Takes about a minute. No obligation.
A central AC compressor that has never been asked to run carries its own failure risks. Seals dry out, contacts corrode, and refrigerant settles when a system sits off season after season with no load to cycle through. Homes in Archuleta County, CO have essentially no cooling season — no month of the year is warm enough to call for it. A contractor diagnosing a repair here checks for dormancy damage before assuming wear, because the compressor has had almost no runtime to push problems to the surface. Contactor pitting, dried shaft seals, and refrigerant migration are the findings that fit this pattern.
Ductwork that has carried more than one generation of systems, and components that have been swapped in along the way, shape what a repair here actually costs. Half the homes in Archuleta County, Colorado were built in 1996 or earlier (2020-2024 ACS 5-year). That history means the unit a contractor opens may be running parts that fit the original installation only loosely, sourced from a shrinking supply. When a repair scope comes back wider than expected, the ductwork or an adapted component is often where the answer sits.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and it is where the system sheds heat to the outside air. The indoor air handler or furnace coil lives inside, most often in a basement, closet, or utility room, and a contractor working a repair call starts at both ends: the condenser for refrigerant, electrical, and fan problems, and the indoor coil for freeze-ups and airflow failures.
The refrigerant lines run between the two units, and a leak anywhere along them will pull the whole system down. The thermostat on the wall is the control point, and a wiring fault or a failed sensor there can mimic a much larger problem. The contractor checks both before opening anything else.
The drawing shows a typical central AC layout, and a licensed contractor determines what applies to the specific equipment and configuration in your home.

What HVAC Repair Looks Like in Archuleta 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.
Severe Weather Events in Archuleta County
Extreme weather puts real stress on central AC equipment, and how hard a system works over its life is shaped by what the local climate actually does. The chart below reflects that local record, which is part of why repair needs in Archuleta County look the way they do.
