A contractor quoting a central AC install in Stark County has to account for what the equipment will actually run against here. 131 severe weather events were recorded in Stark County, Ohio between 2015 and 2024. Severe weather at that rate is a standing condition, and it shapes how a system gets sized and specified before a single component is ordered. A unit matched to a milder load profile will be pushed harder than its design assumed, and that shows up in how long it lasts and how often it needs attention. Contractors who work this area build that into the quote from the start.
Ductwork laid down for a furnace was sized and routed for one direction of airflow, and fitting a central AC system to it means a contractor has to assess whether it will carry the new load before anything else gets priced. Half the homes in Stark County, Ohio were built in 1966 or earlier (2020-2024 ACS 5-year). That building era predates residential central air as a standard feature, so the duct runs in a substantial share of this county's homes were never designed with cooling in mind. The electrical panel gets the same scrutiny: what a new condensing unit draws has to match what the service can deliver. Those two assessments, ductwork and electrical, are where the actual variation in an installation job lives.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad along a side or rear wall, and holds 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. These two pieces are what a contractor brings and sets in place.
A copper refrigerant line set runs between the outdoor and indoor units, connecting the two and traveling through a small penetration in the wall. The thermostat goes on an interior wall where the homeowner can reach it and serves as the control point for the whole system.
The drawing shows a typical layout, and a licensed contractor determines what configuration fits the specifics of your house.

What the Installation 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.
