Five months of 90 degree afternoons wear on a system

From May through September your air conditioner is working most days, and Sumter summer afternoons average 90°F. That kind of heat means long run times, and long run times wear on the parts that keep the unit running, the capacitor, the contactor, the condenser fan motor.

A tune-up before the season catches a weak capacitor or a dirty condenser coil while the system can still handle it. Sumter has also logged 182 damaging wind events and 24 hail events over the past ten years, with hail up to 1.75 inches. A service check gets eyes on the outdoor unit and finds bent fins or a cracked line before they turn into a system that can't keep up on the next 90 degree day.

5 months: May through September, your air conditioner is on duty
90°F: the average summer afternoon it cools against
24 hail events: in ten years, and hail bends the fins on outdoor coils
182 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 for wear. They also check the blower motor, clear the condensate drain, and swap or clean the filter. Outside, the condenser unit gets checked for debris, since it sits outdoors and collects grass, leaves, and dirt over the season. Inside, they check that the coil is draining properly and that airflow through the ducts is even.
How often does an air conditioner need maintenance?: Once a year is what most manufacturers ask for, done before the season it works hardest. Here that means getting it checked before May, since the unit runs from May through September and summer afternoons average 90 degrees. A yearly check catches a weak capacitor or a dirty coil before it fails on a 90 degree day.
Is AC maintenance worth it?: Yes, because most failures start small and get caught during a check before they leave you without cooling. A dirty coil or a failing capacitor still runs, but it runs harder and wears out other parts faster. With five months of cooling season here and summer afternoons averaging 90 degrees, a unit that is struggling has no easy months to recover in.
