Sizing a central AC system in Hunt County starts with what the climate actually demands of the equipment, and that demand is specific enough to make generic catalog specs a poor guide. 115 severe weather events were recorded in Hunt County, Texas between 2015 and 2024. A contractor quoting an installation here has to account for how hard a system will be pushed on a sustained basis, which shapes both the unit capacity they recommend and how carefully they seal and insulate the ductwork to support it. Get those choices wrong and the system works against itself from day one.
Ductwork laid for a previous generation of equipment does not disappear when a homeowner buys a new system. Half the homes in Hunt County, Texas were built in 1990 or earlier (2020-2024 ACS 5-year). A contractor sizing and installing central AC in this county has to evaluate what those ducts will actually carry under the load a current unit puts on them, which is a different question from whether the equipment itself fits the house. Runs that were sized for something smaller, turns that add static pressure, connections that have shifted over decades: these are what determines whether the install goes straight or whether the duct system has to be corrected before a new unit can do its job.
What a Central AC System Consists Of
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, the mechanical core of the whole system. Inside, the air handler or furnace cabinet mounts in a utility closet, basement, or attic and houses the evaporator coil along with the blower that moves air through the home.
The thermostat goes on an interior wall where the homeowner can reach it and tells the system when to run. A copper refrigerant line set runs between the outdoor and indoor units, and a condensate drain line carries moisture pulled from the air out of the house.
The drawing shows a representative layout, and a licensed contractor determines exactly how each component applies to 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.
Licensing and Legal Requirements in Hunt 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 Events in Hunt County
Extreme weather puts a measurable load on cooling equipment, and Hunt County's climate shapes what a central AC system has to handle year after year. That workload is a local fact, and it bears directly on how a system is sized and installed here.
