Takes about a minute. No obligation.
A contractor quoting a central AC installation in Gonzales County is working out what the house actually needs, and the local weather record is a modest part of that calculation. 31 severe weather events were recorded in Gonzales County, Texas between 2015 and 2024. At that rate, severe weather is an event here rather than a standing condition, which means a system's cooling load, the quality of its duct layout, and how the equipment was originally sized carry far more weight than storm exposure when a contractor decides what to put in and how to put it in.
Ductwork laid down for equipment from an earlier era may not move air the way a new central AC unit needs it to. Half the homes in Gonzales County, Texas were built in 1983 or earlier (2020-2024 ACS 5-year). A contractor installing a new system here has to assess what is already in the walls and attic before any equipment gets ordered, because undersized or leaking ducts will undercut whatever efficiency the new unit is rated for. The electrical service gets the same look: older panels were not always wired with today's load requirements in mind. What the house already contains is the job.
What a Central AC System Puts in Your Home
The indoor air handler sits inside the house, most often in a utility closet, attic, or basement, and it holds the evaporator coil that pulls heat from the air moving through it. The outdoor condenser unit sits on a concrete pad beside the house and carries the compressor and condenser coil, which are the mechanical heart of the system.
A refrigerant line set runs between those two units through the wall, carrying the refrigerant back and forth. The thermostat mounts on an interior wall and is what the homeowner actually uses to set temperatures and control the system.
The drawing shows a typical layout, and a licensed contractor determines exactly what fits and where in your specific 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 Gonzales 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 Gonzales County
Extreme weather puts a sustained load on cooling equipment, and what the sky does here shapes what a system needs to handle over its working life. That makes local weather history a practical input for any AC installation decision in this area.
