Why Manual J

Square feet per ton is not a calculation.

Two houses with the same floor area can need very different equipment. Windows, orientation, insulation, air leakage, duct location and climate change the load. Codes require ACCA Manual J and Manual S because rules of thumb usually oversize.

Oversized equipment short-cyclesMore wear, more noise, worse humidity control and a higher price for the unit.

FAQ

Air Conditioning Load Calculation in Lake Santeetlah, 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.

Do you need to visit the site in Lake Santeetlah?

No. We work from your plans and specifications, so a project in Lake Santeetlah is handled remotely like any other. If a detail is missing, we ask before we start.

What climate zone is Lake Santeetlah in?

Lake Santeetlah is in Graham County, which is assigned to IECC climate zone 4A. 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.
