Takes about a minute. No obligation.
A contractor quoting central AC installation in Metcalfe County needs to account for what the local weather actually demands, and the record here lands at the low end of that range. 53 severe weather events were recorded in Metcalfe County, Kentucky between 2015 and 2024. At that rate, severe weather is an event in this county, not a standing condition, and it tells a contractor relatively little about why an old system gave out or what the replacement needs to survive. Sizing decisions and duct work quality carry more weight here than storm hardening. A system installed well and sized correctly for the house will spend most of its working life dealing with ordinary summer load, which is the problem worth solving.
Ductwork laid down for an older generation of equipment carries different dimensions, materials, and static pressure assumptions than a new central AC system is sized against. Half the homes in Metcalfe County, Kentucky were built in 1986 or earlier (2020-2024 ACS 5-year). A contractor pricing an installation here reads the existing duct runs before they price the unit, because what those runs can and cannot carry sets the scope. If the distribution system needs to be rebuilt or substantially modified, that work drives the job. The equipment selection comes after.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a pad outside the house and holds the compressor and condenser coil, which together handle the heat that gets pulled from inside. The indoor air handler or furnace lives in a utility space, basement, or closet, and it carries the evaporator coil where indoor air passes through before circulating back into the rooms.
The thermostat mounts on an interior wall and is the control point the household interacts with every day. A contractor also installs the refrigerant line set, a pair of copper lines that run between the indoor and outdoor units, along with a condensate drain line that carries moisture away from the evaporator coil.
The drawing shows a typical layout, and a licensed contractor determines what the configuration looks like in this specific 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 Metcalfe 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 Metcalfe County
Weather extremes put direct load on cooling equipment, shortening the gap between what a system was sized for and what it actually faces. How hard that pressure runs in Metcalfe County shapes what a contractor installs and how that equipment needs to be built to last.
