A contractor sizing or installing central AC in Campbell County has to account for what the local climate actually demands, and the weather record here is worth understanding clearly. 79 severe weather events were recorded in Campbell County, Kentucky between 2015 and 2024. At roughly the national median, that rate puts severe weather in the category of something a system encounters across its life, but not something it fights constantly. That distinction changes what a contractor focuses on at installation: getting the sizing and refrigerant charge right for a temperate load profile, and sealing the ductwork so the system runs efficiently on ordinary summer days. A unit installed correctly here should not be fighting the climate so much as running steadily through it, which puts the long-term burden on the quality of the original work rather than on what the sky does.
Ductwork laid down for an older forced-air system was sized and routed for that system, and a new central AC unit has to run on whatever is there. Half the homes in Campbell County, Kentucky were built in 1972 or earlier (2020-2024 ACS 5-year). A contractor putting in a new system in a house like that has to look at what the existing ducts can actually move, where they run, and whether the electrical service will carry the load. If the ducts are undersized or the panel is inadequate, those are the jobs that shape the installation, and the equipment selection follows from them rather than driving them.
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 cabinet lives in a utility space, a basement, or an attic and contains the evaporator coil that absorbs heat from the air moving through your home.
A refrigerant line set runs between the indoor and outdoor units, carrying refrigerant back and forth through insulated copper tubing. The thermostat mounts on an interior wall and is the control point the homeowner actually touches, telling the system when to run and when to stop.
The drawing shows the general layout of a central AC system, and a licensed contractor determines exactly what applies to your house and how each piece gets positioned within it.

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 Campbell County, Kentucky
Kentucky requires a licence to practise heating, ventilation and air conditioning contracting: a person may not do the work unless they have met the state licensing requirements.
