A contractor quoting a central AC installation in Morris County has to size the system for the house, but the weather record is not what drives that calculation. 40 severe weather events were recorded in Morris County, Texas between 2015 and 2024. At that rate, severe weather is an event here, not a standing condition that compounds year after year on every piece of equipment in the county. A system struggling in this area most likely carries the marks of how it was put in, how old it is, and whether it has been serviced. The local climate shapes the cooling load a contractor sizes against, but it does not excuse a failed component.
Ductwork laid down for an earlier generation of equipment carries assumptions about airflow and static pressure that a modern central AC system does not share. Half the homes in Morris County, Texas were built in 1975 or earlier (2020-2024 ACS 5-year). A contractor sizing and installing a new unit has to treat what is already in the walls and ceiling as an open question, not a given. Trunk lines sized for an older system may restrict the airflow a new unit needs to perform correctly, and the electrical service run to the original equipment may not match what a current-generation condenser draws. The ductwork gets evaluated before the equipment gets priced.
What a Central AC System Includes
The outdoor condenser unit sits on a concrete pad outside the house and holds the compressor and condenser coil, which together shed heat to the outside air. Inside, the air handler or furnace-mounted evaporator coil lives in a closet, attic, or utility room and is the indoor half of the system. These two units are what a contractor brings to a job.
A copper refrigerant line set runs between the indoor and outdoor units, and a condensate drain line carries moisture away from the evaporator coil to a floor drain or outside. The thermostat mounts on an interior wall and is the control point the homeowner interacts with daily.
The drawing shows a representative layout, and a licensed contractor determines exactly what applies to this 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 Morris 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 Morris County
Extreme weather puts a direct load on cooling equipment, from the hours it runs to the conditions it runs in. How hard a system has to work is shaped by what the local climate actually does, and that makes installation sizing a county-level decision.
