A contractor quoting central AC in Whitley County starts by sizing the system to the house, because the local weather record is real but not extreme enough to override that calculation. 78 severe weather events were recorded in Whitley County, Indiana between 2015 and 2024. At that rate, severe weather is an event in the life of a system here, not a constant pressure on it. Age of the home, duct condition, and the quality of the original install drive how a replacement job gets planned far more than storm history does.
Ductwork laid down for the equipment that was standard when much of this county's housing stock was built was sized and routed for different demands than a modern central AC system makes. Half the homes in Whitley County, Indiana were built in 1979 or earlier (2020-2024 ACS 5-year). A contractor pricing an installation here has to open access points and measure what the existing duct network can actually move before the equipment choice becomes meaningful. If the runs are too long, the returns too few, or the sizing off for the loads a new unit will generate, the duct system sets the ceiling on what any new equipment can deliver. The electrical service gets the same look, since the draw a current-generation system requires may not match what the panel was wired to handle.
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 do the heaviest work in the system. Inside the home, the air handler mounts in a utility space, basement, or attic and moves conditioned air through the house. These are the main pieces a homeowner is buying.
The expansion valve and evaporator coil live inside or directly upstream of the air handler, where they work with the refrigerant line set that runs between the indoor and outdoor units. The thermostat goes on an interior wall and gives the homeowner control over the whole system.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this 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 Whitley County
Weather puts a measurable load on cooling equipment, and that load varies by where you live. A central AC system sized and installed for conditions in Whitley County will run differently than one built for somewhere else.
