Manual T - Air Distribution Basics

Manual T - Residential & Commercial

From the room-by-room loads and cfm requirements, you can determine how to distribute the air in the room so that you get enough to meet the needs (the higher of the heating and cooling cfm requirements from Manual J).

The right termination (the grille that you see from inside your house) can make dramatic differences in how air moves around the room. Some terminations are more effective than others, for certain situations. We’ll make sure your terminations match the needs of the home.

Manual T shows you how to prevent drafts and stagnant air problems caused by improper sizing or incorrect equipment selection.
