Step 1 of 3: Equipment

What kind of equipment?*

A two-story beige house with gabled roofs and a light-colored front door, fronted by a lawn with a running sprinkler, a concrete walkway, sidewalk and wet street, flanked by large green deciduous trees in low sunlight.

Sizing a central AC system for this county starts with the actual load the compressor will carry through the heat of summer, because an undersized unit runs longer cycles and starts more often than its components were rated for. Homes in Osage County, MO run cooling about four months a year, from June through September. A compressor working that hard, that many days in a row, wears its contactor and its motor windings at a rate a generous install would not produce. A contractor who skips the load calculation and pulls a unit off the shelf is not cutting a corner that stays hidden. It shows up in the compressor.

Unfinished basement with concrete block walls, a bare concrete floor, exposed wood floor joists, and insulated metal ductwork running along the ceiling, with two cardboard boxes and a coiled gray flexible hose on the floor.

Ductwork sized and routed for whatever system a house was built around does not automatically suit what a contractor is putting in now. Half the homes in Osage County, Missouri were built in 1982 or earlier (2020-2024 ACS 5-year). A licensed contractor quoting a central AC installation here measures the existing duct runs before anything else, because the gap between what those runs were designed to move and what a new system needs to move is where jobs get complicated. If the ductwork clears that check, the electrical service gets the same scrutiny.

The Parts of a Central AC System Being Installed

Isometric cutaway illustration of a small house showing interior rooms with furniture, an indoor air handler with ducts in the attic space, and refrigerant lines running to an outdoor condenser unit on a pad.

The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, which are the core of the system. Inside, the air handler or furnace-mounted evaporator coil lives in a mechanical room, basement, or closet, and is where the indoor side of the refrigeration circuit lives.

The refrigerant line set runs between the two units, connecting outdoor to indoor through a pair of copper lines that pass through an exterior wall. A thermostat mounts on an interior wall and gives the homeowner control over the whole system.

The drawing shows a typical layout, and a licensed contractor determines what applies to your house specifically.
