A contractor quoting a central AC install in Wabash County has to account for what the existing equipment was actually asked to do before it gave out. 46 severe weather events were recorded in Wabash County, Indiana between 2015 and 2024. At that rate, severe weather is an occasional event rather than a standing condition, which means a failed or undersized system here most often traces back to how it was originally sized and installed, or to years of deferred maintenance. A new install is sized around the demands of the house and the local cooling season, not around a storm history that has not been the dominant load.
Ductwork laid out for an earlier era of home cooling shapes what a central AC installation actually involves here. Half the homes in Wabash County, Indiana were built in 1959 or earlier (2020-2024 ACS 5-year). Ducts sized and routed for the equipment of that period were built to different airflow standards than a modern central AC unit runs on, and a contractor has to assess what is already in the walls and crawlspaces before the equipment choice means much. The electrical service in houses of that vintage is the other variable, since the draw of a new system has to match what the panel can carry.
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. The indoor air handler or furnace-and-coil combination goes inside, often in a basement, utility closet, or attic, and is the piece that moves conditioned air into the duct system.
The evaporator coil mounts directly above the furnace or inside the air handler and is where the refrigerant lines connect the two main units together. A thermostat goes on an interior wall and gives the homeowner control over the whole system. The refrigerant lineset runs between the indoor and outdoor units, and a condensate drain line carries moisture out of the house.
The drawing shows a typical layout, and a licensed contractor determines what fits and what applies in your specific home.

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 Wabash County
Weather swings put real load on central AC equipment, and what a system handles in Wabash County shapes how it should be sized and installed. A contractor who knows this area accounts for local conditions, not just a generic specification.
