Sizing a central AC system in Wharton County starts with the house, not with the weather. 33 severe weather events were recorded in Wharton County, Texas between 2015 and 2024. At that rate, severe weather is an event rather than a condition, and a contractor who adjusts a quote primarily around storm resilience is solving the wrong problem. What drives a good install here is accurate load calculation, proper duct design, and refrigerant charge. Those are the variables a Lone Star Cooling contractor pins down before equipment is ever specified.
Ductwork sized and routed for older equipment is the part of a central AC installation that most often drives the scope of the job in Wharton County. Half the homes in Wharton County, Texas were built in 1980 or earlier (2020-2024 ACS 5-year). A system designed for current efficiency standards moves air differently than what those ducts were built to handle, so a contractor opening the walls finds whether the existing runs need to be modified, resealed, or replaced before the new unit can be set. The electrical service gets the same look: what the house carries and what the new equipment draws have to match before anything is connected.
What a Central AC System Is Made Of
The outdoor condenser unit sits outside the house, usually against an exterior wall, and houses the compressor and condenser coil. Inside, the air handler or furnace with an evaporator coil sits in a closet, attic, or utility room and works with the outdoor unit to move conditioned air through the home.
The thermostat mounts on an interior wall and serves as the control point for the whole system, telling it when to run and when to stop. A condensate drain line runs from the indoor unit to carry away moisture, and refrigerant lines connect the indoor and outdoor units through the wall or floor.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the specifics of your house.

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 Wharton 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 Wharton County
Local weather puts real stress on cooling equipment, and how hard a system works over its life is shaped by what the climate asks of it. That makes weather history a practical part of any conversation about what to install and how to size it.
