Five months of hard running in Warrensburg heat

Your air conditioner works May through September here, and on those 87°F afternoons it runs long and hard to keep up. That kind of stretch wears on the parts that keep it cooling, the capacitor that gets the compressor going, the contactor that switches it on and off, the coil that has to stay clean to shed heat.

Johnson County has also seen 73 hail events and 61 damaging wind events over the past ten years, with hail up to 2.5 inches. That kind of weather can bend the fins on your outdoor unit or knock it out of alignment without you noticing right away. A tune-up catches a weak capacitor or a bent coil before the compressor is working against them, and before a hot afternoon is the day it finally quits.

73 hail events: in ten years, and hail bends the fins on outdoor coils
61 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 refrigerant pressure, cleans the condenser coil, and tests the capacitor and contactor. They also inspect the fan motor, clear the condensate drain, and check the electrical connections for wear. Outside, the condenser sits exposed to weather all year, so part of the visit is making sure nothing around it is loose or corroded. The filter gets checked too, since a clogged one makes the whole system work harder.
How often does an air conditioner need maintenance?: Once a year, before the cooling season starts. Homes here run the AC from May through September, so a spring checkup catches problems before the heat sets in. Waiting until the system is already running hard to find out the capacitor is weak means going without cooling until someone can get to it.
Is AC maintenance worth it?: Yes, because it catches small problems while they are still small. A weak capacitor, a low refrigerant charge, or a dirty coil all make the system work harder and wear out faster, and a technician can spot each one during a routine visit. With summer afternoons here averaging 87°F for five months straight, the system runs hard all season, and a unit that starts in good shape is less likely to fail in the middle of it.
