A contractor quoting a central AC installation in Brevard County starts from what the climate here actually asks of a system, because undersizing is a failure that shows up gradually and expensively. 209 severe weather events were recorded in Brevard County, Florida between 2015 and 2024. At that rate, severe weather is part of the normal operating environment, and a unit sized for a gentler place will run harder, cool less effectively, and wear faster. That shapes which equipment a contractor selects, how they calculate load, and how they seal and support the install from day one.
Ductwork laid down for a unit from a prior generation carries assumptions about airflow, return placement, and static pressure that a new system may not match. Half the homes in Brevard County, Florida were built in 1988 or earlier (2020-2024 ACS 5-year). A contractor quoting a central AC job in a house from that era has to assess whether the existing duct layout can move the air a modern unit produces, or whether sections need to be rebalanced, rerouted, or replaced. The electrical service gets the same look: panel capacity and circuit runs from that period were not specified for today's equipment draws. What a homeowner pays for installation in Brevard is shaped as much by what the house already has as by which unit goes in.
What a Central AC System Looks Like Before Installation
The outdoor condenser unit sits on a concrete pad outside the house and holds the compressor and the condenser coil. The indoor air handler, mounted in a utility closet, attic, or basement, houses the evaporator coil and the blower that moves air through the home. Together these two units form the core of what a contractor brings to the job.
A refrigerant line set runs between the two units, connecting the indoor and outdoor sides through the wall or foundation. A thermostat mounts on an interior wall and gives the homeowner control over the whole system. The drain line runs from the air handler to a nearby floor drain or outside, carrying away the condensation the coil produces.
The drawing shows a typical layout, and a licensed contractor determines what fits the specifics of your 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 Brevard County
Florida's climate puts real stress on cooling equipment, and Brevard County has its own weather pattern that shapes how hard a system has to work and how long it lasts. A contractor sizing and installing central AC here is accounting for local conditions, not a national average.
