A contractor diagnosing a failed compressor here has to rule out deferred maintenance before blaming hours on the machine. Homes in Richland County, ND run cooling about two months a year, from July through August. The compressor, the condenser fan, and the contactor all sit idle through most of the calendar year, and components that stand cold and unused for long stretches fail in ways that look nothing like wear. Capacitors degrade on the shelf as readily as under load. A contractor who prices the repair without checking the full electrical side of the condensing unit will miss the actual problem.
Ductwork laid decades before the current unit arrived was sized and routed for whatever came first, and when a contractor opens the equipment to diagnose a fault, what they find inside reflects that history. Half the homes in Richland County, North Dakota were built in 1972 or earlier (2020-2024 ACS 5-year). A compressor or control board from a system that old may have no current replacement, which turns a repair call into a conversation about what the contractor could actually source and how long that takes. The age of the building is not the variable that determines the bill; the availability of parts for the system that ended up in it is.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house and holds the compressor and condenser coil, which together shed the heat the system pulls from inside. These are the first pieces a contractor looks at, because a failed compressor or a fouled coil will stop cooling entirely. The air handler or furnace cabinet inside the house holds the evaporator coil, where the actual heat absorption happens, and a refrigerant leak or frozen coil there shows up fast.
The expansion valve controls refrigerant flow between the two coils and is a common source of uneven cooling or a system that short-cycles. The blower fan inside the air handler pushes conditioned air into the duct system, and a failing motor or capacitor there can mimic what looks like a refrigerant problem. Contractors also check the electrical components in both cabinets, including capacitors and contactors, before going deeper.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which of these components applies to the specific setup in your 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.
Licensing and Legal Requirements in Richland County, North Dakota
North Dakota requires a contractor licence once the cost, value or price of a job exceeds four thousand dollars, and an unlicensed contractor may not bring a claim or a lawsuit in a North Dakota court over the work.
Severe Weather Events in Richland County
Weather in Richland County puts real stress on central AC systems, and that stress accumulates over time. A unit that runs hard through rough conditions is more likely to need repair, which makes local weather history a relevant part of understanding local equipment wear.
