Sizing a central AC system for a home in Kimble County starts with what the local climate actually demands, not with a default load calculation pulled from a manual. 60 severe weather events were recorded in Kimble County, Texas between 2015 and 2024. At that rate, severe weather is an event here, not a constant. A contractor quoting an install in this area is not designing around a system that has been battered season after season. Age of existing equipment, installation quality, and duct condition are what shape the job. Those are the variables a contractor establishes before the equipment gets selected.
Ductwork laid down for an older generation of equipment was not designed around what a modern central AC unit moves. Half the homes in Kimble County, Texas were built in 1981 or earlier (2020-2024 ACS 5-year). A contractor installing a new system in housing like this will open registers, measure runs, and check how the existing layout handles current airflow demands before the new unit is ever priced. If the ducting cannot carry what the new system delivers, the equipment underperforms regardless of its rating. The electrical service gets the same scrutiny, since older panels often need upgrading to handle a modern condenser's draw.
What Goes Into a Central AC Installation
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil. Inside, the air handler mounts in a utility closet, attic, or basement and contains the evaporator coil and blower that move conditioned air through the home. These are the two main pieces a contractor sets in place.
A copper refrigerant line set runs between the outdoor and indoor units, connecting them through a small penetration in the wall. The thermostat mounts on an interior wall and gives the homeowner control over the whole system. Both pieces are part of every new installation.
The drawing shows a typical layout, and a licensed contractor determines exactly how each component fits the specific construction of 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 Kimble 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 History in Kimble County
Weather puts a load on cooling equipment that average climate figures never capture. How hard a system works over its life depends on what actually hits the area, which is why local storm history belongs in any honest conversation about AC installation.
