Takes about a minute. No obligation.
A central AC compressor in this county spends its entire life on standby. Homes in Benson County, ND have essentially no cooling season — no month of the year is warm enough to call for it. Seals dry out when they go months without cycling, contactor points corrode without the current to keep them clean, and capacitors lose their charge tolerance sitting unused. The failure a contractor finds on the first hot call of summer is almost always a storage failure, and the diagnostic starts there.
Ductwork that has served successive systems accumulates a repair history that shows up the moment a contractor opens the equipment. Half the homes in Benson County, North Dakota were built in 1972 or earlier (2020-2024 ACS 5-year). That depth of turnover means the unit a contractor is working on is unlikely to be original to the house, but the parts it takes may still be scarce or out of production entirely. What a contractor finds inside determines whether the repair is a straightforward swap or a search for a compatible alternative, and that answer comes from the opened system, not from the address.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it holds the compressor and condenser coil. These are the pieces a contractor reaches first when the system stops cooling, because a failed compressor or a fouled coil will shut down the whole system. The indoor air handler or furnace cabinet, tucked in a basement, closet, or attic, holds the evaporator coil, which is another common point of failure when cooling drops off or ice starts to form.
The refrigerant lines run between those two units, and a leak anywhere along them pulls the whole system out of balance. The expansion valve and the electrical controls, including the capacitors and contactors inside the outdoor cabinet, are smaller components that a contractor checks closely because they fail quietly and are often the actual cause when the larger parts test out fine.
The drawing shows a typical layout, and a licensed contractor determines which components and access points apply to this particular house.

What the repair visit 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.
