A contractor quoting central AC installation in Wichita County has to size for a climate that tests equipment hard, not occasionally. 303 severe weather events were recorded in Wichita County, Texas between 2015 and 2024. At that rate, severe weather is part of the baseline operating environment, not an outlier a system might avoid for years. That load shapes which equipment a contractor specifies and how the refrigerant lines, disconnect, and outdoor unit are secured. A system installed without accounting for it will be working against the climate from day one.
Ductwork laid down to move air for older equipment carries different dimensions, different static pressure assumptions, and often different materials than what a new central AC system expects to run against. Half the homes in Wichita County, Texas were built in 1972 or earlier (2020-2024 ACS 5-year). A contractor pricing an installation here measures and inspects that duct system before the equipment selection matters, because a new unit matched to the house but not to the existing duct layout will underperform regardless of its rated capacity. The electrical service gets the same look, since panel configurations from that era were not built around the draw of modern central AC equipment. What the house already contains sets the scope.
What a Central AC System Includes
The indoor air handler sits inside the home, usually in a utility closet, attic, or basement, and it pulls warm air from the house across a refrigerant coil that cools it before pushing it back through the vents. The outdoor condenser unit sits on a concrete pad beside the house and carries the heat collected inside back out into the open air.
A copper refrigerant line set runs between those two units, connecting them through an exterior wall, and a thermostat on an interior wall gives the homeowner control over the whole system. A condensate drain line also runs from the air handler to carry away the moisture that collects on the coil during operation.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions in your home.

What the installation looks like from your end
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 Wichita County, Texas
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 Wichita County
Weather in this part of Texas puts real strain on cooling equipment, pushing systems harder and longer than manufacturers' specs assume in milder climates. How much strain depends on what actually rolls through a given county, which is why local event history matters when sizing and installing central AC.
