Central AC in Park County spends its life waiting. Homes in Park County, CO have essentially no cooling season — no month of the year is warm enough to call for it. A compressor that never runs does not wear out the way a hard-used one does, but it dries out, seizes up, and loses refrigerant through seals that were never cycled. When a contractor opens the system, the contactor and capacitor tend to degrade from age and temperature swings rather than from the start-stop cycles a working season would produce. A fault that sat unnoticed all winter surfaces the first day someone switches the system on, which is the day the service call comes in.
Ductwork in a house this old has already adapted to more than one generation of equipment. Half the homes in Park County, Colorado were built in 1992 or earlier (2020-2024 ACS 5-year). That history matters for repair work specifically because the system now running in a house like this may take parts that are increasingly hard to source, and what a contractor finds once the unit is open can change the scope of the job entirely. A refrigerant seal, a control board, a compressor valve: availability on parts for systems installed into older stock is the variable that shapes both the repair timeline and what the contractor recommends.
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 is where heat gets released to the outside air. The compressor lives inside that cabinet and is one of the first things a contractor looks at when a system stops cooling, because a failed compressor often explains the whole problem.
Inside the house, the air handler or furnace cabinet holds the evaporator coil, which sits in the supply air stream and is a common source of trouble when airflow drops or ice starts forming on the unit. The refrigerant lines running between the two cabinets and the thermostat on the wall are also part of what a contractor traces when diagnosing why a system is underperforming.
The drawing shows a typical central AC layout, and a licensed contractor will determine which components and conditions apply to your specific home.

What the repair work looks like in Park 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.
