A contractor quoting a central AC install in Swisher County has to account for what the equipment will run against year after year, not just on its worst day. 137 severe weather events were recorded in Swisher County, Texas between 2015 and 2024. At that rate, severe weather is part of the normal operating load, not an outlier, and a system sized or installed to a looser standard will feel that pressure in the equipment's performance and service life. Getting the load calculation and the install right from the start is what keeps a unit in Swisher County doing its job through what this climate regularly delivers.
Ductwork laid down for early mechanical cooling was sized and routed around the assumptions of its era, and a new central AC system runs on different assumptions. Half the homes in Swisher County, Texas were built in 1961 or earlier (2020-2024 ACS 5-year). A contractor installing a new unit in stock like this has to determine whether the existing duct runs can handle the load and airflow a modern system delivers, or whether sections need to be replaced, rerouted, or added. The electrical service gets the same look, since what a new condenser draws may exceed what the panel was wired to supply. Those two variables, not the equipment selection, are what set the scope and the price of the job.
What a Central AC System Is Made Of
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and holds the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil sits in a utility space, attic, or closet and is the indoor half of the system. These two units are the core of what a central AC installation puts in place.
A copper refrigerant line set runs between the outdoor and indoor units, connecting the two halves of the system. The thermostat mounts on an interior wall and is the control point for the whole system, telling it when to run and when to stop.
The drawing shows a typical layout, and a licensed contractor determines what applies to this specific house.

What the installation 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.
What Swisher County, Texas Requires for HVAC Installation
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 Swisher County
