Homes in Griggs County, ND run cooling in a single month of the year, July. A compressor that starts once a year after months of standing still is the first thing a contractor checks when a call comes in: the contactor contacts corrode, capacitors drain slowly while the unit sits, and refrigerant-side seals that never see pressure for most of the year are where leaks tend to open. The condenser fan and the electrical connections around it get the same attention, because a single short season of hard running followed by a long idle is its own failure pattern.
Ductwork installed for one system and pressed into service for several successive ones accumulates a particular kind of problem: gaps, sags, and restrictions that developed over decades of adaptation rather than from any single failure. Half the homes in Griggs County, North Dakota were built in 1958 or earlier (2020-2024 ACS 5-year). A contractor pulling apart a central AC repair here finds that the rated performance of the equipment and what the duct system will actually deliver are two different numbers. Sealing a refrigerant leak or swapping a contactor is straightforward; confirming the duct conditions are not cutting the repaired unit's output short takes longer and changes what goes on the repair ticket.
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 condenser coil. These are the pieces a contractor reaches first when the system stops cooling, because a failed compressor or a fouled coil accounts for a large share of repair calls. The air handler or furnace inside the house holds the evaporator coil, which is where the other half of the cooling work happens.
The refrigerant lines run between the two units and the expansion valve controls how refrigerant moves through the coil. The blower fan inside the air handler pushes conditioned air into the duct system, and the capacitors and contactors in the outdoor cabinet start and run the compressor motor. Any of these can be the source of a problem, so a contractor works through them until the fault is found.

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.
