A contractor quoting a central AC installation in Pulaski County is not solving a heavy-weather problem. 30 severe weather events were recorded in Pulaski County, Indiana between 2015 and 2024. At that rate, severe weather is an event, not a condition, and it does not drive the decisions that matter most on an install job here. Sizing, equipment selection, and duct quality are what separate a system that runs well from one that struggles, and none of those depend on storm history. The load this climate puts on a new unit is modest, so the contractor's attention goes to the house itself.
Ductwork sized and routed for older equipment often cannot move the air volume a new central AC unit is built to push, and that gap is what drives the real scope of an installation job in this county. Half the homes in Pulaski County, Indiana were built in 1970 or earlier (2020-2024 ACS 5-year). A house that old was planned around assumptions about system capacity that contractors no longer work to, which means the duct layout gets evaluated before the equipment is ever priced. If the runs are too narrow, too long, or poorly branched, putting a new unit on them produces uneven cooling and shortened equipment life. The electrical service gets the same look, since a modern compressor draws differently than what the house was originally wired for.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and houses the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil sits in a utility space, basement, or closet and is where the system draws heat out of the air before pushing it back through the house.
A refrigerant line set runs between the two units, connecting the indoor and outdoor sides through the wall or floor. The thermostat mounts on an interior wall and is the control point a homeowner sees and uses every day.
The drawing alongside shows a typical layout, and a licensed contractor determines exactly what applies to your house.

What the installation actually looks like
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 Pulaski County
Weather swings put real load on cooling equipment, and how hard a system works over its life depends on what the local climate demands of it. Central AC installation in Pulaski County is a decision shaped by those local conditions, not by national averages.
