Manual J Calculation in Wood Dale, 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.
Do you need to visit the site in Wood Dale?
No. We work from your plans and specifications, so a project in Wood Dale is handled remotely like any other. If a detail is missing, we ask before we start.
What climate zone is Wood Dale in?
Wood Dale is in DuPage County, which is assigned to IECC climate zone 5A. Your local building department’s adopted code edition is what counts, and we use the design temperatures for the project location.
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.
