A central AC compressor in La Plata County sits off through every cooling season it will ever see. Homes in La Plata County, CO have essentially no cooling season — no month of the year is warm enough to call for it. Dormant equipment develops its own failure modes: seals dry, contactors corrode, and capacitors drift out of spec with no runtime to flag the change early. When a homeowner calls for a repair, the contractor is working through a system that likely failed on its first real demand in years, not one worn down by heavy seasonal use. Refrigerant leaks, failed start capacitors, and seized contactors move to the top of the diagnostic list because they are exactly what long-idle compressors produce.
Ductwork in this county's older houses was sized and sealed for equipment that is no longer in them, and a repair call is where that gap surfaces. Half the homes in La Plata County, Colorado were built in 1993 or earlier (2020-2024 ACS 5-year). When a unit fails and a contractor opens it up, the question is whether what they find inside is a parts situation or a system situation, and the ductwork's condition is usually part of the answer. Parts availability depends on what generation of equipment is in the house, and that is not always obvious until the unit is open.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and houses the compressor and condenser coil. These are the pieces a contractor looks at early in a repair call. A failed compressor or a fouled coil will stop the system from shedding heat, and both show up in the same way from inside: the air simply stops getting cold.
The air handler or furnace sits indoors, often in a basement, closet, or utility room, and holds the evaporator coil and blower fan. The evaporator coil is a common source of trouble, particularly when refrigerant is low or airflow is restricted. The expansion valve and refrigerant lines connect the two units, and a problem anywhere along that path will show up in how the whole system performs.
The drawing shows a typical layout, and a licensed contractor will determine which components apply and what condition they are in for your specific home.

What HVAC Repair Looks Like in La Plata 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.
