Central AC installation in Kerr County starts with what the climate actually asks of a system, and that picture is neither extreme nor ignorable. 105 severe weather events were recorded in Kerr County, Texas between 2015 and 2024. At roughly the middle of the national distribution, this is not a place where severe weather dominates every decision a contractor makes on sizing or equipment selection. What it does mean is that the installation itself carries most of the weight: a correctly sized, well-sealed system handles this climate without strain, and a poorly specified one struggles regardless of which season it is.
Ductwork sized and routed for older equipment may not move air the way a current system needs it to. Half the homes in Kerr County, Texas were built in 1987 or earlier (2020-2024 ACS 5-year). A contractor quoting a central AC install here has to look at what the existing duct layout actually does before pricing the unit, because a mismatch between the two shows up as uneven rooms and strained equipment, not as an obvious installation problem. The electrical service gets the same read: what the house was wired to carry and what a modern unit draws are questions a contractor answers at the panel, not at the equipment.
What a Central AC System Includes
The indoor air handler sits inside the house, usually in a utility closet, attic, or basement, and it pulls warm air across a refrigerant-filled coil to cool it before sending it back through the vents. The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, where heat pulled from inside gets released to the outside air.
The two units connect through a pair of refrigerant lines that run between the outdoor pad and the indoor cabinet, carrying refrigerant back and forth. A thermostat on an interior wall ties everything together, reading the temperature in the home and telling the system when to run.
The drawing shows a typical layout, and a licensed contractor determines what fits the configuration of your specific house.

What the installation actually looks like
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 Kerr 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 Kerr County
Weather puts real demand on cooling equipment, and that demand is local. Knowing what the climate here has thrown at homes shapes how a contractor sizes and installs a system built to hold up.
