ASHRAE Duct

Right-CommDuct

ASHRAE Commercial Duct Designs:

Right-CommDuct is a fast, easy-to-use commercial duct sizing and calculation software that takes full advantage of ASHRAE’s precision measurements and duct fitting database. View overview video.

Features:

With Right-CommDuct, compute duct and fitting size based on air flow with appropriate velocity limits, and let the software calculate the required fan pressure and total air flow for you. Using the complete built-in ASHRAE database of ducts and fittings allows for accurate commercial duct design to ensure the proper product for the job.

Right-CommDuct has an additional special calculation mode, Existing System, in which you specify the available fan pressure, draw an existing real world duct system, and then specify the actual duct sizes. Right-CommDuct calculates the air flow that will actually come out of each register! You can compare this to the correct air flow, as calculated and diagnose problem systems. Using this approach, you can see what it will take to fix a bad system. When the design air flows match the (modified) actual air flows, you're in business.

Use Right-CommDuct™ to:

Calculate duct sizes based on Equal Friction, Modified Equal Friction, Static Regain, or existing system. More sophisticated than other duct sizing methods, Right-CommDuct will calculate the pressure needed to achieve the targeted Friction Rate, rather than manually readjusting the static pressure to achieve it.

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

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

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

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

Automatically size registers.

Automatically layout simple designs.

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."

Mike Truitt Resnet Rater from This Efficient House says,

“Hands down, the best tool for the job. Our HVAC partners love the 2-line mode drawings, and the export to REM/Rate module saves me at least 2 hours per project! That's a real game changer for us in terms of billable hours and revenue. Mike (sales) and Donald (tech support) have been there for us for over 10 years! Keep up the good work and thanks again guys. - Just another loyal happy customer.”

Jim Heinz President of Heinz Air Conditioning and Heating, Inc. says,

“We are primarily a residential replacement air conditioning and heating company in Clearwater, Florida.  We found a serious issue with improperly sized air conditioning systems in existing homes that was causing issues with humidity, or lack of cooling.  We have used Manual J for over 30 years, but due to the time-consuming process of entering information manually, it was not done unless we had a consumer complaint.  We partnered with Wrightsoft over 15 years ago and can now do a Manual J Load Calculation in less than 30 minutes. Wrightsoft is always there for us, with tech support staff that answers the phone quickly, and offer advice when needed.  There is also a library of how to videos available 24 hours a day on their website. Wrightsoft has continued to be the best option for us for Manual J load calculations.”

Tim Kohut Director of Sustainable Design, National Community Renaissance says,

“I reached out to technical support [to complete an advanced task].  [Technical support] responded within an hour or two, guided me through the process, and even QC’d my spreadsheet (making corrections needed).  I was really impressed… I’ve found that my questions are always answered, usually within hours, and there’s never an attempt to dodge an issue. Wrightsoft’s responsiveness on the support side is what truly sets you apart.  Your team has made my life easier and using RSU has become an integral cornerstone to the work I do guiding our teams in the design and construction of high performance, soon to be ZNE affordable housing.”

Steve Paxton from Air-Dynamics says,

“I've been using Wrightsoft since the late 80’s. Public Service Company in Oklahoma's "Good Cents" program required an ACCA Manual J load calculation and ACCA Manual D duct design to qualify as a "Good Cents" structure. As long as the information is entered correctly, Wrightsoft takes all of the guesswork out of the equation. It has given me peace of mind and keeps our quality of installation above the rest. I can't imagine doing an install without it, it's as important to us as the rest of the tools on our trucks.”

Tom Tumminelli from Brothers Plumbing, Air & Electric says,

“The Wrightsoft experience has been great from the beginning to end.  Their support staff are patient and professional.  Proper equipment sizing is imperative regarding our customers comfort. We have been able to provide our customers with accurate professional data to backup our proposals awarding us multiple projects over our competitors. Well worth the investment of time and money.”
