Step 1 of 3: Equipment

What kind of equipment?*

Single-story red brick house with a gray shingled roof, white-framed windows and a glass front door, fronted by a large asphalt driveway with sun glare, surrounded by green trees and shrubs.

Sizing a central AC system for this house requires a load calculation that accounts for what the compressor will actually be asked to do each year. Homes in Laurens County, SC run cooling about five months a year, from May through September. A contactor and condenser fan cycling through that stretch accumulate wear in a way that a marginal install cannot hide. A system sized short runs longer per cycle, starts more often, and stresses the compressor before the homeowner has any reason to suspect a problem. A contractor quoting a new installation here factors that runtime into equipment selection from the start.

Ductwork sized for an older, lower-capacity system does not automatically carry what a current central AC unit needs, and that gap is where an installation job gets complicated or stays straightforward. Half the homes in Laurens County, South Carolina were built in 1985 or earlier (2020-2024 ACS 5-year). A contractor quoting a new system here has to assess whether the existing duct layout moves enough air for the load a modern unit puts on it, and whether the electrical service handles the draw. Those two answers shape the job more than the unit selection does.

What Gets Installed With a New Central AC

The outdoor unit sits on a concrete pad beside the house and holds the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil lives in a closet, attic, or utility room. These two units are the core of what a contractor puts in place.

A refrigerant line set runs between the indoor and outdoor units, connecting them through an exterior wall. The thermostat mounts on an interior wall and gives the homeowner control over the whole system. Both pieces are part of a new installation.

The drawing shows a typical layout, and a licensed contractor determines exactly what fits this house.
