A contractor quoting a new central AC installation in Texas County starts from the climate before they start from the house. 363 severe weather events were recorded in Texas County, Oklahoma between 2015 and 2024. At that rate, severe weather is part of the normal operating life of any system installed here, not an occasional interruption to it. That means sizing decisions and equipment selection are local judgments, shaped by what the air and the conditions in this area persistently ask of a compressor and its components. A contractor who skips that step leaves the homeowner with a system quoted for somewhere else.
Existing ductwork in Texas County homes is the first thing a contractor prices, not the unit itself. Half the homes in Texas County, Oklahoma were built in 1976 or earlier (2020-2024 ACS 5-year). Duct runs laid down for older equipment were designed around different static pressures and airflow volumes than a modern central AC system demands, and a house that has changed hands and had systems swapped over the years may have ductwork that has been patched, re-routed, or left undersized for what sits on it now. The electrical service gets the same look, since a new unit's draw has to land somewhere on the panel. What a contractor quotes on the equipment is the straightforward part; what they find in the attic and at the breaker box is what sets the actual scope.
What a Central AC System Includes
The outdoor condenser unit sits outside the house, usually along a side or rear wall, and holds the compressor and condenser coil. Inside, the air handler or furnace cabinet stands in a utility space, basement, or closet and moves air through the home. Together, these two units are what a new central AC installation puts in place.
The refrigerant line set runs between the indoor and outdoor units, carrying refrigerant through insulated copper tubing that passes through the wall. A thermostat on an interior wall ties the whole system together, giving the homeowner control over when the equipment runs and what temperature it holds.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the specifics of your home.

What HVAC Installation Looks Like in Texas County
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 Texas County
Oklahoma weather puts real demands on cooling equipment, and those demands vary by location. How hard a system has to work, and how reliably it needs to hold up, is a local question that local weather history helps answer.
