A contractor quoting a central AC installation in Parke County has to work out what this building actually demands before picking equipment. 33 severe weather events were recorded in Parke County, Indiana between 2015 and 2024. At that rate, severe weather is a real but occasional feature of life here, not a constant operating pressure that overrides every other sizing consideration. What drives the right equipment choice is the building's load profile, the condition of the existing ductwork, and how well the unit is matched to the space. The weather record belongs in that conversation, but it does not lead it.
Ductwork sized and routed for an older heating system does not automatically carry a modern central AC unit without adjustment. Half the homes in Parke County, Indiana were built in 1972 or earlier (2020-2024 ACS 5-year). A contractor installing central AC in stock of this age has to assess what the existing duct layout can actually deliver before the equipment selection matters at all. Runs that are too long, returns that are undersized, or trunk lines that branch wrong for cooling all show up on the job, and they shape the scope of the installation. The electrical service gets the same look, because what a new unit draws has to match what the panel can supply.
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. Inside, the air handler or furnace-mounted evaporator coil sits in a mechanical room, basement, or utility closet and is the indoor half of the system. Together these two units are what a contractor is placing when a new central AC goes in.
The refrigerant line set runs between the two units, typically along an exterior wall or through a utility chase, and the copper tubing carries refrigerant back and forth between inside and outside. A condensate drain line runs from the indoor coil to a floor drain or outdoors, and a thermostat goes on an interior wall where it reads the home's temperature and signals the system to run.
The drawing alongside shows the general layout of these components, and a licensed contractor determines exactly how each one fits the configuration of your house.

What happens on installation day in Parke 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.
Severe Weather Events in Parke County
Parke County's climate puts real demands on central AC equipment, and those demands are shaped by local conditions more than most homeowners expect. How often severe weather moves through an area affects how hard a system works, how it ages, and what a contractor installs to hold up over time.
