Modifying HVAC Ductwork, Equipment Placement, or Airflow Paths

When HVAC Systems Are Modified

HVAC ductwork, equipment placement, or airflow paths are modified when interior layouts change, rooms are added or reconfigured, or existing systems no longer distribute air effectively. These changes can affect comfort, efficiency, pressure balance, and system performance and must be evaluated to ensure proper operation and safety.

Permitting and Licensed Trade Requirements

In Florida, HVAC work must be performed by a properly licensed mechanical contractor and typically requires building permits and inspections. Modifying ductwork, relocating equipment, or altering airflow paths must follow approved plans that address equipment sizing, duct routing, clearances, and airflow requirements. Inspections verify compliance with applicable codes before systems are placed into service.

General Contractor Oversight and Coordination

While HVAC work must be completed by a licensed mechanical contractor, the licensed general contractor remains responsible for the project as a whole. This includes coordinating permitted scope, sequencing HVAC work with other trades, scheduling inspections, and ensuring all work complies with approved plans and code requirements. If inspections identify deficiencies, corrections are coordinated with the licensed HVAC contractor and re-inspections are scheduled to prevent delays or compliance issues.
