A contractor quoting a central AC install in Buckingham County is not working from a generic load calculation. 136 severe weather events were recorded in Buckingham County, Virginia between 2015 and 2024. At that rate, severe weather is a standing condition in this area, and it shapes what equipment gets specified and how the install is executed. A system undersized or poorly anchored for this environment will be working against its own limits from the first season. What a licensed contractor pins down before they quote is how the house and the site sit inside that local demand.
Ductwork laid for an older system carries assumptions about airflow, return placement, and trunk sizing that a new central AC unit will test immediately. Half the homes in Buckingham County, Virginia were built in 1990 or earlier (2020-2024 ACS 5-year). A contractor quoting an installation here opens crawlspaces and checks what the existing duct network was actually built for before any equipment gets priced, because a system matched to the wrong ductwork will underperform regardless of its efficiency rating. The electrical service gets the same look: what a modern condenser draws has to land somewhere, and the panel has to support it.
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 houses the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil lives in a utility closet, basement, or attic and is the indoor half of the system. Together these two units form the core of what a contractor places and connects.
The refrigerant line set runs between the indoor and outdoor units, carrying refrigerant through insulated copper tubing routed along the exterior or through the wall. The thermostat goes on an interior wall and gives the homeowner control over the whole system. A condensate drain line also gets routed from the indoor coil to a suitable discharge point.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece is positioned and routed in your house.

What happens on installation day
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.

Severe Weather Events in Buckingham County
Weather puts direct pressure on heating and cooling equipment: temperature swings, humidity loads, and storm activity all affect how hard a system has to work and how long it lasts. What that workload looks like in Buckingham County shapes what a contractor installs and how they size it.
