Sizing central AC for a house in Winkler County starts with the building: its footprint, insulation, window placement, and how the structure holds or sheds heat through a West Texas summer. 56 severe weather events were recorded in Winkler County, Texas between 2015 and 2024. At that rate, severe weather touches this area occasionally rather than constantly, which means a contractor cannot point to accumulated storm load as the reason a system is undersized or struggling. The equipment choices that matter here come down to how well the unit is matched to the structure and how cleanly the install is executed, not to a climate record that demands special allowances.
Ductwork laid down for equipment that old was sized to move air under conditions that modern central AC systems are not designed to match. Half the homes in Winkler County, Texas were built in 1968 or earlier (2020-2024 ACS 5-year). A contractor quoting a new system in a house from that part of the stock will open registers, check trunk dimensions, and look at how the supply and return runs were originally laid out before the unit itself is priced. What that inspection turns up decides the job. If the existing runs can carry the new system's airflow, the install proceeds on the equipment. If they cannot, the ductwork becomes the first line of work.
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 mounts in a utility closet, attic, or basement and contains the evaporator coil and blower. Together these two units are what a contractor brings in and sets into place.
The thermostat goes on an interior wall where it reads the temperature of the living space and signals the system when to run. A contractor also installs the refrigerant lines that run between the indoor and outdoor units, along with the condensate drain line that carries moisture out of the air handler.
The drawing shows a typical layout, and a licensed contractor determines exactly how the components fit the specific conditions of your house.

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.
What Winkler County, Texas Requires for HVAC Installation
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 History in Winkler County
Weather conditions place real demands on cooling equipment, and those demands are specific to where the equipment runs. A contractor sizing and installing central AC here works against what this county's climate actually does, not a national average.
