FAQ

Manual J Calculation in North Dakota, answered.

What is a Manual J calculation?

Manual J is the ACCA procedure for calculating how much heat a house loses in winter and gains in summer, room by room. The result tells you how big the heating and cooling equipment needs to be. Most residential codes require it for new construction and many permits for replacements.

How much does a Manual J cost?

$100 per house for Manual J, Manual S and Manual D together. No subscription and no minimum order.

How fast do I get the report?

Usually 2–3 business days after we receive complete plans and specs.

Will the building department accept it?

Reports follow ACCA Manual J 8th Edition, Manual S and Manual D and use the plans you send. Acceptance is up to your building department; if plan review asks for corrections to our report, we revise it at no charge.

Do you work with builders and contractors on many houses?

Yes. Builders and HVAC contractors are our main customers. The price stays $100 per house for J, S and D, and repeat plans are kept on file.

What do I need to send?

Floor plans, elevations or orientation, the window and door schedule, insulation levels, duct location and the equipment you plan to install.
