A contractor sizing and installing central AC in Baraga County works from the specifics of the house first: load calculations, duct configuration, and how well the original equipment was matched to the space. 86 severe weather events were recorded in Baraga County, Michigan between 2015 and 2024. At that rate, severe weather is part of the local record but not the defining pressure on a system's life. What determines how long a new install lasts here is how accurately it was sized and how cleanly it was set up, and a contractor who skips that work cannot fix it with a better unit.
Ductwork laid in for a furnace was sized around air volumes and pressures that a central cooling system does not share, and in Baraga County's older housing stock that gap shows up early in an installation job. Half the homes in Baraga County, Michigan were built in 1973 or earlier (2020-2024 ACS 5-year). A contractor putting in central AC has to assess what those ducts will actually carry before anything else is priced or ordered. If the existing runs are too narrow or the returns too few, the electrical panel becomes the secondary question. Both answers come from what is in the house, not from the equipment selected.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a pad outside the house and holds the compressor and condenser coil, the two components that do the heaviest work in the system. Inside, the air handler or furnace cabinet mounts in a utility space, basement, or closet and holds the evaporator coil, which is where the indoor side of the process takes place.
A refrigerant line set runs between the two units, connecting the outdoor and indoor sides through a small penetration in the wall. A thermostat goes on a main living-area wall and gives the homeowner direct control over the whole system.
The drawing shows the typical layout of these components, and a licensed contractor determines exactly how each one is positioned and configured for this house.

What the installation looks like from 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.
