A contractor quoting a central AC install in Burke County has an unusual starting point. Homes in Burke County, ND have essentially no cooling season — no month of the year is warm enough to call for it. A compressor sitting in a home here has logged essentially no runtime on cooling cycles, which means wear on the condenser fan, the contactor, and the compressor itself tells you almost nothing about how the system has been used. What ages the equipment is calendar time and storage conditions, not load cycles. The installer's sizing work still matters, because a system put in poorly will show those faults the first summer it is asked to run.
Ductwork in a house built for a North Dakota furnace was laid out to push warm air, not to circulate cooled air across a full living space, and the two jobs make different demands on the same passages. Half the homes in Burke County, North Dakota were built in 1969 or earlier (2020-2024 ACS 5-year). A contractor sizing a new central AC system here has to open up and trace what is actually in place before the quote means anything, because trunk lines, branch runs, and register placement that worked for heat may leave whole rooms underserved by cooling. The electrical service is a separate question that also gets checked before equipment is specified.
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 the coil that releases heat to the outside air. The indoor air handler or furnace sits inside, most often in a basement, closet, or utility room, and moves conditioned air through the home.
The evaporator coil mounts directly above or inside the air handler and is the point where the refrigerant line set connects the two main units. That line set, a pair of copper tubes, runs between the outdoor and indoor units and carries refrigerant back and forth. A thermostat goes on an interior wall and gives the homeowner control over the whole system.
The drawing shows the general layout of these components, and a licensed contractor determines exactly how each one applies to 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.
