A contractor quoting a central AC installation in Anderson County has to work out what the climate actually demands before they can size equipment correctly. 82 severe weather events were recorded in Anderson County, Texas between 2015 and 2024. At that rate, severe weather is an occasional fact of life here, not a steady grind on outdoor units and compressors. That means a system that has been running poorly is more likely carrying the cost of an undersized original install or deferred maintenance than any accumulated storm damage. A contractor arriving to quote a replacement is solving a sizing and quality problem, and the weather record does not change that calculus.
Ductwork laid down for older equipment carries assumptions about airflow that a modern central AC system does not share. Half the homes in Anderson County, Texas were built in 1985 or earlier (2020-2024 ACS 5-year). A contractor sizing and running new equipment here has to assess what those ducts will actually do under the new load before anything else on the job is priced or scheduled. The electrical service is a second question on the same inspection, since panels in houses of that vintage were not built to the draw a current system places on them. What the house already contains is where the installation budget gets settled.
What a Central AC System Includes
The indoor air handler sits inside the house, most often in a utility closet, attic, or basement, and it pulls warm air from the living space across a coil that cools it before sending it back through the supply vents. The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and the coil that releases heat to the outside air.
A copper refrigerant line set runs between the two units, carrying refrigerant back and forth to keep the cycle going. A programmable thermostat mounts on an interior wall and gives the homeowner control over when and how the system runs.
The drawing shows the general layout of a central AC system, and a licensed contractor determines exactly how each piece fits the conditions of your particular house.

What the installation looks like from your side
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 Anderson County and Texas Require 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 Anderson County
Outdoor conditions drive how hard HVAC equipment works and how long it lasts. What the weather does in this part of Texas is the starting point for sizing and installing central AC that holds up over time.
