A contractor quoting a central AC installation in Menifee County has to settle the sizing question before anything else, and the answer here turns on the building's load characteristics rather than on what the sky throws at it. 67 severe weather events were recorded in Menifee County, Kentucky between 2015 and 2024. At roughly the national median, that record puts severe weather in the occasional category for this area. Age of the structure, duct condition, and whether a previous system was sized correctly are the variables that drive an install spec here, and a contractor who treats this county as a high-weather-load site will oversize the equipment and leave the homeowner with a system that short-cycles for years.
Ductwork laid down for an older system was routed around the house that existed then, not the one a new central AC unit has to condition efficiently. Half the homes in Menifee County, Kentucky were built in 1989 or earlier (2020-2024 ACS 5-year). That gap between what the ducts were designed to carry and what a new system needs to push through them is where a contractor's assessment spends the most time. Leaks, undersized runs, and register placement that made sense for older equipment can all undercut a new unit's performance before it runs its first cycle. The electrical panel gets the same scrutiny, because the draw a modern central AC puts on a service entrance may not match what the original wiring anticipated.
What Gets Installed With a New Central AC
The outdoor unit is the piece most homeowners recognize first. It sits on a concrete pad outside the house and holds the compressor and condenser coil. Inside, the air handler or furnace with an evaporator coil mounts in a utility closet, basement, or attic and is the point where cooled air enters the duct system.
The refrigerant line set runs between the two units, connecting the outdoor pad to the indoor cabinet through a wall or crawl space. A thermostat goes on an interior wall and is the control point the homeowner uses to set temperatures and run schedules.
The drawing beside this text shows the general layout of a central AC system, and a licensed contractor determines exactly how each piece applies to your home.

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 Menifee 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.
Severe Weather Events in Menifee County
Weather puts real hours on HVAC equipment. Sizing and installing a central AC system right means accounting for what the local climate actually demands, and that varies from one Kentucky county to the next.
