A contractor quoting a central AC installation in Paulding County starts from what the local climate actually demands, and the record here is modest. 49 severe weather events were recorded in Paulding County, Ohio between 2015 and 2024. At that rate, severe weather is something a system encounters from time to time, not a grinding seasonal load. That means sizing and installation quality carry more weight in how a system performs and lasts than weather exposure does. A contractor who cuts corners on refrigerant charge, duct sealing, or equipment placement will produce a system that underperforms regardless of how mild the summers run.
Ductwork laid down for a furnace and never touched since does not always move conditioned air the way a central AC system needs it to. Half the homes in Paulding County, Ohio were built in 1971 or earlier (2020-2024 ACS 5-year). That age of construction puts a contractor sizing a new system in a position where the ducts have to be walked and measured before the equipment can be matched, because the existing layout may not distribute cooling evenly across the house. What the electrical service can carry is the second question. A panel installed for the demands of an older era may fall short of what a new unit draws, and that gap gets priced before anything else is ordered.
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, which together handle the system's heaviest work. Inside, the air handler or furnace cabinet stands in a utility space, basement, or closet and moves air through the home. These two units are what a new installation puts in place.
A refrigerant line set runs between the outdoor and indoor units, carrying the refrigerant that links the two sides of the system. A thermostat mounts on an interior wall and gives the homeowner direct control over when the system runs and at what temperature.
The drawing shows a typical layout, and a licensed contractor determines what applies to the specific configuration of your house.

What HVAC Installation Looks Like in Paulding 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.
