The compressor in a Grant County home runs hard through every week of the cooling season, cycling on and off through the hottest part of the year with little idle time to spare. Homes in Grant County, NM run cooling about three months a year, from June through August. That concentrated workload falls almost entirely on the same components each year: the compressor itself, the contactor that switches it on and off, and the condenser fan that pulls heat out while it runs. When one of those fails, a contractor checks the contactor for pitting and the fan motor for bearing wear before assuming a refrigerant leak, because those parts carry the seasonal load directly.
Parts availability is where many repairs in this county stall. Half the homes in Grant County, New Mexico were built in 1978 or earlier (2020-2024 ACS 5-year). Systems installed into housing that old have since been replaced, upgraded in pieces, or patched with whatever the supply chain offered at the time, and what a contractor opens is rarely a clean original configuration. The search for a compatible part often goes further than the labor does, and whether that part is still manufactured decides more about the repair than the condition of the unit going in.
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 it is where heat from inside the house gets released. The indoor air handler or furnace-mounted evaporator coil sits inside, most often in a closet, basement, or utility room, and it is the piece that pulls heat out of the air moving through your home. When the system blows warm air or stops cooling altogether, a contractor starts at these two components.
The refrigerant lines run between the indoor and outdoor units, and a leak or blockage there can cause either piece to behave as though it has failed on its own. The thermostat, mounted on an interior wall, tells the system when to run, and a fault there can look exactly like a compressor or coil problem until a contractor rules it out.
The drawing shows the typical layout of these components, and a licensed contractor determines which parts apply and what condition they are in for your specific house.

What HVAC Repair Looks Like in Grant 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.
