Five months of hard running in Lexington County heat
Your air conditioner works May through September here, and summer afternoons average 91°F. That is five months of long, steady run time, not short bursts. The compressor and the fan motor spend whole afternoons working instead of cycling on and off, and that steady load is what wears them down.
A tune-up before the season checks the refrigerant charge, cleans the outdoor coil, and tests the capacitor that helps the compressor start. A coil coated in dust cannot shed heat well, and a weak capacitor is a common reason a unit will not start on the first hot day. Catching either one in the spring means it does not fail on the afternoon you need the cooling most.

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 outdoor coil, tightens electrical connections, and tests how the system starts and cycles off. They also check the capacitor and contactor, since those parts wear out from the number of times the system cycles on rather than from age alone. The filter gets checked too, since a clogged one makes the whole system work harder. In Lexington, where the system runs from May through September, that coil often needs a real cleaning by mid-summer, not just a glance.
- How often does an air conditioner need maintenance?
- Once a year, before the season it works hardest in. Here that means getting it looked at in spring, ahead of the stretch from May through September when afternoons average 91°F. A yearly check catches a weak capacitor or a dirty coil before it causes a breakdown on a hot afternoon.
- Is AC maintenance worth it?
- Yes, because most breakdowns start as a small problem that a technician can catch early. A weak capacitor, a coil losing airflow, a low refrigerant charge all show up during a maintenance visit long before they'd cause the system to quit outright. In a place like Lexington, where summer afternoons run hot and thunderstorms bring hail and high wind, having the outdoor unit checked also means someone will notice bent fins or debris in the cabinet before it turns into a bigger repair.
