A contractor quoting a central AC repair in Walsh County has to establish what the compressor has already been through before pricing a fix. Homes in Walsh County, ND run cooling in a single month of the year, July. Compressed into a single month, the full seasonal load lands on the compressor, the condenser fan, and the contactor all at once, with no gradual ramp to surface a developing fault early. Parts that are marginal going into July fail inside it. That means a contractor opening a unit here checks the contactor for pitting and the capacitor for swell before concluding the compressor itself is the problem, because a worn contactor can take the compressor with it.
Ductwork in houses this old has had a long time to accumulate debris, pest intrusion, and degraded insulation, and a repair call is often where that history first gets examined. Half the homes in Walsh County, North Dakota were built in 1971 or earlier (2020-2024 ACS 5-year). A contractor opening up a central AC system here checks not just the equipment but what the ducts feeding it actually contain, because blockage and leakage in older ductwork can produce symptoms that look exactly like a failing unit. What they find inside changes the scope of the repair.
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 where a contractor starts. A failed compressor, a refrigerant leak at the coil, or a seized condenser fan motor are the most common reasons a system stops cooling.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower motor. The evaporator coil is where a frozen coil or a refrigerant shortage first shows up, and a failing blower motor explains poor airflow even when the outdoor unit runs fine. The two sides connect through refrigerant lines that run between them, and those lines are also on a contractor's checklist.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply to your specific house and situation.

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.
