Five months of Greenwood summer heat adds up

Your air conditioner runs from May through September here. Summer afternoons average 90°F, and the system has to hold that back for five straight months.

A tune-up checks the parts carrying that load. The refrigerant charge, the condenser coil, the electrical connections that keep the compressor running. Greenwood County has also logged 53 damaging wind events and 8 hail storms over the past ten years, one with hail up to 1.75 inches. That kind of weather can knock the condenser out of true or nick the coil fins, and a maintenance visit is when a contractor catches it.

5 months: May through September, your air conditioner is on duty
90°F: the average summer afternoon it cools against
8 hail events: in ten years, and hail bends the fins on outdoor coils
53 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 level, cleans the outdoor coil, and tests the capacitor and contactor that start the compressor. They also check the airflow across the indoor coil and clean or replace the filter if it needs it. They should also check the electrical connections and the condensate drain, since a clogged drain can back up and cause water damage.
How often does an air conditioner need maintenance?: Once a year is enough for most homes. The best time is before the cooling season starts, so any issue gets caught before the unit runs hard. Homes here run the AC five months a year, from May through September, with summer afternoons averaging 90°F, so a unit that goes into that stretch unmaintained has to work through the hottest months with whatever problem was missed.
Is AC maintenance worth it?: Yes. A maintenance visit catches a failing capacitor or a low refrigerant charge before it turns into a breakdown on a 90°F afternoon. It also keeps the coil clean, and a dirty coil makes the compressor work harder to move the same amount of heat. Skipping it does not damage the unit right away, but small problems tend to get worse under the load of a full cooling season.
