Sizing a central AC system in Franklin County starts with the house, the ductwork, and the quality of what was put in before. 60 severe weather events were recorded in Franklin County, Texas between 2015 and 2024. At that rate, severe weather sits in the background rather than defining what the equipment has been asked to carry. A contractor quoting an installation here will focus on load calculations, equipment fit, and how well the existing infrastructure can support a new system. Blaming weather for a underperforming install would not hold up.
Existing ductwork in a Franklin County home carries the installation forward or stops it. Half the homes in Franklin County, Texas were built in 1988 or earlier (2020-2024 ACS 5-year). Ducting and electrical service sized for the equipment of that era often fall short of what a current central AC unit requires, and a contractor has to open, measure, and assess both before the equipment choice is settled. A new unit quoted without that inspection is a unit quoted against guesswork.
What a Central AC System Includes
The indoor air handler sits inside the house, usually in a utility closet, attic, or basement, and it holds the evaporator coil that pulls heat out of your indoor air. The outdoor condenser unit sits on a pad beside the house and sheds that heat outside. A contractor sets both units in place and connects them as a matched pair.
The refrigerant line set runs between the two units, carrying refrigerant back and forth through insulated copper tubing. The thermostat mounts on an interior wall and is the control point for the whole system, telling it when to run and when to stop.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific home.

What the installation 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 Franklin 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 Franklin County
Weather shapes how hard cooling equipment works and how long it lasts. What hits Franklin County directly affects what a central AC system needs to handle here, which is why local conditions factor into any honest installation decision.
