A contractor quoting a central AC install in Fulton County has to work out what the existing system was actually up against before it failed. 53 severe weather events were recorded in Fulton County, Indiana between 2015 and 2024. At that rate, severe weather is an occasional event here, not a standing condition. A system that gave out is far more likely to have run too long on an undersized or poorly installed original unit than to have been worn down by storm load. That means the sizing conversation and the quality of the new install carry more weight than any weather allowance, and a contractor who skips that diagnosis is guessing at the spec.
Ductwork laid down for a furnace and left mostly untouched carries a different geometry than what a central AC system wants: tighter in the wrong places, short on return paths, and sized around moving warm air up rather than cool air through every room. Half the homes in Fulton County, Indiana were built in 1966 or earlier (2020-2024 ACS 5-year). A contractor installing central AC in a house of that vintage has to assess whether the existing duct runs can handle the system before the equipment question even opens. Electrical service is the same story: older panels often lack the capacity a modern condenser requires, and that gap shows up in the quote, not after the install.
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, the two components that do the heaviest work in the system. Inside, the air handler or furnace-mounted evaporator coil lives in a utility space, basement, or closet, and this is where the system pulls heat out of the indoor air before sending cooled air back through the house.
A refrigerant line set runs between the outdoor unit and the indoor coil, connecting the two halves of the system through the wall or floor. The thermostat mounts on an interior wall and gives the homeowner control over when the system runs and at what target temperature.
The drawing shows the general layout of a central AC system, and a licensed contractor determines exactly how each piece fits the specific conditions of your home.

What happens when the contractor comes out
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 Fulton County
Weather puts real demands on cooling equipment, and those demands vary by location. A system sized and installed for what Fulton County actually sees will hold up better and run more efficiently than one specced to a generic standard.
