A contractor quoting a central AC install in Garza County has to account for what the equipment will actually run against, not what a standard load calculation assumes. 106 severe weather events were recorded in Garza County, Texas between 2015 and 2024. At that rate, severe weather is part of the normal season here, not an outlier a homeowner might never see. A system undersized or poorly sealed for this climate will strain against conditions that arrive reliably, and the install decisions made on day one set whether it keeps up or falls short. Proper sizing for this area is a local judgment, and a contractor who has worked here makes it differently than one reading from a manufacturer's chart.
Ductwork laid down for older equipment carries different load assumptions than a new central AC system demands, and in Garza County's housing stock that gap is the first thing a contractor has to price out. Half the homes in Garza County, Texas were built in 1973 or earlier (2020-2024 ACS 5-year). A house that old was not built around the tonnage or airflow a modern unit expects, which means the duct configuration gets measured and tested before the equipment is even selected. If the runs are undersized or the layout does not support proper return air, the contractor addresses that first. The electrical service gets the same scrutiny, since the draw of a current system may exceed what the panel was originally rated for.
What a Central AC System Includes
The indoor air handler sits inside the house, usually in a utility closet, attic, or basement, and holds the evaporator coil that pulls heat out of the air moving through your home. The outdoor condenser unit sits on a pad beside the house and carries the compressor and condenser coil, which release that heat outside.
A refrigerant line set runs between the two units, carrying refrigerant back and forth through copper tubing insulated against the Texas heat. A thermostat mounts on an interior wall and is the control point that tells the system when to run.
The drawing shows the standard layout of these components, and a licensed contractor determines exactly how they configure in your home.

What Installation Day 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 Garza 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.
