A central AC compressor in this area sits dormant for most of the calendar year, then gets called on hard when summer heat finally arrives. Homes in Hettinger County, ND run cooling about two months a year, from July through August. After months off, contactors corrode, capacitors weaken, and the compressor itself has to start cold against whatever refrigerant pressure built up over winter. A contractor diagnosing a unit here checks those components first, because the first hot week of July is when latent faults surface, not after a long grinding season of daily cycling.
Half the homes in Hettinger County, North Dakota were built in 1964 or earlier (2020-2024 ACS 5-year). A house built that long ago was wired and ducted for something other than what sits in it today. When a contractor opens a central AC unit here, what they find behind the access panel often reflects that history directly: spliced refrigerant lines, ductwork that has been rerouted or resealed more than once, and connections that have been adapted rather than replaced. Parts for a system running in stock this old are not always current catalog items, and sourcing them shapes both the repair timeline and what the contractor recommends next.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and it carries the compressor and condenser coil. These are where a contractor starts when a system stops cooling. A failed compressor or a coil that has lost refrigerant will show up here before anywhere else.
Inside, the air handler holds the evaporator coil and the blower that moves conditioned air through the house. The refrigerant lines run between the two units, and the thermostat on the wall is what tells the whole system when to run. Wiring faults and sensor problems often trace back to the air handler or the thermostat.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply to your particular house.

What happens when a contractor comes out
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.
