5 months: May through September, your air conditioner is on duty
88°F: the average summer afternoon it cools against
23 hail events: in ten years, and hail bends the fins on outdoor coils
120 wind events: in ten years, and wind drives debris into outdoor units

Book your AC tune-up in April, before homes here start needing cooling in May.

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 the refrigerant charge, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. Inside, they check the evaporator coil and the condensate drain, since a clogged drain is one of the more common reasons an AC stops cooling mid-summer. They also check that the thermostat is calling for cooling correctly and look at the electrical connections for wear. None of this takes long, but it catches the small failures before they turn into a system that quits in the middle of summer.
How often does an air conditioner need maintenance?: Once a year, ideally in spring before the cooling season starts. Here that means getting it done before May, since homes run the AC from May through September and summer afternoons average 88°F. A unit that sits unused all winter needs that check before it has to work its hardest.
Is AC maintenance worth it?: Yes, because most breakdowns trace back to something a technician would have caught. A dirty coil, a weak capacitor, or a low refrigerant charge all make the system work harder and fail sooner, and a routine check catches these before they become a bigger problem. It matters more here than in milder climates too. Cape Girardeau has seen 120 damaging wind events and 23 hail events over the last ten years, and a yearly check is when a technician would notice a bent fin or a coil that took a hit.
