Sizing central AC in Van Buren County starts with the house, not the weather. 59 severe weather events were recorded in Van Buren County, Michigan between 2015 and 2024. At that rate, severe weather is an event here, not a standing condition, so a contractor setting equipment capacity is working primarily from the structure: square footage, insulation, window exposure, and duct layout. A system that fails early in this county almost certainly failed because of poor original sizing or deferred maintenance. A well-matched install, done right the first time, carries the real weight.
Ductwork laid down for a furnace and a window unit does not automatically carry a central AC system without a contractor checking whether the runs, returns, and sizing still hold. Half the homes in Van Buren County, Michigan were built in 1978 or earlier (2020-2024 ACS 5-year). That spread across the county's housing means a meaningful share of homes have duct systems that have been patched, rerouted, or left original since the house was built. An installer has to trace what is actually there before the new equipment can be properly matched to it. The electrical panel gets the same look, since the draw a modern central AC unit requires lands on service that was spec'd for a different era of appliances.
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. Inside, the air handler or furnace-mounted evaporator coil lives in a utility room, basement, or attic. Those two units are the core of what a contractor brings to the job.
A refrigerant line set runs between the indoor and outdoor units, connecting the two halves of the system through the wall or floor. The thermostat mounts on an interior wall and gives the homeowner control over when and how the system runs.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific 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 Van Buren County
Weather extremes put real demand on central AC systems, shortening equipment life and driving up operating costs when the hardware is undersized or poorly matched to the local climate. What happens in Van Buren County shapes what a system here needs to handle.
