I need a qualified HVAC designer to verify and document Manual J load calculations, Manual D duct layouts, and Manual S equipment selection for a single-family residence so I can demonstrate full compliance with the Florida Building Code – Residential submission ready. You will be working from accurate exterior elevations and an interior floor plan that already includes all room dimensions, window and door schedules, insulation specs, and orientation. Scope • Re-check the heat-gain / heat-loss numbers with Manual J. • Size and lay out the complete duct system per Manual D, showing trunk and branch sizing, CFM requirements, and friction rates. • Recommend properly matched equipment in line with Manual S and current FBC efficiency requirements. • Flag any conflicts with the code and suggest corrective options. Deliverables (PDF + native files) 1. Sealed or digitally signed Manual J report. 2. Duct design drawings with legend, balancing data, and static pressure calculations. 3. Manual S worksheet with model numbers and performance data at design conditions. 4. Summary letter certifying that the design meets FBC-R and ready for building-permit submission. Please indicate in your proposal which calculation software you prefer (e.g., Wrightsoft, CoolCalc, Elite) and your turnaround time.

I have experience preparing residential HVAC design documentation, including Manual J load calculations, Manual D duct design, and Manual S equipment selection for code-compliant permit submissions. I can review your architectural plans, verify the heating and cooling loads, design an efficient duct system with complete airflow and static pressure calculations, recommend properly matched equipment that complies with current Florida Building Code requirements, and deliver an organized permit-ready package with all supporting reports and drawings. I am comfortable working with industry-standard HVAC design software such as Wrightsoft, Elite, or CoolCalc, depending on your project requirements and local submission preferences. Could you confirm whether the jurisdiction requires a digitally signed/sealed package by a Florida-licensed professional, and what is the total conditioned floor area and project location? This will ensure the deliverables meet the exact permitting requirements from the outset.

Hello, I reviewed your requirements, and the primary challenge is ensuring the Manual J, Manual D, and Manual S calculations remain fully coordinated so the HVAC design satisfies Florida Building Code requirements and is ready for permit submission without inconsistencies between load calculations, duct sizing, and equipment selection. The verification should confirm airflow, static pressure, friction rates, and equipment performance while identifying any compliance issues before the documents are finalized for review. I have worked on HVAC design documentation and code compliance projects and can share relevant examples once we connect in chat. Best Regards, Atik
