Takes about a minute. No obligation.
A compressor that spends most of the year switched off faces a different kind of stress than one that cycles through a long season. Homes in Montezuma County, CO run cooling in a single month of the year, July. After months of sitting, the contactor corrodes and the capacitor loses charge-holding capacity, and neither problem shows up until the day a homeowner flips the thermostat in July and the unit refuses to start. A contractor running a repair call here checks those components before anything else, because a hard start after a long idle is where the failure almost always sits.
Ductwork in a house this old has likely fed more than one system over its life, and each swap leaves the refrigerant lines, the air handler mounting, and the filter housing carrying the marks of that history. Half the homes in Montezuma County, Colorado were built in 1986 or earlier (2020-2024 ACS 5-year). When a contractor opens the unit, what they find often determines whether the repair resolves in a single visit or waits on a part that current distributors stock only on order, if at all. That is the real variable in a repair call here.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and it is where the system sheds heat. It holds the compressor and the condenser coil, and both are common starting points when a system runs but does not cool. The air handler or furnace coil indoors carries the evaporator coil, and a failed coil or refrigerant problem almost always shows up there.
The refrigerant lines run between the two units and connect the indoor and outdoor sides of the system. A contractor also checks the expansion valve, the capacitors, and the contactor in the outdoor cabinet, since those smaller components fail more often than the coils themselves and are faster to test and replace.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components and conditions apply to your specific house.

What HVAC Repair Looks Like in Montezuma 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 Montezuma County
Extreme weather puts real stress on central AC systems, pushing compressors, capacitors, and refrigerant lines past what mild conditions demand. How often that stress lands on equipment in Montezuma County shapes how much repair work local systems actually need.
