A contractor quoting central AC installation in Pulaski County has to treat sizing as a first-order problem, not an afterthought. 211 severe weather events were recorded in Pulaski County, Kentucky between 2015 and 2024. At that rate of severe weather, a system sized to a catalog average rather than to local conditions carries the wrong assumptions into every cooling season it runs. Ductwork sealing, equipment ratings, and the quality of the refrigerant charge all carry more weight in an area where the load swings hard and regularly than they would somewhere the air barely moves.
Ductwork sized and routed for a furnace runs differently than what a central AC system needs to move cooled air through the house. Half the homes in Pulaski County, Kentucky were built in 1986 or earlier (2020-2024 ACS 5-year). In the older half of the county's housing stock, that ductwork was laid out for heat, not cooling, and the electrical service was sized for what appliances drew at the time the house was built. A contractor installing central AC in houses from that era measures what is already there before pricing anything, because the duct layout and the panel both decide whether the install is straightforward or whether the house needs work before the unit goes in.
What Gets Installed With a New Central AC
The outdoor unit, or condenser, sits on a pad outside the house and holds the compressor and condenser coil. Inside, the air handler or furnace-based coil cabinet stands in a utility space, basement, or closet and carries the evaporator coil where the cooling happens. These two units are what a homeowner is buying.
A refrigerant line set runs between the two units, carrying refrigerant through insulated copper tubing that passes through the wall or floor. The thermostat mounts on an interior wall and gives the homeowner control over the whole system. A contractor also connects the system to the existing condensate drain line to carry away the moisture the evaporator coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house based on its construction and existing equipment.

What HVAC Installation Looks Like in Pulaski 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.
Licensing and Legal Requirements in Pulaski 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 Pulaski County
Weather patterns in Pulaski County put real load on cooling equipment, and how hard a system works over its life depends on what the local climate actually demands of it. Central AC installation sized and built for what this area sees is a different job than a generic install.
