Five months of heat, then hail and wind
Your air conditioner runs from May through September here, with summer afternoons averaging 86°F. That is five months of steady work for the compressor and the fan before it gets a break.
Clay County has also seen 94 hail events and 116 damaging wind events over the past ten years, with hail as large as 2.75 inches. Hail dents the fins on your outdoor unit and can bend the coil behind them, and wind strong enough to cause damage can knock the unit out of level or drive debris into it. A tune-up checks the fins and coil and makes sure the unit still sits level before the next stretch of hot afternoons.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
- What does AC maintenance include?
- A contractor checks refrigerant charge, cleans the condenser coil, and tests the capacitor and contactor in the outdoor unit. Inside, they check the evaporator coil, the blower, and the condensate drain to make sure it isn't clogged. They also check the filter and the thermostat's operation, and take amp readings on the compressor and fan motor to see if either is under strain. Any of these can cause a breakdown on its own, so checking each one matters more than treating it as a single task.
- How often does an air conditioner need maintenance?
- Once a year, before the cooling season starts. Homes here run their AC May through September, so a visit in spring catches problems before the system has to work through summer afternoons that average 86°F. A dirty coil or a weak capacitor found then is easier to deal with than one that fails while the system is running every day.
- Is AC maintenance worth it?
- Yes, because most of what causes a summer breakdown builds up slowly and shows up in a maintenance check first. A weak capacitor, a coil losing airflow, or refrigerant slipping low will all show measurable signs before the unit quits outright. Catching them ahead of time means the system isn't struggling through five months of cooling season on a part that's already failing.
