A contractor quoting a central AC installation in Van Buren County is not sizing against a county that batters its equipment season after season. 22 severe weather events were recorded in Van Buren County, Tennessee between 2015 and 2024. At that rate, severe weather is an occasional event rather than a standing condition, and the variables that drive a proper installation here are the structure's cooling load, duct layout, and the quality of the work itself. A system that fails in this county most likely failed because of age or a poor original install, and the contractor's job on a new system is to get those fundamentals right.
Ductwork laid for one generation of equipment does not automatically carry the next. Half the homes in Van Buren County, Tennessee were built in 1978 or earlier (2020-2024 ACS 5-year). A contractor installing central AC in a house from that era has to assess whether the existing runs, returns, and trunk lines move enough air for a modern system before the unit itself ever gets priced. If they do not, resizing or rerouting duct is part of the job. The electrical service gets the same look, since load requirements have shifted since the house was wired.
What a Central AC System Includes
The indoor air handler sits inside the house, most often in a utility closet, attic, or basement, and it pulls warm air from the living space across the evaporator coil. The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil. Together, these two units are the core of what a contractor installs.
The refrigerant line set runs between the indoor and outdoor units, carrying refrigerant through copper tubing that connects the two sides of the system. A thermostat mounts on an interior wall and serves as the control point for the whole system, telling it when to run and at what target temperature.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions of this house.

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.
