The compressor in a central AC unit here carries a concentrated but brief load each year. Homes in Burleigh County, ND run cooling in a single month of the year, July. When a contractor opens a system to diagnose a fault, the contacts on the contactor, the capacitor, and the compressor windings show wear that accumulated across many summers of stop-start cycling, not from running hard through a long season. A short season means faults often sit unnoticed through fall, winter, and spring, then surface on the first hot day of July when demand spikes. That pattern pushes a contractor toward age-related component failure as the first thing to confirm, before chasing refrigerant charge or airflow problems that a longer-running system might develop mid-season.
Ductwork sized and fitted for an earlier generation of equipment is what a repair job here often starts with, and what the opened unit contains tends to match that history. Half the homes in Burleigh County, North Dakota were built in 1988 or earlier (2020-2024 ACS 5-year). A compressor or control board from a system installed to serve housing that old may predate current parts catalogs, which means a contractor confirming whether replacement parts are still made is a real step in the diagnosis, not a formality. What they find inside the cabinet determines whether the repair is straightforward or whether the job becomes a conversation about what is still available.
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 carries the compressor and the condenser coil. These are the parts a contractor reaches first when a system stops cooling, because a failed compressor or a fouled coil shows up fast and explains most complete failures.
Inside, the air handler or furnace cabinet holds the evaporator coil and the blower. The evaporator coil is where the refrigerant does its work, and a refrigerant leak or a frozen coil points straight back to it. The blower moves conditioned air into the duct system, and a failed blower motor means no airflow even when everything else is working.
The drawing shows the typical layout of these components, and a licensed contractor determines which of them applies to the specific system and setup in your house.

What a Repair Visit 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.
