Size the equipment wrong and the compressor pays for it. Homes in Drew County, AR run cooling about five months a year, from May through September. Contractors quoting a central AC install here have to run a proper load calculation first, because a unit that is too small runs long cycles trying to catch up, and one that is too large short-cycles, which hammers the contactor and stresses the capacitor every time it kicks on. Both failure modes accelerate on a compressor that works through a full cooling season rather than a partial one. A contractor who skips the calculation and pulls a unit off the shelf is setting the homeowner up for a service call on the parts that cycle hardest.
Existing ductwork is what a central AC installation in Drew County actually turns on. Half the homes in Drew County, Arkansas were built in 1985 or earlier (2020-2024 ACS 5-year). Houses built by that point were ducted for the equipment of their era, and the gap between what those ducts were sized to carry and what a modern central system moves is where contractors find the real scope of the job. A new unit that is matched to the house but forced through undersized or deteriorated ductwork runs hard and delivers poorly. The electrical service gets checked too, but in stock this age it is usually the duct system that determines whether the install goes in clean or opens into a larger project.
What a Central AC System Is Made Of
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, which together shed heat to the outside air. Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower that moves air through the home. These are the two main pieces a homeowner is buying.
The refrigerant line set runs between the two cabinets, carrying refrigerant back and forth through a pair of insulated copper lines. A condensate drain line runs from the indoor cabinet to a floor drain or outside, pulling away the moisture the coil collects. A thermostat on an interior wall ties the whole system together and tells it when to run.
The drawing shows a typical layout, and a licensed contractor determines what applies to this particular 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.

Severe Weather Events in Drew County
Weather stress accumulates in the equipment that runs through it. A central AC system sized and installed for local conditions holds up better than one that was not, and what the sky does in Drew County is part of that calculation.
