Takes about a minute. No obligation.
A contractor quoting a central AC install in Pike County has to size the system for a climate that delivers genuine punishment, not a mild shoulder-season place where any box will do. 164 severe weather events were recorded in Pike County, Kentucky between 2015 and 2024. At roughly that rate, severe weather is a recurring feature of life here, and a unit undersized or poorly sealed will feel it. Duct work, refrigerant line routing, and the quality of the electrical connections all carry more of the long-term performance burden than the equipment brand does.
Ductwork laid in for an older heating system was sized, routed, and sealed for different equipment. Half the homes in Pike County, Kentucky were built in 1985 or earlier (2020-2024 ACS 5-year). A house from that period often has supply and return runs that a contractor has to evaluate before any equipment decision gets made, because what will and will not carry a modern central AC load is specific to how that house was built. The electrical service carries the same question. A contractor opening up the utility space in a house like this is looking at infrastructure that predates current load requirements, and what they find there shapes the scope before any unit gets ordered.
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. These two units are the core of what a contractor brings to the job.
A refrigerant line set runs between the two units, connecting them through the wall or floor. A programmable thermostat mounts on an interior wall and gives the homeowner control over the whole system. The condensate drain line runs from the indoor coil to a nearby drain to carry away moisture pulled from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the configuration of your home.

What happens once a Pike County contractor takes the job
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 Rules for HVAC Work in Pike 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 Pike County
Weather puts a measurable load on cooling equipment, and that load is specific to where a system runs. A central AC unit installed in Pike County works against the local climate year after year, so what the county's weather record looks like matters when sizing and installing equipment here.
