Takes about a minute. No obligation.
A contractor quoting a central AC install in Reagan County starts from the building itself: the insulation, the ductwork, the orientation of the structure and how it sheds or holds heat through a West Texas summer. 56 severe weather events were recorded in Reagan County, Texas between 2015 and 2024. At that rate, severe weather is an occasional fact of life here, and a system that has struggled or failed was almost certainly not brought down by storm load. Sizing the replacement around the house, rather than around the county's weather history, is where the install succeeds or falls short.
Existing ductwork is what a contractor has to assess before anything else on a central AC job here. Half the homes in Reagan County, Texas were built in 1982 or earlier (2020-2024 ACS 5-year). Ducts laid for older equipment were designed around different airflow assumptions, and a new system has to run on what is already in the walls and ceiling. If the trunk lines and branch runs cannot move the volume the new unit requires, the installation answer changes before any equipment is ever ordered. The electrical service gets the same look, since panel capacity for a modern condensing unit is not a given in houses of this vintage.
What Goes Into a Central AC Installation
The outdoor condenser unit sits on a concrete pad outside the house and holds the compressor and condenser coil, which are the system's working core. Inside, the air handler mounts in a utility closet, attic, or basement and pushes conditioned air through the home. These two units are what a contractor brings in and sets in place.
A copper refrigerant line set runs between the outdoor and indoor units, connecting them so the system functions as one. The thermostat mounts on an interior wall and gives the homeowner control over when the system runs and at what temperature.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your house and its existing setup.

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.
Licensing Rules for Contractors in Reagan County, Texas
