A contractor quoting a central AC install in Tippecanoe County sizes for what the equipment will actually run against, not what a catalog assumes. 126 severe weather events were recorded in Tippecanoe County, Indiana between 2015 and 2024. At that rate, severe weather is a standing condition, and a unit specified without accounting for it will be working against its own design from the first season. Duct routing, equipment placement, and electrical connections all get weighed against what this area puts a system through. A contractor who treats those as standard decisions is leaving the local record out of the job.
Ductwork laid down for an older generation of equipment carries assumptions about static pressure, trunk sizing, and return-air placement that do not always transfer to a modern central AC unit. Half the homes in Tippecanoe County, Indiana were built in 1987 or earlier (2020-2024 ACS 5-year). That puts the existing duct system at the center of what a contractor has to evaluate before the new equipment is even selected. Electrical service matters too, but ductwork is where mismatches between the original construction and a new system show up as real problems: undersized returns, restricted supply runs, or branch layouts that prevent balanced airflow across the house.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and holds the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil lives in a utility space, basement, or attic. Together these two pieces form the core of the system a homeowner is buying.
A refrigerant line set runs between the indoor and outdoor units, connecting them through an exterior wall. The thermostat mounts on an interior wall and gives the homeowner control over the whole system. A contractor also ties the system into the existing condensate drain to carry away moisture the indoor coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the specifics of 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 Tippecanoe County
Weather in Tippecanoe County puts real demand on cooling equipment, and that demand shapes what a system needs to handle over its life. How hard a central AC works, and how reliably it has to do it, is a local question.
