A contractor quoting central AC installation in Webster County has to size the system for the local load, and part of that picture is how often the weather here actually pushes equipment hard. 79 severe weather events were recorded in Webster County, Kentucky between 2015 and 2024. At that rate, severe weather sits in the background of a system's life rather than at the center of it. Age, installation quality, and duct condition are what drive how a system performs here. A contractor who blames weather for a failing unit in this county is reaching for something the record does not support.
Ductwork laid in for an older system answers to different demands than a new central AC unit makes. Half the homes in Webster County, Kentucky were built in 1977 or earlier (2020-2024 ACS 5-year). What that gap in years means for an installation job is that the existing duct runs may not move enough air, may not reach where the new equipment needs them to, and may need to be brought up before the unit itself is ever sized. The electrical service is a separate question, but the ductwork is where the scope of the job gets settled.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and holds the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil sits in a utility space, basement, or closet and is the indoor half of the system. Together these two units are what a Central AC installation puts in place.
The refrigerant line set runs between the indoor and outdoor units, typically along an exterior wall, and connects the two halves so they work as one system. A thermostat goes on an interior wall where it reads the home's temperature and tells the system when to run.
The drawing shows a typical layout, and a licensed contractor determines what fits this house and its existing setup.

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.
