Residential HVAC Design & Mechanical Plans for Florida Homes

Florida Premier Mechanical provides HVAC design and mechanical engineering services for residential projects across Florida, including custom homes, remodels, additions, and whole‑home system upgrades. We develop accurate load calculations, properly sized HVAC systems, and coordinated mechanical plans that support comfort, efficiency, and long‑term performance.

Our residential services are designed to streamline the design and permitting process by delivering clear, code‑compliant documentation, and practical system layouts tailored to each home. We work closely with architects, builders, and homeowners to ensure that equipment selections, duct routing, and system performance align with project goals, architectural intent, and the owner’s comfort expectations—all while maintaining full compliance with Florida building codes and energy requirements.

  • We deliver full ACCA‑approved Manual J, Manual S, and Manual D calculations for residential projects of all sizes. Each calculation is performed using industry‑standard methods and tailored to the specific construction details of your home.

    Manual J – Load Calculations

    We calculate precise heating and cooling loads based on insulation, windows, orientation, occupancy, and construction details. This ensures the system is sized correctly — not oversized, not undersized.

    Manual S – Equipment Selection

    We match the load results to properly sized HVAC equipment that meets manufacturer requirements and Florida Building Code.

    Manual D – Duct Design

    We design duct systems that deliver proper airflow, static pressure, and comfort throughout the home. Layouts include trunk lines, branch runs, grille sizing, and airflow balancing.

  • Our mechanical plans are fully coordinated and accepted by building departments across Florida. Each plan set includes:

    • HVAC equipment locations

    • Duct layouts and sizing

    • Return air pathways

    • Ventilation requirements

    • Condensate routing

    • Code‑required notes and details

    • Schedules and specifications

    These plans are designed to integrate cleanly with architectural and structural drawings, reducing field conflicts and change orders.

  • For custom homes and high‑performance builds, we provide detailed mechanical designs that prioritize comfort, efficiency, and long‑term reliability. We coordinate directly with architects, builders, and homeowners to ensure the HVAC system supports the home’s layout, aesthetics, and performance goals.

    This includes:

    • Zoned HVAC systems

    • High‑efficiency equipment options

    • Fresh air and ventilation strategies

    • Tight‑envelope home considerations

    • Mechanical room planning

    • Equipment clearance and serviceability

  • We provide HVAC design solutions for additions, renovations, and remodels where existing systems must be evaluated and integrated. Our services include:

    • Load impact analysis

    • System resizing

    • Duct modifications

    • Equipment upgrades

    • Code compliance updates

    This ensures the expanded home remains comfortable and efficient without overloading the existing system.

  • To complete your residential energy and load calculations accurately, we ask for the following:

    Project Information

    • Address
    • New construction, addition, or renovation
    • Conditioned square footage
    • Number of stories

    Building Details

    • Floor plans and elevations
    • Window and door schedule (sizes, types, U‑factor/SHGC if known)
    • Insulation values (walls, attic, floors)
    • Orientation (north arrow)

  • Your completed residential energy package includes:

    Energy Code Compliance Documents

    • Residential Energy Conservation Code Documentation Checklist
    • R405‑2022 Performance Report (or Prescriptive documentation if applicable)
    • Input summary checklist
    • Energy Performance Level (EPL) Display Card
    • Mandatory requirements summary

    Mechanical Calculations

    • Manual J Load Calculation (required for permitting)
    • Manual S Equipment Sizing (required for permitting)
    • Manual D Duct Design
    (required for permitting in most counties)

    All documents are prepared to meet Florida Building Code requirements and are ready for permit submission.

Florida Building Code Compliance

All residential HVAC designs meet the requirements of:

  • Florida Building Code – Mechanical

  • Florida Energy Conservation Code

  • ACCA Manual J/S/D standards

  • Local jurisdiction permitting requirements

Our documentation is clear, complete, and accepted by building departments throughout Florida.
