A mini-split in Horry County works its compressor, coil, and contactor hard from the first warm day through the last. Homes in Horry County, SC run cooling about five months a year, from May through September. Contactor pitting, refrigerant line stress, and coil fouling build across that stretch in ways that show up clearly when a technician pulls the covers. A contractor diagnosing a repair here starts with the compressor and its refrigerant circuit, because those parts absorb the bulk of the seasonal load and fail in patterns a visual inspection and pressure check can confirm before anything else gets quoted.

Half the homes in Horry County, South Carolina were built in 1999 or earlier (2020-2024 ACS 5-year). For a mini-split repair in stock like this, what matters is what the technician finds once the unit is open: whether the refrigerant type the system runs on is still sourced locally, whether the control board or compressor has a replacement available, and whether the wear on the internal components reflects years of running harder than the original spec assumed. A house that old can hold a system of almost any age, so the repair scope is set by what is actually inside the cabinet, not by anything visible from the street.
The Parts of a Mini-split a Contractor Checks First

The indoor air handler mounts high on a wall inside the room and is the piece a homeowner sees every day. Its fan, coil, and filter work together to move conditioned air into the space, so when airflow drops, temperatures swing, or frost builds up on the unit, that handler is where a contractor starts.
The outdoor condenser sits on a pad or bracket outside the house and holds the compressor and the condenser coil. A refrigerant line set and a drain line run between the two units through a small opening in the wall, and the condenser is the second place a contractor looks when the indoor unit checks out fine.
The drawing shows a typical layout, and a licensed contractor determines what applies to the specific system and home.
