Do I need a PE stamped HVAC design for a building permit in New Jersey?

Yes, under N.J.A.C. 5:23 (New Jersey Uniform Construction Code), commercial HVAC modifications, new multi-family developments, and extensive residential renovations requiring municipal permits require signed and sealed mechanical plans by a licensed NJ Professional Engineer (PE).

What is an ACCA Manual J calculation and why is it necessary?

Manual J is the industry-standard methodology for calculating heat loss and heat gain in a building. It accounts for ceiling heights, wall R-values, window orientation, and local outdoor design temperatures to prevent over-sizing or under-sizing HVAC equipment.
