Sizing a central AC system in Broward County starts with what the equipment will actually run against. 200 severe weather events were recorded in Broward County, Florida between 2015 and 2024. At that rate, severe weather is part of the normal operating life of any system installed here, and a contractor who ignores it will undersize the unit or choose components rated for a lighter load. Refrigerant line sets, disconnect boxes, and condenser pads all carry that load in different ways. Getting the install right means accounting for the climate before anything goes on the truck.
Ductwork sized and routed for older equipment sits inside a large share of the homes a contractor quotes here. Half the homes in Broward County, Florida were built in 1980 or earlier (2020-2024 ACS 5-year). When a new central AC system goes in, what that existing ductwork can actually carry decides more about the job than the unit selection does. Electrical service matters too. A panel that was never updated to handle modern draw adds a separate decision before the install can move forward. The unit itself gets specified in an afternoon; the house tells you whether that specification holds.
The Parts of a Central AC System Being Installed
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, which are the heart of the system. Inside, the air handler mounts in a utility closet, attic, or garage and moves conditioned air through the home. These are the two main pieces a contractor places and connects.
The expansion valve and evaporator coil live inside or directly attached to the air handler, and together they are where the cooling actually happens within that cabinet. A thermostat goes on an interior wall and gives the homeowner control over the whole system.
The drawing shows a typical layout, and a licensed contractor determines exactly what fits and where in your particular house.

What happens on installation day
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.
What Broward County and Florida Require for HVAC Installation
Florida requires a person to be certified or registered in order to engage in the business of contracting in the state.
Severe Weather Events in Broward County
Weather puts a measurable load on cooling equipment, and that load varies by location. How hard a system works over its life is a local fact, and the installation choices that follow from it should be too.
