Sizing central AC for a home here starts with what the climate actually demands, and a light severe weather record shapes that calculation. 55 severe weather events were recorded in Kent County, Texas between 2015 and 2024. At that rate, severe weather is an occasional event rather than a standing operating condition, which means a system's long-term performance is answered more by how it was sized and installed than by what the sky has thrown at it. A contractor quoting a new install in Kent County sets capacity against the real cooling load of the structure, not against a punishing storm history that the data do not show.
Ductwork laid down for an older system carries assumptions about static pressure, sizing, and airflow that a modern central AC unit does not share. Half the homes in Kent County, Texas were built in 1973 or earlier (2020-2024 ACS 5-year). A contractor putting in a new system has to work out whether what is in the walls and ceilings can move air the way the new equipment expects, or whether it will undercut efficiency and strain the unit from day one. The electrical service raises its own questions: panel capacity and circuit configuration from that era often need evaluation before a new unit can be matched and quoted. The equipment choice comes after those answers.
What a Central AC System Includes
The outdoor unit sits on a concrete pad beside the house and holds the compressor and condenser coil. Inside, the air handler or furnace coil assembly mounts in a utility space, attic, or closet and works with the outdoor unit to move conditioned air through the home.
The thermostat goes on an interior wall where it reads the home's temperature and signals the system to run. A refrigerant line set connects the indoor and outdoor equipment, running through the wall or attic to link the two sides of the system.
The drawing shows a typical layout, and a licensed contractor determines exactly how the equipment is configured for this house.

What happens on installation day
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 Kent 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 Events in Kent County
Weather puts a load on cooling equipment, and that load varies by location. What the sky does in Kent County shapes how hard a central AC system has to work and how it should be sized and installed.
