Air Conditioning Load Calculation in Maine, answered.
Why not just use square feet per ton?
Rules of thumb ignore windows, orientation, insulation and climate. Two houses with the same floor area can need very different equipment. An oversized AC short-cycles, removes less humidity and costs more to buy and run.
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.

Your next permit, sized right.
