A contractor quoting central AC installation in Ochiltree County cannot treat equipment sizing as a catalog exercise. 192 severe weather events were recorded in Ochiltree County, Texas between 2015 and 2024. At that rate, severe weather is part of what every system here runs against season after season, and a unit specified without accounting for that load will be undersized for the actual demand. A contractor who knows this area selects equipment and plans the install around conditions that are routine here, not theoretical.
Ductwork laid down for equipment from an earlier era was sized and routed around what that equipment asked of it. Half the homes in Ochiltree County, Texas were built in 1976 or earlier (2020-2024 ACS 5-year). When a contractor quotes a central AC installation here, what that existing duct system can actually carry determines the scope of the job before the new unit is ever ordered. Flex runs that were added over the decades, original trunk lines that were never meant for today's load calculations, connections that have shifted or degraded: these are what the installer has to open, measure, and assess. The electrical service is the other variable, since panel capacity and wiring gauge for a house of this vintage were set by standards that predate modern equipment draws. The equipment itself gets selected after those two questions are answered.
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, the two components that shed heat to the open air. Inside, the air handler or furnace-mounted evaporator coil lives in a closet, attic, or utility space and is the indoor half of the system.
A refrigerant line set runs between those two units, connecting the indoor coil to the outdoor unit through the wall or roofline. The thermostat mounts on an interior wall and is what the homeowner uses to tell the system what to do.
The drawing shows a typical layout, and a licensed contractor determines exactly what the installation involves in your home.

What happens when the contractor comes out
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 Ochiltree County, Texas
