Sizing a central AC system for this county starts with what the equipment will actually be asked to carry through a typical season. 105 severe weather events were recorded in Coshocton County, Ohio between 2015 and 2024. At that rate, severe weather is a recurring part of the load a system runs against, present enough that a contractor has to account for it when selecting equipment capacity and specifying the quality of the installation, but not so relentless that it overrides every other factor. A unit that is slightly undersized or installed with loose connections will show that weakness here before it would in a quieter area.
Ductwork laid out for a furnace and a gravity system was never drawn with central cooling in mind. Half the homes in Coshocton County, Ohio were built in 1967 or earlier (2020-2024 ACS 5-year). That gap between what the ducts were built to do and what a new central AC unit will ask of them is where a contractor's site assessment concentrates. Electrical service follows: a panel from that era may have been updated, or it may not, and the unit going in has a specific draw the existing service either meets or does not. The ductwork and the panel together decide the scope before the equipment choice does.
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 two components that do the heaviest work in the system. Inside, the air handler or furnace cabinet stands in a utility space, basement, or closet and pairs with an evaporator coil mounted directly above it.
The refrigerant line set runs between those two cabinets, carrying the fluid that ties the indoor and outdoor sides together. A thermostat goes on an interior wall and gives the homeowner control over the whole system. A new disconnect box and condensate drain line are also part of what a contractor puts in place.
The drawing beside this text shows a typical layout, and a licensed contractor determines exactly what applies to your house.

What the installation actually 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.
Licensing and Legal Requirements in Coshocton County, Ohio
An Ohio home construction services contract must include a copy of the supplier's certificate of insurance showing general liability coverage of not less than two hundred fifty thousand dollars.
In Ohio a home construction service means the construction of a residential building, including the repair, improvement, remodel or renovation of an existing structure, and does not include construction on a structure containing four or more dwelling units except for work on an individual dwelling unit within it.
A home construction service supplier in Ohio is defined as a person who contracts with an owner to provide home construction services for compensation and who maintains a general liability insurance policy of not less than two hundred fifty thousand dollars.
The Ohio construction industry licensing board issues state licenses to individuals as heating, ventilating and air conditioning contractors, refrigeration contractors, electrical contractors, plumbing contractors and hydronics contractors.
An Ohio board of county commissioners may accept a valid and unexpired Chapter 4740 license held by a heating, ventilating and air conditioning contractor toward its own licensing requirements for work on one-, two-, or three-family dwelling houses.
An Ohio board of county commissioners may adopt rules licensing heating, ventilating and air conditioning contractors who are not required to hold a state license under Chapter 4740.
In Ohio municipal law a specialty contractor includes heating, ventilating and air conditioning contractors, refrigeration contractors, electrical contractors, plumbing contractors and hydronics contractors.
