A contractor quoting a central AC install in Benzie County has to think about what drove the previous system into the ground before they can size the replacement correctly. 35 severe weather events were recorded in Benzie County, Michigan between 2015 and 2024. At that rate, severe weather is a real but infrequent presence, not a grinding constant. A compressor that gave out here carried a lighter weather load than many systems elsewhere face, which means age and the quality of the original install are the honest explanations for most failures a contractor finds. Sizing for this climate means accounting for summer cooling demand, not for weather punishment that the record shows is sporadic.
Ductwork sized and routed for a furnace does not automatically carry a central AC system well. A contractor installing central AC in Benzie County has to assess what is already in the walls and crawlspaces before the new equipment matters much at all. Half the homes in Benzie County, Michigan were built in 1985 or earlier (2020-2024 ACS 5-year). That means a large share of the houses here were built before central cooling was a design assumption, and the duct layouts reflect it. Electrical service is the same story: what was wired for the original loads gets measured against what a new unit will actually draw.
What a Central AC System Includes
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, which together release heat to the outside air. Inside, the air handler or furnace cabinet stands in a utility space, basement, or closet and houses the evaporator coil that pulls heat from your home's air.
The refrigerant line set runs between those two units, carrying refrigerant through insulated copper tubing that connects the indoor and outdoor sides into a single loop. A thermostat on an interior wall ties it all together, reading the temperature and signaling both units when to run.
The drawing shows the typical layout of these components, and a licensed contractor determines exactly how they apply to your 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.

Severe Weather Events in Benzie County
Weather puts a measurable load on cooling equipment, and that load varies by where you live. A contractor sizing and installing central AC here is working against local conditions, not a national average.
