Sizing a central AC system for a Sheboygan County home requires a contractor to account for local weather as a routine operating condition, not an edge case. 89 severe weather events were recorded in Sheboygan County, Wisconsin between 2015 and 2024. At that rate, severe weather is a real part of what a system runs against here, and a contractor pricing an install has to size accordingly rather than pulling a number from a catalog. A unit undersized for this area will cycle harder and wear faster than its rated life suggests.
Ductwork laid in for an older heating system carries assumptions about airflow that a central AC installation will test. Half the homes in Sheboygan County, Wisconsin were built in 1970 or earlier (2020-2024 ACS 5-year). A contractor sizing and fitting a new unit has to work out whether that existing duct network can move the volume a modern system pushes, and whether the electrical service the house was built with meets what the new equipment draws. Those two questions are where the job's scope gets settled, and neither one can be answered from the street.
What Goes Into a Central AC Installation
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and holds the compressor and condenser coil. Inside, the air handler or furnace-mounted evaporator coil sits in a utility space, basement, or closet and is where the refrigerant does its work on the air passing through.
A refrigerant line set runs between the two units, connecting the indoor and outdoor sides through the wall or floor. A thermostat goes on an interior wall where it can read the house temperature and tell the system when to run.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.

What the contractor does, and what to expect on your end
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 Sheboygan County, Wisconsin
A Wisconsin business that employs a certified HVAC qualifier is a certified HVAC business, and no city or county may require it to hold a local certification or licence on top of that.

Severe Weather Events in Sheboygan County
Weather puts a measurable load on HVAC equipment, and that load is specific to where you live. A system sized and installed for Sheboygan County's conditions handles the work asked of it; one that isn't matched to local reality works harder than it should.
