A contractor quoting central AC installation in Wilbarger County has to account for what the climate asks of a system year after year, because a unit that is right-sized and properly sealed handles sustained weather load differently than one that was spec'd for a milder place and installed loose. 100 severe weather events were recorded in Wilbarger County, Texas between 2015 and 2024. At that rate, severe weather is a routine condition here, not an occasional event, and the install quality determines how long a system runs against it before a component fails.
Ductwork laid down for an earlier generation of equipment carries assumptions about airflow, load distribution, and return-air placement that may not match what a new central AC system needs to move. Half the homes in Wilbarger County, Texas were built in 1965 or earlier (2020-2024 ACS 5-year). That gap between when the house was built and what runs in it now is where installation work gets decided. A contractor sizing and placing a new system has to establish whether the existing duct layout delivers air where the new unit expects to push it, and whether the electrical service will carry the load. The equipment selection comes after that assessment, not before.
What a Central AC System Is Made Of
The indoor air handler sits inside the house, usually in a utility closet, attic, or basement, and it is where air moves across the cooling coil before traveling through the ducts. The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and the condenser coil. These two units are the core of what a licensed contractor installs.
A copper refrigerant line set runs between the indoor and outdoor units, carrying refrigerant back and forth through the system. The thermostat, mounted on an interior wall, is the control point that tells the system when to run. Both the line set and the thermostat are part of a full central AC installation.
The drawing shows a representative layout, and a licensed contractor determines exactly how each component applies to this house.

What happens when the contractor shows up
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 Wilbarger 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 in Wilbarger County
Weather events put a measurable load on HVAC equipment, and that load varies by where you live. A system sized and installed for Wilbarger County conditions handles what the local climate actually delivers.
