A contractor quoting central AC installation in Hancock County has to size for a climate that is neither punishing nor forgiving. 91 severe weather events were recorded in Hancock County, Indiana between 2015 and 2024. At that rate, severe weather is an occasional fact of life rather than a standing condition, and it does not explain most of what goes wrong with residential cooling equipment here. Poor installation decisions and deferred maintenance do. A contractor who accounts for local load conditions will specify equipment accordingly, but the bigger variable is how well the system goes in.
Ductwork laid out for older cooling loads may not move air the way a current central AC system needs it to. Half the homes in Hancock County, Indiana were built in 1991 or earlier (2020-2024 ACS 5-year). A contractor installing new equipment in this county has to check whether existing runs, trunk lines, and return paths will carry the new system's airflow before the unit itself can be quoted. The electrical is a separate question, and in stock of this vintage the service panel warrants a look too. What the house already contains sets the scope 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, which are the core of the system. Inside, the air handler or furnace with an evaporator coil mounts in a mechanical room, basement, or utility closet and is the piece that actually conditions the air moving through the house.
A refrigerant line set runs between the two units, connecting the indoor and outdoor sides through a wall or floor penetration. The thermostat mounts on an interior wall and is the control point the homeowner uses to tell the system what to do.
The drawing shows a typical layout, and a licensed contractor determines what the installation looks like for this specific 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.
