A contractor quoting a central AC install in this area starts with load calculations that account for what the system will actually run against, not just square footage. 229 severe weather events were recorded in Deaf Smith County, Texas between 2015 and 2024. At that rate, severe weather is a routine operating condition across the county's life, and a unit that is undersized or has ductwork that was never properly sealed will feel that strain faster than one installed to match the real demand. Sizing and installation quality are local decisions here, not catalog defaults.
Ductwork laid down for equipment that no longer exists is what a contractor walks into on a sizable share of Deaf Smith County jobs. Half the homes in Deaf Smith County, Texas were built in 1971 or earlier (2020-2024 ACS 5-year). Sizing and routing that made sense for an older system often forces a choice on a new installation: adapt what is there or replace it. The electrical picture follows the same logic, with service panels wired for loads that predate modern central AC draws. Neither question gets answered from the street.
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 that do the heaviest work in the system. Inside the house, the air handler or furnace blower sits in a utility closet, attic, or basement and pushes conditioned air through the home.
The evaporator coil mounts directly above the air handler and is where the air gives up its heat before moving into the supply ducts. A copper refrigerant line set runs between the indoor and outdoor units, and a condensate drain line carries away the moisture the coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines exactly which components and configurations apply 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 Deaf Smith County, Texas
