FAQ
What is a Manual J Calculation?
Manual J is a residential load calculation method developed by ACCA. It determines the heating and cooling requirements of your home based on size, layout, insulation, windows, climate zone, and more. It ensures your HVAC system is properly sized — not too big, not too small.
Do I need this for a building permit?
Yes, many building departments in the U.S. require a certified Manual J report as part of the permit application, especially for new construction or major renovations. My reports are ACCA-certified and accepted across all 50 states.
What information do you need to start?
I only need the architectural plans of the house (PDF or DWG), which should include: The project address Construction details for walls, roof, and floor Room layout and dimensions
Can you also provide Manual S or Manual D?
Yes! I can perform Manual S (Equipment Selection) and Manual D (Duct Design) as additional services. Please message me before ordering if you need these.
What if my building is not residential?
Manual J is for residential buildings only. If your project is a small commercial building, I can perform Manual N calculations upon request. Please contact me first to discuss.
