The compressor in a central AC unit takes its hardest wear at startup, and a short, concentrated cooling season packs all of that cycling into a narrow window. Homes in Valencia County, NM run cooling about three months a year, from June through August. That means the contactor, the capacitor, and the compressor itself accumulate their season's worth of stress in a short run rather than spreading it across the calendar. A contractor diagnosing a failed unit here checks those components before anything else, because they absorb the load every time the system kicks on against summer heat.
Half the homes in Valencia County, New Mexico were built in 1989 or earlier (2020-2024 ACS 5-year). In stock that old, the ductwork a contractor opens has often been modified more than once, and the system running through it now is rarely the one the house was built around. What that means for repair work is concrete: a refrigerant leak or a failed contactor might be the presenting problem, but the contractor working the job also has to account for duct connections that have loosened over time and linesets that may have been extended or disturbed in a previous repair. Parts availability for equipment in a house this age varies sharply by brand and model, and a contractor pulling a unit apart here has to confirm what the system actually takes before a repair scope is firm.
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 often where a contractor starts when a system stops cooling. A refrigerant leak, a failed capacitor, or a seized compressor will all show up here first.
Inside the house, the air handler or furnace cabinet holds the evaporator coil, which pulls heat out of the indoor air as it passes through. The blower fan that moves air across that coil is another common point of failure, and the refrigerant lines running between the two units carry the working fluid that ties the whole system together.

What happens when the contractor comes out
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.
