A contractor quoting a central AC installation in Floyd County is not sizing against a punishing weather history. 76 severe weather events were recorded in Floyd County, Indiana between 2015 and 2024. At that rate, severe weather is an occasional event here rather than a standing condition, which means the equipment a contractor is replacing has been living and dying by how well it was sized and installed the first time. Undersized equipment, poor refrigerant line runs, and inadequate airflow do more damage to a system in this county than the weather record does. That is what a contractor has to get right on the new install.
Ductwork runs laid down for older equipment carry different dimensions, materials, and static pressure assumptions than a new central AC system asks of them. Half the homes in Floyd County, Indiana were built in 1980 or earlier (2020-2024 ACS 5-year). A contractor pricing an installation here sizes the new unit against what the existing trunk lines and branch runs can actually move, and in stock of this vintage that calculation regularly turns up ductwork that needs modification or replacement before the new system can perform. The electrical is a second checkpoint: service panels in houses of this era were not always wired for the loads a modern condenser draws.
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-mounted evaporator coil lives inside, most often in a basement, utility closet, or attic, and is the point where cooled air enters the duct system.
A refrigerant line set runs between the two units, connecting the outdoor and indoor sides through the wall or floor. The thermostat mounts on an interior wall and serves as the control point for the whole system, telling the equipment when to run.
The drawing shows a typical layout, and a licensed contractor determines exactly what the installation involves in your house.

What HVAC Installation Looks Like in Floyd County
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.
