Partner questions, answered.
Is there a contract?
No. Partners order per house at $100 for J, S and D. There is no subscription, no minimum volume and no exclusivity.
Can you keep our standard plans on file?
Yes. For repeat plans we keep the model and only change what differs: orientation, windows, options and the equipment.
Can the report show our company name?
Each report names the project, the builder or contractor who ordered it and the preparer. Ask us if you need a specific format for your jurisdiction.
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.
