Hvac manual d

 · Manuals J, D and S were developed by engineers at the Air Conditioning Contractors of America (ACCA) to implement universal standards and best practices for the design and installation of residential HVAC systems. Manual J and Manual D are recognized throughout the country, touted by the U.S. Department of Energy and required by most building codes. Our technical manuals cover the complete gamut of design, installation and maintenance for residential and light commercial HVAC systems. ACCA technical manuals are taught by the leading industry schools and vocational programs. Many of our manuals are approved as ANSI standards, and many are referenced inside building codes nationwide.  · Manual D is the industry standard for sizing home HVAC return and supply duct registers. Manual D duct design distributes the correct amount of heating and cooling to each room based on the Manual J load calculation results.

Manual J (Residential Load Calculations) Manual J is the first step in the design process of a new HVAC.
