Sizing a central AC system in Maverick County starts with what the equipment will actually run against, and the weather record here makes that a concrete question. 35 severe weather events were recorded in Maverick County, Texas between 2015 and 2024. At that rate, severe weather is part of the baseline an installer works from, not a rare variable they can set aside. A contractor quoting the job has to right-size the equipment and the installation quality for a climate that pushes systems hard on a regular basis. Get that wrong and the system is undersized before the first summer ends.
Ductwork laid down for an older generation of equipment may be the wrong size, the wrong layout, or both for a modern central AC system. Half the homes in Maverick County, Texas were built in 1997 or earlier (2020-2024 ACS 5-year). A contractor quoting an installation here has to assess what those ducts can actually carry before the new unit is even selected, because undersized or poorly routed duct runs will choke the system's output regardless of what the outdoor unit is rated for. The electrical service in houses of that vintage also gets checked early: modern condensing units draw more on startup than older equipment did, and a panel that was adequate then may not be now.
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. Inside, the air handler mounts in a utility closet, attic, or basement and contains the evaporator coil and the blower that moves conditioned air through the home. These two units are the core of what a contractor installs.
A refrigerant line set connects the indoor and outdoor units, running through the wall or attic space to link the two. The thermostat mounts on an interior wall and gives the homeowner control over when the system runs. Both pieces are part of a complete installation.
The drawing shows a typical layout, and a licensed contractor determines exactly what the installation requires in 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 Maverick 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.
