Takes about a minute. No obligation.
A contractor quoting a central AC installation in Cochran County has to work out what the local climate actually asks of a system before settling on equipment size and spec. 93 severe weather events were recorded in Cochran County, Texas between 2015 and 2024. That puts this area in the middle of the national spread, so severe weather is a real but occasional factor rather than a constant one grinding on every component. What that means for an install is concrete: the sizing decision rests on local cooling demand, but the contractor has no reason to spec for punishment the area does not routinely deliver. A system that fails here was almost certainly under-sized, poorly installed, or simply old.
Ductwork laid down for an older system was sized and routed for that system's airflow, not a modern one's. Half the homes in Cochran County, Texas were built in 1971 or earlier (2020-2024 ACS 5-year). A contractor pricing a new central AC unit here has to assess what is already in the walls and attic before the equipment selection means anything, because ductwork that cannot move the air a new unit pushes will undercut the installation regardless of what unit goes in. The electrical service carries the same question: whether the panel can handle what the new equipment draws. Those two things, not the unit itself, are what set the scope and the final number.
What a Central AC System Is Made Of
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and holds the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil sits in a utility space, basement, or closet and is the indoor half of the system. Together these two units form the core of what a contractor installs.
The refrigerant line set runs between the outdoor and indoor units, carrying refrigerant through copper tubing that gets routed along the exterior or through a wall chase. A thermostat mounts on an interior wall and gives the homeowner control over the whole system, signaling when the equipment should run.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the specifics of your home.

What happens when the contractor shows up
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 Rules for Cochran 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.
Severe Weather Events in Cochran County
Weather puts a load on cooling equipment, and that load is local. What the climate does in this part of Texas shapes what a central AC system has to handle and how contractors size and install it here.
