A central AC compressor that sits unused season after season develops its own failure modes: seized parts, degraded lubricant, contactor corrosion. Homes in Rolette County, ND have essentially no cooling season — no month of the year is warm enough to call for it. When a unit fails on the first genuinely warm day, a contractor has to separate age and storage damage from any mechanical fault before settling on a repair scope. The refrigerant circuit and the contactor get checked before the compressor itself is condemned, because idle deterioration can look like a hard failure and the repair bills are not the same.
Duct runs in much of this county were put in for equipment that is long gone, and what has accumulated inside them shapes how a repair goes as much as whatever brought the contractor out. Half the homes in Rolette County, North Dakota were built in 1980 or earlier (2020-2024 ACS 5-year). A unit that failed because of restricted airflow sends a contractor into ductwork that was never sized for what runs through it now, and a cracked heat exchanger or a seized compressor may be a symptom of that mismatch rather than the starting point of the problem. The failed part gets replaced; whether the repair holds depends on what the ductwork is doing to the system it feeds.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad at the side or rear, and it is where the system sheds heat. The compressor lives inside that cabinet and is the part contractors go to first when a system has stopped cooling or is running but doing nothing.
Inside the house, the air handler or furnace cabinet holds the evaporator coil, which is where the air actually gets cold, and the blower that pushes that air through the home. The refrigerant lines running between the two units and the expansion valve that meters refrigerant flow are the other points a contractor traces when the coil and compressor check out.
The drawing shows a typical central AC layout, and a licensed contractor determines which components apply to your specific system and what each one needs.

What Happens When the Contractor Arrives
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.
