Included with every Manual D

Manual T: where the air lands matters.

Included with every Manual D. Drafty corners, a cold spot over the bed and whistling grilles are usually air distribution problems. Manual T selects and places supply outlets and returns so the air actually mixes the room.

What it is

Manual T sizes and locates supply diffusers, registers and return grilles using manufacturer data for throw, spread, drop and sound.

It turns the airflow numbers from Manual D into a room that feels even from the doorway to the window. We run it in Wrightsoft, the industry-standard software for ACCA Manuals.

When you need it

Manual T is rarely the line item a permit asks for, but it is the one homeowners feel. It is most valuable in high-performance homes, tall ceilings, and rooms with large glass.

Requirements vary by jurisdiction. Send us the project address and we will tell you what your building department typically asks for.

Questions

Is Manual T extra?

No. Manual T is included with every Manual D we design.

Is Manual T required?

Rarely by code. It is a comfort and quality step, which is why we include it with the duct design.

Can you fix an existing drafty room?

Often, yes. Send photos, dimensions and the current register sizes.

Does it change my duct design?

Sometimes. Outlet choice and location feed back into Manual D, which is why the two are done together.
