Sizing a central AC system for Emmons County starts with what the compressor is actually asked to do here. Homes in Emmons County, ND run cooling about two months a year, from July through August. The compressor, condenser fan, and contactor stay off for most of the calendar, and long idle periods let refrigerant seals dry, electrical contacts oxidize, and small faults go unnoticed. A contractor quoting an install here accounts for that pattern: the system needs to start reliably after months of sitting, not just run well once it is already cycling. That shifts attention toward equipment quality and installation detail over raw capacity.
Ductwork and electrical service put in for a furnace and window units were not designed around a central AC load, and in Emmons County much of the housing was never updated to close that gap. Half the homes in Emmons County, North Dakota were built in 1965 or earlier (2020-2024 ACS 5-year). A contractor quoting a new system here sizes the unit to what the house actually needs, then works out whether the existing ducts will carry it and whether the service panel will support what the new equipment draws. Those two questions decide the scope of the job far more than the equipment selection does.
What a Central AC System Includes
The outdoor condenser unit sits on a pad beside the house and holds the compressor and condenser coil, which are the parts that shed heat to the outside air. Inside, the air handler or furnace blower sits in a utility space, basement, or closet and pushes conditioned air through the home. Together these two units form the core of what a contractor installs.
A refrigerant line set runs between the indoor and outdoor units, carrying refrigerant back and forth through insulated copper tubing. The thermostat mounts on an interior wall and is the control point for the whole system, telling the equipment when to run and when to stop.

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.
