ACCA Manual D

Right-D®

Manual D Duct Designs:

Right-D® is a fast, easy-to-use residential duct sizing and calculation software that takes full advantage of ACCA's and ANSI’s standard Manual D Method. A proper Manual D duct design with Right-D® will help to quickly find which fan, coil and filter combinations will work together to achieve optimal results and best suit you and your customer. Simply set your system’s external static and pressure drops, select your duct library, and draw your ducts where you want them. Or choose to utilize one of auto-draw systems. Right-Duct® will select the fittings, measure the actual and equivalent length of the runs and size, calculate the appropriate friction rate for each duct, as well as properly size the ducts for you. View overview video.

Features:

In conjunction with Right-Draw®, you may draw your duct design, or simply place the registers where you want them, and allow Right-D® to design your layout for you. Using both of these products together also allows the instant calculation of friction rates of each run with every change made in Right-Draw®. Right-D® features the complete ACCA fitting list, which can be modified and saved in libraries for re-use.

Use Right-D® to:

Automatically size your ducts and registers. This program will choose the right duct sizes for your project based on airflow, static pressure and user selected fittings.

Automatically reduce riser size for 3 or more floors.

Automatically place registers within a floorplan. Once your floorplan has been established in Right-Draw®, Right-D® will place your registers for you with the click of a button. Right-D® can also instantly connect branches to trunks to save you time.

Automatically add Flex End for sound attenuation. Once your main duct branches are set, easily add flex duct to each supply branch run.

Consider “What If” scenarios. Choose to change the filter pressure drop, or change the airflow or fan pressure and the entire system will instantly change to account for the alterations made.

Easily view ducts by system. Right-D® is color-coded to help define which system you are viewing.

Ensure a properly design system. Let Right-D® be your second set of eyes by highlighting fittings that do not fit together properly.

Benefits:

Right-D® is the ultimate Manual D design program for all skill levels. Simply set and save your preferences, draw your floor-plan with the help of Right-Draw®, and your duct design is practically done for you. If you wish to rely on your own design knowledge, you may also choose to design the system manually, and rely on the smart features if ever in doubt. 


Testimonials

Roquey from Integrity Comfort Solutions says,

"I have used Wrightsoft since the days of monochromatic screens and the spreadsheet-only format. I've attended several classes, been to the World Headquarters in Lexington, and even hosted training classes. The level of support is phenomenal. Both in the classroom, call in and email.

I've used the Right J, Right Draw modules extensively in the new construction markets not only for the purpose intended, but also to "value engineer" the materials selection process for my clients. I can't imagine a better product. The learning curve is pronounced and requires commitment on the part of the user, but with constant use it becomes almost second nature.

As a 40+ year veteran of our industry, I highly recommend this company."

Mike Douglas, from Advent Air Conditioning says,

"As a business owner, one of the things I like is that Right-Draw gives us a level of professionalism whether it’s a specialty home or a basic starter home. Within the past year, we have actually picked up new accounts because our customers were so impressed by the professionalism of our designs, particularly when we go up against contractors who are giving them what amounts to a crayon rendition on a napkin."

Bob Pietrangelo from Comfort Solution says,

"I’ve always been a proponent of proper sizing of air conditioning equipment. For a standard 3,000 square foot, 4 bedroom house, doing the load calculations manually would take many hours. Then I found Wrightsoft, and by using their Right-J and Right-D, I was able to produce load calculations and duct design in about an hour."

Al Gagne from Bayside Mechanical says,

On our Training:
"I've been to three of your trainings over the last 7 years and every time I go I learn something new. The class provides a thorough understanding of Right-Suite® Universal and helpful shortcuts so that I can continue to run my business effectively in this changing market."

On our Software:
"Wrightsoft’s Right-Suite® Universal has helped us to turn bids around faster, especially for custom home builders. I can simply import the AutoCAD building plans as a layer in the program, trace to complete the load calculations and add my ducts to the design, saving me a considerable amount of time. The full design and calculation is then saved in the AutoCAD file as another layer."
