A contractor quoting central AC installation in Geauga County has to size the system for what the area actually asks of it, not for a moderate baseline. 142 severe weather events were recorded in Geauga County, Ohio between 2015 and 2024. At that rate, severe weather is part of normal operating life for any equipment here, and a unit undersized or poorly sealed at install will feel that load early. Contractors who work this county factor it into equipment selection and duct layout before the job starts.
Ductwork laid down for the original heating setup in a house this old was not designed around the airflow demands of modern central AC. A contractor quoting an installation here has to assess whether those existing runs can carry the new system before the equipment selection means much. Half the homes in Geauga County, Ohio were built in 1977 or earlier (2020-2024 ACS 5-year). That puts the duct layout at the front of the job, not the back, because undersized or poorly routed ductwork forces either a full re-run or a unit selection built around what the house will tolerate rather than what the house needs.
What a Central AC Installation Covers
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, the parts that shed heat to the outside air. Inside, the air handler or furnace-mounted evaporator coil lives in a utility space, basement, or closet and is the cold surface that pulls heat out of your home's air.
The refrigerant line set runs between those two units, a pair of copper lines that a contractor routes through walls or along the exterior to connect them. A disconnect box mounts near the outdoor unit and a new thermostat goes on an interior wall to give you control over the whole system.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house.

What HVAC Installation Looks Like in Geauga 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.
