Takes about a minute. No obligation.
The compressor in a central AC unit starts and stops every time the house calls for cooling, and the contactor closes that circuit each time. Homes in Pawnee County, KS run cooling about four months a year, from June through September. By September, a compressor that was already marginal has run through a full season of that cycling, and a contractor diagnosing a fault here pulls the contactor and checks compressor amp draw before chasing anything else. Wear concentrates in those parts because the load does.
Ductwork in a house outlasts the equipment it was built around, and the central AC unit running in it now is rarely the first one and may not share a parts family with what a supplier stocks today. Half the homes in Pawnee County, Kansas were built in 1956 or earlier (2020-2024 ACS 5-year). When a contractor opens a system in housing like this, what determines the repair is whether the capacitor, contactor, or control board the unit takes is still being made, and if not, whether a compatible substitute exists. That question drives both the timeline and the bill.
The Parts of a Central AC a Contractor Checks During a Repair
The outdoor condenser unit sits outside the house, usually on a concrete pad along a wall, and houses the compressor and condenser coil. These are the pieces a contractor goes to first when the system runs but does not cool, or when it makes unusual noise. Inside, the air handler holds the evaporator coil and the blower that moves air through your home.
The refrigerant lines run between the two units, carrying the working fluid that makes the whole exchange possible. A metering device, often a small expansion valve near the indoor coil, controls how that fluid moves. The thermostat on your wall is the last piece a contractor checks, since a wiring fault or a failed sensor there can mimic problems that appear to belong deeper in the system.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which parts apply to your specific house and situation.

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.
