A central AC install in Miami-Dade is more than swapping boxes. Permits, inspections, electrical capacity, and line set routing matter, especially in retrofits and condo buildings with limited chase space.
Before install day
Load calculation (Manual J or equivalent), equipment selection matched to duct design, permit pull, and coordination with any HOA rules. Line sets, disconnects, and condensate routing should be planned, not improvised on the roof.
After equipment is set
Vacuum and charge per manufacturer, airflow verification at registers, thermostat programming, and customer walkthrough. Failed inspections delay occupancy on renovations—our team handles inspection corrections when prior work did not meet code.
Right-size the system using AC sizing guidance for Miami and compare long-term efficiency in heat pump versus traditional AC if you are upgrading both heating and cooling hardware.
Duct modifications during install
Many retrofits need return upgrades or plenum fixes. Install day is the right time to address undersized returns that caused comfort issues for years. Skipping that leaves the new equipment fighting old duct mistakes.
Line set and pad details
Proper pads, vibration isolation, and line insulation matter in sun and rain. Inspect before concrete cures and before inspectors arrive. Failed inspections delay occupancy on renovations—see inspection corrections if you inherit someone else’s mistakes.
Commissioning and customer handoff
You should receive model numbers, warranty registration steps, and thermostat instructions. Run the system through a full cycle before the crew leaves. Note supply temperatures at several registers.
