A contractor quoting a central AC installation in Comanche County starts from what the house asks of the equipment, not from a history of punishing weather. 50 severe weather events were recorded in Comanche County, Texas between 2015 and 2024. At that rate, severe weather is an occasional event here, not a standing operating condition. Age of the existing system, quality of the previous install, and how the ductwork is laid out are what drive sizing and equipment decisions. A new unit matched to this house and this climate runs against predictable summer heat, and that is the load a contractor prices around.
Ductwork laid down for earlier generations of equipment was sized and routed for what was common then, not for what a contractor installs today. Half the homes in Comanche County, Texas were built in 1977 or earlier (2020-2024 ACS 5-year). When a central AC system goes in, what a contractor has to settle first is whether the existing duct network will carry the new unit's airflow without pressure losses that undercut performance. If the runs are undersized or the trunk layout does not match what the new equipment demands, the duct work becomes the job, not the equipment swap. The electrical panel gets the same scrutiny, since the draw of a current-rated system often differs from what the original service was wired to handle.
What Central AC Puts in Your Home
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and houses the compressor and condenser coil. Inside, the air handler or furnace holds the evaporator coil and the blower that pushes conditioned air through the home.
A refrigerant line set runs between the two units, connecting the indoor and outdoor sides. The thermostat mounts on an interior wall and acts as the system's control point, telling the equipment when to run.
The drawing shows a typical layout, and a licensed contractor determines what fits the setup in your specific house.

What HVAC Installation Looks Like in Comanche County
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.
