I will do acca manual j d s load calculation with duct design for permit

Complete residential HVAC design documentation — Manual J load calculations, Manual S equipment selection, and Manual D duct design with layouts. Everything is delivered as permit-ready PDF reports.

Manual J calculates your home's heating and cooling loads. Manual S selects the correctly sized equipment based on those loads. Manual D designs the duct system so airflow reaches every room properly. Cities require these for permit approval.

Floor plans (PDF or CAD), the property's city and state, ceiling height, and insulation/window details if you have them. The more detail you share, the more accurate the calculations.

All work follows ACCA standards, which are accepted for permits across the USA. Local amendments can vary, so I recommend confirming any special requirements with your local building department.

I don't provide engineering stamps. If your jurisdiction requires a stamp, a licensed engineer in your state will need to review and stamp the drawings.

Yes — USA residential projects are my specialty, and all calculations follow ACCA standards used for US permits.

Unlimited. I'll revise the calculations and drawings until you — and your permit reviewer — are fully satisfied.

Yes, 2-day rush delivery is available as an extra. For urgent permit deadlines, message me before ordering so I can confirm the timeline.
