About this Gig
Are you looking for official ACCA-compliant Manual J, Manual D, and Manual S calculations to secure building permit approval or size your HVAC equipment properly? Oversized or undersized equipment leads to high energy bills, poor humidity control, and municipal plan check rejections.
I perform precise, software-backed HVAC load calculations and system sizing in strict accordance with ACCA standards, IECC, and local energy codes.
What Is Included in the Reports:
- Manual J (Heating & Cooling Load Calculations): Room-by-room load calculations based on climate location, thermal envelope, insulation R-values, and window solar heat gains.
- Manual S (Equipment Selection): Verification of heat pump, air conditioner, or furnace manufacturer capacity specs matched to calculated loads.
- Manual D (Duct System Design): Airflow CFM distribution, duct sizing (supply/return), and static pressure calculations for balanced comfort.
Why Order This Gig?
- Approved Software: Generated using industry-standard ACCA-approved software (Wrightsoft / Elite RHVAC).
