Engineering Design Assistance and Training

Hello!  My name is Russ King.  I am the designer of Kwik Model 3D.  I am a licensed Mechanical Engineer in three states (CA, NV, and HI).  I have over 30 years of experience doing residential HVAC design.  I ran two mechanical engineering departments that specialized in residential HVAC design and have trained hundreds of people how to design residential HVAC systems.  I even authored a book on the subject: HVAC 1.0 – Introduction to Residential HVAC Systems.  I also have a blog

I stopped accepting design work several years ago to pursue other interests (and because I got a little burned out on it, to be honest).  I am now offering engineering design assistance and training services ONLY to licensed users of Kwik Model 3D software for a reduced hourly rate. 

I can help you:

  • build the 3D model of the house
  • perform the heating and cooling load calculations
  • size the equipment
  • layout and size the ducts

I will send you the Kwik Model project files so that you can make any changes that you want.  I can also review your work and make suggestions.  After a project or two you will have much more confidence in the software and your own design abilities.  This can even be done using remote on-line screen sharing where we can discuss the project live and you can watch how I layout a system.

For more information, please contact

Important Disclaimer: This is not a mechanical engineering service. This is just design assistance and training.  I am not the engineer of record for your project.  I will not stamp your plans. (That costs a LOT more and can only be done CA, NV and HI.)  I am only providing you training and advice on how to use the Kwik Model software.  You are ultimately responsible for the performance of the design that you choose to install.
