Takes about a minute. No obligation.
Central AC in Platte County spends the vast majority of the year sitting idle. Homes in Platte County, WY run cooling in a single month of the year, July. Condensers and contactors that cycle hard through a single compressed push every year accumulate wear in bursts, and the long off-season does nothing to recover a component that was already marginal going in. A contractor opening a unit here checks the compressor and contactor for the kind of fatigue that one concentrated annual load produces, rather than the gradual degradation that spreads across a longer season. A system that looked fine when it shut down in August can present with a seized compressor the following July.
Ductwork in a house this old has been carrying air for long enough that what a contractor finds behind the grille can range from sound to compromised, and the condition of it shapes how a repair on the central AC unit actually goes. Half the homes in Platte County, Wyoming were built in 1976 or earlier (2020-2024 ACS 5-year). A system serving a house from that era of construction has run through a long string of seasons, and when a technician opens it up, the parts inside may be from a generation of equipment whose replacement components are no longer in common supply. That gap between what the unit needs and what a distributor still stocks is what determines whether a repair is finished quickly or requires sourcing work before the house cools down again.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad against an exterior wall, and it carries the compressor and the condenser coil. Both are common failure points. A compressor that has seized or a coil that has lost refrigerant will stop the whole system cold, so a contractor starts here.
Inside, the air handler holds the evaporator coil and the blower fan, typically in a utility closet, basement, or attic. The evaporator coil can ice over or leak, and the blower motor can wear out or seize. The expansion valve and the refrigerant lines that run between the two units also get checked when the system is underperforming or not cooling at all.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply to your particular house and situation.

What Repair Work Looks Like in Platte County
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.
