Five months of Anderson summer adds up

Your air conditioner runs from May through September here, and on the afternoons that hit 89°F it doesn't get much of a break. That's the stretch where a weak capacitor or a dirty coil turns into a system that runs long and still can't keep the house cool.

Anderson County has also logged 33 hail events and 111 damaging wind events over the past ten years, with hail up to 1.75 inches. That kind of weather can bend the fins on your outdoor unit or knock it out of level, and it's not something you'd notice from inside the house. A tune-up is when someone checks the coil, the fins, and the refrigerant charge before the summer heat finds whatever the storms left behind.

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 in the outdoor unit. Inside, they check the evaporator coil, change or check the filter, and look at the blower. They also check the thermostat and confirm the drain line is clear so the system does not back up. A dirty coil or low refrigerant charge shows up as higher bills and a system that struggles to keep up on the hot afternoons here.
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 the system will run through September without much of a break. A yearly check catches a weak capacitor or a low refrigerant charge before it causes a breakdown during the hottest stretch of summer.
Is AC maintenance worth it?: Yes, because most breakdowns trace back to something a maintenance visit would have caught. A dirty coil, a failing capacitor, or a clogged drain line all get worse under load, and air conditioners here carry that load for five months a year with afternoons averaging 89°F. Catching a weak part in spring means it fails on a technician's schedule, not on the hottest day of summer.
