The compressor in a central AC unit starts and stops every time the thermostat calls for cooling, and in Chaves County that cycling adds up fast. Homes in Chaves County, NM run cooling about four months a year, from June through September. By the time a system shows a fault, the compressor contacts, the condenser fan motor, and the capacitor have each absorbed seasons of that load. A contractor diagnosing a repair here checks those components first, because repeated thermal cycling degrades them before most other parts give out.
Ductwork laid for an earlier era of equipment gets adapted, re-routed, and patched as systems come and go, and what a contractor finds when the unit comes apart often reflects that layered history. Half the homes in Chaves County, New Mexico were built in 1972 or earlier (2020-2024 ACS 5-year). That age of construction means the system a contractor opens today is frequently not the first, second, or even third to occupy the same air handler closet, and earlier retrofits leave their mark on flue connections, refrigerant line routing, and electrical runs that were never quite brought up to the current unit's spec. Parts availability for what is actually inside the cabinet, once opened, is what determines whether a repair closes in one visit or stretches into a sourcing problem.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house and holds the compressor and condenser coil, which are where most repairs start. The compressor is the heart of the system, and a failed one is usually what takes a central AC down entirely. The condenser coil, wrapped around it, sheds heat to the outside air and gets checked for damage and blockage.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower fan. The evaporator coil sits above the furnace or inside the air handler and is where refrigerant does its work on the indoor air. The blower pushes that air through the house, and a contractor will check both when airflow or cooling is off. The refrigerant lines and the thermostat round out what gets inspected.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which parts apply to your specific house and situation.

What HVAC Repair Looks Like in Chaves 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.
