Sizing a central AC system for this house requires a contractor to establish what the compressor will actually be asked to do before they write a quote. Homes in Curry County, NM run cooling about three months a year, from June through August. The compressor, the condenser fan, and the contactor each sit idle through fall, winter, and spring, then start working hard in June. Equipment that was undersized or installed without a proper load calculation does not reveal itself gradually. It fails on the first genuinely hot day, after a long idle period, when every other homeowner in the county is calling too.
Ductwork that was sized for a different system is the first thing a contractor opens up on a central AC installation here. Half the homes in Curry County, New Mexico were built in 1976 or earlier (2020-2024 ACS 5-year). That history means the ducts already in the house were designed around equipment that has since been replaced at least once, and whether they can carry what a new unit delivers is a question of measurement, not assumption. A contractor who skips that check prices the wrong job. The electrical panel gets the same look, because the load a modern central system draws has to match what the house actually has.
What a Central AC System Is Made Of
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and holds the compressor and condenser coil. Inside the house, the air handler or furnace coil sits in a utility closet, basement, or attic and works with the outdoor unit to condition the air that moves through your home.
A refrigerant line set runs between the two units, carrying refrigerant through copper tubing that passes through an exterior wall. A thermostat on an interior wall is what the homeowner uses to set temperatures and signal the system to run.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the specifics of your house.

What happens on installation day in Curry 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 Curry County
Weather puts real load on cooling equipment, and how hard a system has to work is shaped by local conditions, not regional averages. That load is part of what a contractor accounts for when sizing and installing central AC here.
