A contractor quoting a central AC install in Ector County has to treat the local weather load as a given, not a variable. 217 severe weather events were recorded in Ector County, Texas between 2015 and 2024. At that rate, severe weather is a routine condition of operation here, and a system that is undersized or installed with shortcuts in the ductwork will feel it sooner. What that means for an install is that the spec and the quality of the seal matter more than which unit gets bolted to the pad. A contractor who sizes correctly and closes the envelope tight gives a system its best chance of holding up against what this area actually delivers.
Ductwork laid down for earlier equipment carries assumptions about airflow, static pressure, and load that a modern central AC unit does not share. Half the homes in Ector County, Texas were built in 1984 or earlier (2020-2024 ACS 5-year). A contractor installing a new system has to evaluate what those ducts will actually do under the new unit's demands, not simply whether they look intact. Flex joints that have held for decades can still be undersized for a current-generation system's output. The electrical service gets the same scrutiny, since panel capacity and circuit runs from that period reflect what was standard then. Both have to be confirmed before the equipment selection means anything.
What a Central AC System Includes
The indoor air handler sits inside the home, usually in a utility closet, attic, or basement, and it pulls warm air across a cold coil to drop the temperature before pushing that air back through the house. The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and the coil that releases heat outside.
A metering device, typically an expansion valve, connects the two main units by regulating refrigerant flow between them. The thermostat mounts on an interior wall and serves as the control point, telling the system when to run and when to stop.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to the specific conditions of your home.

What the installation looks like from start to finish
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 Ector 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 Ector County
Extreme weather puts direct stress on HVAC equipment, shortening run cycles, raising demand loads, and accelerating wear on components sized for average conditions. What the climate does in Ector County shapes what a central AC installation needs to handle, which is why local weather history belongs on a page about this work.
