Aug 25, 2010 . Not so many, however, know about the missing links – Manual S and Manual T. If you want a properly designed HVAC system, you have to go through the whole process in all four protocols: J, S, T, and D. (It’s easy to remember the order. As a friend of mine says, first J, then STD.) Here then is a brief description of each manual.

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.
Most permit offices require all new residential and multifamily homes must demonstrate compliance with ACCA Manual J, S & D. Additions and alterations may also require code compliance if the mechanical contractor is installing new heating and cooling equipment.
ACCA’s Manual J even calculates the amount of heat and humidity that each occupant of the house will add to the interior of the home. Whole House or Block HVAC Load Calculations provide the heating and cooling loads for the entire home.
Due to the ever growing presence of new building materials, advanced insulation systems, and efficient ventilation systems, it’s impossible to use rule-of-thumb sizing methods and consistently achieve accurate and energy saving results. ACCA’s Manual J is the first step in the design process of a new heating and air conditioning system.
One of the biggest lessons I’ve learned is that HVAC design is a lot more than Manual J. Most HVAC contractors, home energy raters, and others in this field know about Manual J. Many people even know about Manual D, which describes how to design the duct system. Not so many, however, know about the missing links – Manual S and Manual T.
Manual D works in conjunction with the other manuals to provide proper design, sizing, and installation of residential duct systems. After you have determined the heating and cooling loads (Manual J), selected the right HVAC equipment (Manual S), and figured out how to distribute the air (Manual T), you can now design the duct system (Manual D).
After you have determined the heating and cooling loads (Manual J), selected the right HVAC equipment (Manual S), and figured out how to distribute the air (Manual T), you can now design the duct system (Manual D). Ductwork design is extremely important to prevent air and energy leaks, in addition to humidity and moisture problems.
This manual, combined with the load calculations from Manual J, gives the technician the technical information for selecting the proper system for your home, whether it’s an air conditioner, heat pump, furnace or boiler. Manual T has to do with your HVAC’s air distribution.
