Free 30-Day Trial Version

Are you interested in trying out Kwik Model with EnergyGauge Loads for FREE? Please do!!

Kwik Model is much easier, faster, and more intuitive than the other programs out there, however, that does not mean that it is “easy” to learn.  If you are already experienced with HVAC design, it will be much easier. No matter what, proficiency takes practice.  We highly recommend that you start with a very easy house, such as this one (click here to download) and shown in this video: 

Also, be sure to closely follow the step-by-step instructions, available on our download page (click here to download) Too many people start their first house as a really complicated actual project that they need to get down quickly and then get frustrated and nervous about the results.  I suggest at least three practice houses before doing your first “real” project.

Check out our user-run Facebook page.  It is a good place to ask for advice from other users.

We have lots of videos on our YouTube Channel: and some recorded training classes here:

 If you need tech support, feel free to email  We are a very small company but pride ourselves in our excellent customer support.

 I can also provide design assistance and personalized training, for very reasonable hourly rates.

 Have fun!

System Requirements:

Kwik Model with EnergyGauge Loads is a Windows based software. It may run on a Mac if you have a Windows emulator. KwikModel is a graphics-heavy program, similar to a video game. A “gamer” computer is ideal, but not mandatory. A good quality gamer laptop that will run Kwik Model really well can be found on line for under $400. Older computers with slower graphics cards and less than 4 GB of RAM will not get the full benefit of the 3D virtual environment. EnergyGauge USA is compatible with Windows 7, 8, 8.1 and 10 computers. Microsoft will no longer support Windows 7 on January 14, 2020 and we cannot ensure full functionality of the program on Windows 7 after that date.

Note: By requesting a license key for the trial version, you acknowledge that you have read and accepted the Kwik Model Trial Version license agreement, which can be downloaded HERE and the EnergyGauge license agreement HERE.
