Compressors that sit idle for most of the year develop faults that stay hidden until the load arrives. Homes in Bowman County, ND run cooling about two months a year, from July through August. A contactor that started sticking in September will not announce itself until July, and by then the system has been sitting with that problem through a long off-season. Contractors diagnosing central AC here check the contactor, capacitor, and refrigerant charge before anything else, because those are the parts that fail quietly during extended idle periods and show up hard on the first call of summer.
Much of what a central AC system runs through in Bowman County has been through several service cycles already. Half the homes in Bowman County, North Dakota were built in 1972 or earlier (2020-2024 ACS 5-year). Ductwork in houses that old has typically been sealed, re-routed, or left as-is through multiple equipment changes, and the system running in it now is not what the house was built around. When a contractor opens a unit here, what they find reflects that layered history: a capacitor that has been asked to start the same compressor through years of summer heat, a contactor worn from accumulated cycling, refrigerant lines that may have been accessed and recharged more than once. Parts availability for older equipment varies, and that is what determines whether a repair is a same-week fix or a longer conversation about what is still manufactured.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along a side or rear wall, and it is where heat gets released to the outside air. The compressor lives inside that cabinet and is one of the first things a contractor examines when a system stops cooling. A failed compressor, a seized fan motor, or a refrigerant leak all trace back to that outdoor unit.
Inside the house, the air handler or furnace-mounted evaporator coil sits in a mechanical room, basement, or utility closet, drawing warm air across a coil to pull heat out of it. The refrigerant line set runs between the two units, and the thermostat on the wall tells the whole system when to run. Problems with the indoor coil, the refrigerant lines, or the thermostat each produce symptoms a contractor reads before touching anything.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply to your particular house and situation.

What Happens When the 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.
