Takes about a minute. No obligation.
A contractor quoting a central AC installation in Collingsworth County has to size the unit for what the air outside actually does, not for what a catalog default assumes. 118 severe weather events were recorded in Collingsworth County, Texas between 2015 and 2024. At that rate, severe weather is a standing condition in this area, and a system sized for milder operating conditions will run harder and longer than it was built to. A contractor who accounts for that load at the design stage avoids a unit that hits its limits before the warranty period closes.
Ductwork laid down for a furnace and never touched since does not automatically carry a modern central AC system. Half the homes in Collingsworth County, Texas were built in 1961 or earlier (2020-2024 ACS 5-year). A contractor sizing a new unit here has to assess what the existing distribution system will actually do under cooling demand, which means pulling registers, measuring runs, and checking whether the supply layout matches the load the new equipment puts out. If the ductwork falls short, that work gets priced and scheduled before the equipment ever ships.
What a Central AC System Includes
The indoor air handler sits inside the house, most often in a utility closet, attic, or basement, and it pulls warm air across a coil to cool it before sending it back through the vents. The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and the condenser coil.
A metering device, usually a small expansion valve, sits between those two coils and controls how refrigerant moves between them. Copper refrigerant lines run between the indoor and outdoor units, and the thermostat on an interior wall ties the whole system together by reading the temperature and telling each piece when to run.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which configuration and components apply to your specific 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 Rules for Collingsworth 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 Collingsworth County
Weather in this part of Texas puts real demand on cooling equipment, and that demand shapes what a system needs to handle over its life. How hard a unit works, and how often, is a local question.
