A contractor quoting a central AC installation in Hardin County has to solve a local sizing problem before anything else gets decided. 60 severe weather events were recorded in Hardin County, Texas between 2015 and 2024. At that rate, severe weather is something equipment here encounters but does not run against constantly, which means the system's performance over years will be settled mostly by how well it was sized for the structure and how cleanly the install was executed. A unit undersized for a Hardin County summer will struggle every cooling season regardless of how mild the storm record is.
Ductwork laid down for an older generation of equipment carries assumptions about airflow and load that a new central AC system will test. Half the homes in Hardin County, Texas were built in 1994 or earlier (2020-2024 ACS 5-year). A contractor installing a new unit has to assess whether the existing runs can carry it before anything else on the job is priced, because a duct layout that fell short would push conditioned air into the wrong places and leave the system working against itself. Electrical service is the other check: panels from that era were not always wired for modern draw requirements, and a contractor confirms what is there before the new unit goes in.
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, which are the mechanical core of the system. Inside, the air handler or furnace-mounted evaporator coil lives in a utility space, basement, or attic and is the piece that connects to the home's existing air supply.
The refrigerant line set runs between those two units, linking the indoor coil to the outdoor equipment through the wall or floor. A programmable thermostat mounts on an interior wall and gives the homeowner control over the whole system.
The drawing shows the general layout of a central AC system, 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 Hardin 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 in Hardin County
Storm activity puts real strain on cooling equipment, from hard startups after outages to sustained runs during recovery heat. How often that happens here shapes what a central AC system needs to handle and how it should be installed.
