Sizing a central AC system in Potter County starts with what the equipment will run against for years, not just what cools a square-footage estimate on paper. 406 severe weather events were recorded in Potter County, Texas between 2015 and 2024. At that rate of exposure, severe weather is a condition of normal operation here, and a contractor quoting an installation has to account for it when selecting equipment grades, specifying refrigerant line protection, and choosing where and how the outdoor unit is anchored. A unit installed to minimum spec in a county with this kind of sustained load will work the same components harder and sooner than one specified with that load already priced in.
Ductwork laid down for the cooling loads of an earlier era was not built to carry what a modern central AC system moves through it. Half the homes in Potter County, Texas were built in 1963 or earlier (2020-2024 ACS 5-year). A contractor quoting an installation here has to assess whether the existing duct network can handle the static pressure and airflow a new unit requires, and in stock this old that answer is not assumed from the permit or the floor plan. If the ducts cannot carry it, the duct work is part of the job. The electrical service gets the same look, since the draw on a new unit may exceed what the original panel was wired to deliver.
What Central AC Puts in Your Home
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, the hardware that does the heaviest work in the system. Inside, the air handler or furnace cabinet stands in a utility closet, basement, or attic and contains the evaporator coil along with the blower that moves air through the house.
The thermostat mounts on an interior wall and is the control point a homeowner touches every day. A refrigerant line set runs between the outdoor and indoor units, and a condensate drain line carries moisture pulled from the air out of the house.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your home's specific configuration.

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.
Licensing and Legal Requirements in Potter 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 Potter County
Extreme weather puts mechanical stress on cooling equipment, and how hard a system works over its life is shaped by local conditions. Central AC sized and installed for Potter County's climate holds up differently than equipment specified somewhere else.
