Sizing a central AC unit for Burleigh County starts with understanding exactly how little the compressor is asked to do. Homes in Burleigh County, ND run cooling in a single month of the year, July. The contactor, the condenser fan, and the refrigerant circuit spend most of the calendar standing still, and components that sit can develop faults just as readily as ones that wear from heavy use. A contractor quoting an installation here has to account for that idle period in how they size and commission the equipment, because a system that starts cold after months off has no margin for an undersized coil or a loose connection.
Ductwork sized for an older system does not automatically carry a new central AC unit without a contractor checking it first. Half the homes in Burleigh County, North Dakota were built in 1988 or earlier (2020-2024 ACS 5-year). That means a substantial share of houses here have duct layouts designed around equipment with different airflow demands than what a new installation requires. A contractor will open registers, check trunk dimensions, and assess whether the existing runs can deliver what the new unit moves before the equipment is ever priced. If the ductwork falls short, it changes the scope of the job.
What Gets Installed With a New Central AC
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level beside the foundation, and it holds the compressor and the condenser coil. Inside, the air handler or furnace cabinet stands in a utility room, basement, or attic and contains the evaporator coil along with the blower that moves air through the house.
A refrigerant line set runs between the two units, carrying refrigerant through insulated copper tubing that a contractor routes along the exterior wall or through a small penetration. A condensate drain line and a low-voltage thermostat wire also connect to the indoor cabinet, and a programmable thermostat mounts on an interior wall where the homeowner sets the temperature.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the specific construction of your home.

What the installation looks like on your end
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.
