Takes about a minute. No obligation.

A mini-split compressor in Florence County starts and stops on a real schedule, not an occasional one. Homes in Florence County, SC run cooling about five months a year, from May through September. Repeated cycling across those months loads the contactor, stresses the refrigerant circuit, and wears the fan bearings in the outdoor unit. A contractor diagnosing a repair here checks those parts before anything else, because the operating history backs it up. A unit that ran through every one of those months without service shows that wear in the refrigerant pressures and in the contactor pitting a technician finds on the first inspection.

Refrigerant lines corrode, drain pans crack, and compressor windings degrade in ways that have everything to do with how long a system has been asked to compensate for a structure it was retrofitted into. Half the homes in Florence County, South Carolina were built in 1986 or earlier (2020-2024 ACS 5-year). That means a contractor opening a mini-split here expects to find wear signatures shaped by a long service history in housing that was not originally designed around it. The condition of the evaporator coil, the state of the condensate drain, and whether the lineset has been disturbed or patched over the years are what determine the repair scope. Parts availability for systems that have been running in this stock for a long stretch is a real variable too, and it changes both what gets ordered and how long the job takes to close.
The Parts of a Mini-split a Contractor Checks First

The indoor air handler mounts high on an interior wall and pushes conditioned air directly into the room. Its evaporator coil, fan, and drain line are the first things a contractor looks at when a room stops cooling or heating properly, because a fault in any one of them shows up fast.
The outdoor condenser unit sits on a pad or bracket outside the house and holds the compressor and the condenser coil. The refrigerant lines and the communication wiring run between the two units through a small penetration in the wall, and both are checked when the indoor and outdoor sides are not talking to each other correctly.
