Step 1 of 3: Equipment
A two-story gray horizontal-siding house with multiple gables, a covered front porch with white columns and railing, and a dark front door, fronted by a patchy green and brown lawn under a clear blue sky.

Sizing a central AC unit for this area starts with what the compressor is actually asked to do and when. Homes in Rush County, KS run cooling about four months a year, from June through September. Across those months, the compressor cycles repeatedly through heat and load, then sits dormant for the rest of the year. Long idle periods let refrigerant seep past worn seals and let contactors corrode without tripping any symptoms. A contractor quoting a new install here accounts for that dormancy when selecting equipment and specifying the refrigerant circuit, because a system that starts cold after months off puts a different kind of stress on components than one that runs year-round.

Ductwork laid down for one era of equipment does not automatically serve the next. Half the homes in Rush County, Kansas were built in 1948 or earlier (2020-2024 ACS 5-year). That gap between when a house was built and what a contractor now installs into it is where the installation job actually lives, and it shows up in the duct runs before it shows up anywhere else. A house whose original trunk lines were sized for a different load may need rebalancing, rerouting, or supplementing before the new unit performs as rated. The electrical service tells its own story. A contractor scoping a central AC installation here reads both before a unit gets ordered.

What Central AC Involves With a New Installation

Isometric cutaway illustration of a house interior showing ducted air handling equipment and duct runs through rooms, connected by piping to an outdoor condenser unit on a pad outside the wall.

The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and holds the compressor and the coils that shed heat to the outside air. The indoor air handler or furnace sits inside, most often in a utility closet, basement, or attic, and pushes conditioned air through the house.

The evaporator coil mounts directly above the air handler and is where the refrigerant does its work on the air passing over it. A refrigerant line set runs between the two units, and a condensate drain carries moisture away from the indoor side.

The drawing shows a typical layout, and a licensed contractor determines what fits the specifics of your house.
