Sizing central AC in Panola County requires a contractor to treat severe weather as a standing variable, not an occasional one. 123 severe weather events were recorded in Panola County, Texas between 2015 and 2024. At that rate, a unit is being asked to perform under real stress as a routine matter, and a system sized for mild conditions will be undersized for what this area actually delivers. A contractor quoting a new install here factors that load into equipment selection and duct design before settling on any unit.
Ductwork laid down for an earlier generation of equipment carries assumptions about airflow, return paths, and load distribution that a modern central AC system does not share. Half the homes in Panola County, Texas were built in 1984 or earlier (2020-2024 ACS 5-year). A contractor sizing a new unit here has to run the duct system against what the new equipment actually needs, not against what the original installer planned for. If the runs are undersized or the returns too few, the equipment will be correct and the installation will still underperform. The electrical is a separate check, because the service a house of that era was wired for and what a current-rated central system draws are not the same figure. The ductwork and the panel together decide how the job scopes out.
What a Central AC System Includes
The outdoor condenser unit sits outside the house, usually on a concrete pad at the side or rear, and houses the compressor and condenser coil. The indoor air handler or furnace sits inside, most often in a closet, attic, or mechanical room, and moves air across the evaporator coil before sending it through the house.
The refrigerant line set runs between the two units, carrying refrigerant through a pair of insulated copper lines that pass through an exterior wall. The thermostat mounts on an interior wall and is the control point that tells the rest of the system when to run.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits into your home.

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 Panola 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 Panola County
Weather puts a measurable load on cooling equipment, and that load is set by local conditions, not regional averages. A central AC system sized and installed for what Panola County actually sees will run more reliably and last longer than one spec'd for somewhere else.
