A contractor quoting a central AC installation in Scott County is not working around a relentless weather record. 45 severe weather events were recorded in Scott County, Indiana between 2015 and 2024. At that rate, severe weather is an occasional event in a system's life, not a standing condition it has been grinding against. What drives sizing decisions and installation quality here is the age and layout of the house, how well the existing ductwork moves air, and how much cooling load the structure actually demands on a peak summer day. Get those wrong and the system underperforms from day one, regardless of what the sky does.
Ductwork laid down when a house was first built was sized and routed for whatever the builder spec'd at the time, and the electrical service matched it. Half the homes in Scott County, Indiana were built in 1983 or earlier (2020-2024 ACS 5-year). A contractor quoting a new central AC system in stock like this has to assess both before the equipment selection means much: whether the existing duct runs can move the volume a modern unit delivers, and whether the panel will carry the load without an upgrade. Those two variables, not the equipment itself, are what set the scope and the final cost of the job.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad outside the house and holds the compressor and condenser coil, the two components that shed heat to the outside air. Inside, the air handler or furnace cabinet stands in a utility space, basement, or closet and holds the evaporator coil that pulls heat from your indoor air.
The refrigerant line set runs between those two units, a pair of copper lines that carry refrigerant back and forth through the wall or floor. A thermostat mounts on an interior wall and is the control point a contractor wires to the rest of the system so the whole thing runs as one.
The drawing shows a typical layout, and a licensed contractor determines what fits the specifics of your house.

What the installation looks like from your end
Split-system central air conditioners rated below 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners rated at or above 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners manufactured between January 1, 2015 and December 31, 2022 had to meet 13 SEER, the metric that preceded SEER2.
Single-package central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Space-constrained central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 11.7 SEER2.
Federal efficiency standards for split-system central air conditioners and heat pumps are set on each certified combination of outdoor unit and indoor coil rather than on the outdoor unit alone.
Residential and light commercial air conditioning and heat pump systems assembled in the field, including mini-splits and unitary systems, may not be installed on or after January 1, 2025 using a refrigerant with a global warming potential above 700.
A field-assembled system whose specified components were all manufactured or imported before January 1, 2025 carries no installation compliance date under the refrigerant restrictions and may still be installed.
Severe Weather Events in Scott County
Weather puts a load on cooling equipment, and that load is shaped by what actually happens in this area. A central AC system sized and installed for local conditions handles real demand better than one spec'd to a national average.
