A contractor quoting a central AC installation in Hockley County has to account for what this climate asks of equipment before they can settle on a system size or specify components. 162 severe weather events were recorded in Hockley County, Texas between 2015 and 2024. At that rate, severe weather is a standing operating condition rather than an occasional disruption, and a system sized for a milder load will run harder and recover slower every time conditions push it. That shapes which equipment a contractor specifies, how they size the refrigerant circuit, and what they put in writing about expected performance.
Ductwork laid down for equipment that has not been manufactured in generations was not built to move the volume or velocity a modern central AC unit needs. Half the homes in Hockley County, Texas were built in 1978 or earlier (2020-2024 ACS 5-year). A contractor installing a new system here will open registers and crawl spaces before the new unit ever enters the conversation, because whether the existing duct network can carry what a current system delivers is the question the job turns on. If the runs are undersized or the layout does not match modern load distribution, the ductwork becomes the scope, and the electrical service gets the same review.
What a Central AC System Includes
The indoor air handler sits inside the house, usually in a utility closet, attic, or basement, and pulls warm air across a coil so cooled air can move through the home. The outdoor condenser unit sits on a concrete pad or mounting brackets outside the house and sheds the heat that was pulled from inside.
The refrigerant line set runs between those two units, carrying the refrigerant that makes the exchange possible. A thermostat on an interior wall ties the whole system together, reading the temperature and telling the equipment when to run.
The drawing shows a typical layout, and a licensed contractor determines what fits the specific configuration of your house.

What Happens During Your HVAC Installation
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 and Legal Requirements in Hockley County, Texas
