Sizing central AC in Bandera County starts with what the climate actually asks of a system, and that load is real. 62 severe weather events were recorded in Bandera County, Texas between 2015 and 2024. At that rate, severe weather is a standing feature of the operating environment, not an occasional interruption, and a contractor who ignores it will undersize the equipment or specify components that wear out ahead of schedule. The install itself has to account for that load from day one.
Ductwork sized and routed for an older system carries assumptions a new central AC unit will test. Half the homes in Bandera County, Texas were built in 1997 or earlier (2020-2024 ACS 5-year). A contractor installing a new system in a house from that era has to check whether the existing duct layout moves enough air for modern equipment, and whether the electrical service supports what the new unit draws. If either falls short, those items get priced and addressed before the equipment itself goes in.
What Goes Into a Central AC Installation
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and houses the compressor and condenser coil. Inside, the air handler or furnace with its evaporator coil sits in a utility closet, attic, or basement and is the piece that conditions air before it moves through the house.
The refrigerant line set runs between the two units, connecting the indoor and outdoor sides through the wall or floor. A thermostat goes on an interior wall and gives the homeowner control over the whole system. The contractor also installs a disconnect box near the outdoor unit as part of bringing the system online.
The drawing shows a typical layout, and a licensed contractor determines exactly what the installation involves in 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.
What Bandera County, Texas Requires for HVAC Installation
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 Bandera County
Weather in Bandera County puts real demands on cooling equipment, and those demands shape what gets installed and how it gets sized. A system spec that ignores local conditions is a system that works harder than it should.
