A contractor quoting a new central AC system in Comanche County has to size it for what this area actually runs against, not for a catalog average. 358 severe weather events were recorded in Comanche County, Oklahoma between 2015 and 2024. At that rate, severe weather is part of the baseline operating environment, and a system that is undersized or loosely installed will show the strain sooner than the equipment's rated life would suggest. A contractor who knows this area specs the unit and the installation to carry that load from day one.
Ductwork laid down for earlier equipment carries assumptions about airflow, static pressure, and trunk sizing that a modern central AC system will test immediately. Half the homes in Comanche County, Oklahoma were built in 1977 or earlier (2020-2024 ACS 5-year). A contractor pricing a new installation here has to assess what is already in the walls and attic before the unit itself becomes relevant, because duct geometry that worked for one generation of equipment can starve or overload the next. That assessment changes the scope of the job in ways no equipment selection resolves on its own.
What a Central AC System Includes
The outdoor condenser unit sits on a concrete pad outside the house and holds the compressor and condenser coil, the two components doing the heaviest mechanical work. Inside, the air handler or furnace cabinet stands in a utility space, basement, or closet and holds the evaporator coil and blower that move conditioned air through the home.
The thermostat mounts on an interior wall and gives the homeowner control over the whole system. A refrigerant line set runs between the outdoor and indoor units, and a condensate drain line carries moisture out of the air handler to a floor drain or exterior discharge point.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this 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.

Severe Weather Events in Comanche County
Weather in Comanche County puts real demands on cooling equipment, and those demands shape what a system needs to handle year after year. Sizing and installing central AC here is a local decision, and local conditions are part of it.
