A contractor quoting central AC installation in Hartley County has to account for what the equipment will run against from the first season it operates. 216 severe weather events were recorded in Hartley County, Texas between 2015 and 2024. At that rate, severe weather is part of the normal operating environment, which means sizing decisions and equipment selection carry real consequences here. A unit sized for average demand in a milder area will be undersized for what this county actually delivers. The contractor's job is to match the system to the conditions, not to catalog specifications.
Ductwork laid in for older equipment carries assumptions about airflow and return paths that a new central AC system will stress differently. Half the homes in Hartley County, Texas were built in 1979 or earlier (2020-2024 ACS 5-year). A contractor sizing and placing a new system in stock like this has to walk the existing duct runs before quoting the equipment, because what the ducts can carry determines whether they stay or get replaced, and that decision shapes the whole job. The electrical is the second check, since panel capacity for a new condensing unit is not a given in a house wired for what was standard when it was built.
What a Central AC System Includes
The indoor air handler sits inside the house, usually in a utility closet, attic, or basement, and it holds the evaporator coil that pulls heat out of the air moving through your home. The outdoor condenser unit sits on a pad beside the house and carries the compressor, which does the heavy work of the refrigeration cycle.
A copper refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated tubing. A thermostat mounts on an interior wall and acts as the control point, telling the system when to run and when to stop.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house and its existing setup.

What happens during an HVAC installation in Hartley County
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.
