Sizing a central AC system for a Shackelford County home is a question of sustained summer heat, not storm exposure. 59 severe weather events were recorded in Shackelford County, Texas between 2015 and 2024. At that rate, severe weather is an occasional disruption rather than a steady load, which means the decisions that matter most on an install are duct layout, equipment capacity, and the quality of the refrigerant charge. A contractor who gets those right gives the system its best chance. Weather here is not the variable that drives the spec.
Ductwork laid down for an older system was sized for what that system needed, and a central AC unit built to current standards draws differently. Half the homes in Shackelford County, Texas were built in 1970 or earlier (2020-2024 ACS 5-year). For a contractor sizing and placing new equipment in stock this old, the duct runs get measured and pressure-tested before the unit is priced, because the existing layout determines whether the new system delivers what it should or fights the house from day one. The electrical service gets the same look, since a panel installed alongside that original ductwork was built to a different load.
What a Central AC System Includes
The indoor air handler sits inside the home, usually in a utility closet, attic, or basement, and it holds the evaporator coil that pulls heat out of your indoor air. The outdoor condenser unit sits on a pad beside the house and releases that heat outside. A contractor sets both units in place and connects them as a matched pair.
The refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated copper tubing. A thermostat on an interior wall ties the whole system together, reading the temperature and telling the equipment when to run.
The drawing shows the general layout of a central AC system, and a licensed contractor determines exactly what applies to your home and its existing setup.

What the Installation Actually 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.
Licensing Rules for HVAC Work in Shackelford County, Texas
In Texas a person may not engage in air conditioning and refrigeration contracting unless that person holds a license issued under the state air conditioning and refrigeration contractor law.
Severe Weather Events in Shackelford County
Weather extremes put real hours on HVAC equipment, and Shackelford County gets its share of what West Texas can deliver. A system sized and installed for local conditions carries a different load than one built to a national average, which is why the pattern here matters when choosing and placing central AC.
