A contractor quoting central AC installation in Roberts County has to size the system against what the local climate actually demands, and here that demand is substantial. 110 severe weather events were recorded in Roberts County, Texas between 2015 and 2024. At that rate, severe weather is part of the normal operating environment for every system in this area, and a unit sized for average conditions will be working against the local reality from the day it goes in. Duct layout, equipment capacity, and the quality of the installation itself are all questions a contractor answers with that load in mind.
Ductwork laid down for older cooling equipment was sized to move a different volume of air at different pressures than a modern central AC unit demands. Half the homes in Roberts County, Texas were built in 1966 or earlier (2020-2024 ACS 5-year). That means a contractor quoting an installation here has to assess what the existing trunk lines and branch runs will actually carry before the new unit is ever ordered, because ductwork that underdelivers will choke a new system regardless of its rated capacity. The electrical service gets the same look: panel capacity and wire gauges from that era often fall short of what current equipment draws. The unit itself is the straightforward part of the quote; what surrounds it is where the job either holds or changes.
What a Central AC System Includes
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, the two components doing the heaviest work. Inside, the air handler or furnace-plus-evaporator-coil assembly mounts in a utility closet, attic, or basement and handles the air side of the system. These are the main pieces a contractor sources, positions, and connects.
The refrigerant line set runs between the two units, linking the indoor and outdoor sides through a pair of insulated copper lines. A thermostat mounts on an interior wall and gives the homeowner control over the whole system. Each of these pieces has to be sized and placed to work with the others.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your home.

What the Installation 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.
