The simplicity. The learning curve was relatively low due to the organized layout and distinct sections with a button prompt to move on to the next section, in addition to the organizer tree to go to any point at any time.

HVAKR is highly accessible for students, allowing them to progress from creating a new account and project to developing a functional building model in a short amount of time. The workflow is intuitive, which makes it especially suitable for learning how to perform load calculations. In our HVAC&R course labs at Cal Poly, students construct a model based on plans—defining spaces, the building envelope, zoning, and a basic system configuration—and are able to produce clear heating and cooling load results without spending the entire lab session struggling with the interface.

I use HVAKR for HVAC heat and AC calculations and duct design. It really streamlines the process compared to older software I've reviewed. What stands out most for me is the ease of use and particularly their customer service. The chat is always available, and they take the time to have meetings, training you on how to use the product and answering any questions without making you feel rushed or like you're annoying them. They genuinely want you to be successful with their software and are always there to support you in this function. Also, the initial setup was a breeze, as it's a web-based software with no setup required - just go to the website, create an account, start calculating, and you're done.
