Takes about a minute. No obligation.
A contractor quoting a repair on a central AC unit here needs to know how lightly this equipment has been used. Homes in Pembina County, ND run cooling in a single month of the year, July. With a cooling load that compressed, the compressor logs relatively few starting cycles each year, but those cycles are unspread across a long idle period where small faults go unfound. The contractor checking a failed contactor or a seized compressor in July is often looking at a part that degraded slowly across several off-seasons and showed its failure only when the first real heat demand landed.
Ductwork and wiring in a house tell you about the building. The parts inside a failed compressor or control board tell you whether the repair is even possible. Half the homes in Pembina County, North Dakota were built in 1969 or earlier (2020-2024 ACS 5-year). A system running in stock that old has almost certainly been swapped in since the original build, and what the opened unit turns out to need determines the job more than anything else on the property. Some of those components are still made; some require a contractor to source carefully or price a replacement instead.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and it carries the compressor and condenser coil. These are the pieces a contractor reaches first when the system is not cooling, because a failed compressor or a fouled coil are common sources of the problem. The indoor air handler or furnace coil sits inside, typically in a closet, attic, or basement, and holds the evaporator coil where the actual cooling happens.
The refrigerant lines run between the two units and carry the charge that makes the whole exchange possible. A contractor checks these for leaks when pressures are off. The thermostat, mounted on an interior wall, controls the call for cooling and is a frequent culprit when a system runs poorly or refuses to start at all.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to your specific house and setup.

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.
