A contractor quoting a central AC installation in Culberson County has to account for what the system will actually run against, not just square footage. 429 severe weather events were recorded in Culberson County, Texas between 2015 and 2024. At that rate, severe weather is a standing condition of operating here, and a unit sized to a generic load table rather than to this climate will be working beyond its design point before the first summer ends. Compressors, coils, and refrigerant lines specified without that load built in wear faster, and the contractor doing the install carries responsibility for a choice the homeowner cannot make without them.
Ductwork sized and routed for an older generation of equipment may not move air the way a new central AC system requires. Half the homes in Culberson County, Texas were built in 1975 or earlier (2020-2024 ACS 5-year). A contractor installing a new unit in this county has to assess what the existing duct layout will actually deliver before the equipment choice matters much. Trunks that ran fine for what they were built around can starve a modern system, and electrical service from that era sometimes falls short of what current units draw. Those two items, the ductwork and the electrical, are what a contractor works through first.
What Goes Into a Central AC Installation
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil lives in a closet, attic, or utility space and is the indoor half of the system. These two units are what a contractor brings to the job.
A refrigerant line set runs between the indoor and outdoor units, connecting them through the wall or floor. The thermostat mounts on an interior wall and gives the homeowner control over the whole system. Both pieces are part of what a contractor sources and positions during the work.
The drawing shows a typical layout, and a licensed contractor determines what fits and where in your specific home.

What the installation looks like
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 in Culberson County
Weather events put real load on cooling equipment, and how hard a system has to work over its lifetime is a local question. What happens in this part of Texas shapes what a central AC installation needs to handle.
