Sizing central AC in Morgan County starts with what the climate has actually asked of equipment here, and that question has a real answer. 111 severe weather events were recorded in Morgan County, Kentucky between 2015 and 2024. At roughly the midpoint of counties nationwide, that record means severe weather is a genuine part of operating conditions, not a rarity, but also not the dominant explanation when a system underperforms. A contractor quoting an installation has to size for that load correctly from the start, because an undersized unit in a county with this kind of weather history runs harder than the equipment was rated to handle, and the shortfall shows up in the compressor before it shows up anywhere else.
Ductwork laid out for older equipment carries assumptions about airflow and routing that a new central AC system does not share. Half the homes in Morgan County, Kentucky were built in 1991 or earlier (2020-2024 ACS 5-year). A contractor installing a new system in stock like this opens walls and crawlspaces to find out whether what is there can be used, modified, or has to be rerouted entirely before the unit is ever priced. The electrical service gets the same check: what the house was wired for and what a new system draws are two separate questions, and the answer to the first one does not settle the second.
What Gets Installed With a New Central AC
The outdoor unit sits on a pad outside the house and holds the compressor and condenser coil, the two components that shed heat to the open air. Inside, the air handler or furnace with an evaporator coil mounts in a utility room, basement, or closet and is the piece that actually conditions the air moving through the home.
The thermostat goes on a central interior wall and is what the homeowner sets to control the whole system. A refrigerant line set runs between the indoor and outdoor units, and a condensate drain line carries moisture away from the evaporator coil to a floor drain or outside.
The drawing shows a typical layout, and a licensed contractor determines exactly what fits and where in your specific home.

What HVAC Installation Looks Like in Morgan 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.
