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.

HVAKR cuts through a lot of the tedious work of looking up standards and jumping between the various programs that one would use when working on HVAC&R projects by having them integrated all into the same program along with templates for common project types.

The intuitiveness of the program makes the program very easy to start using with little to no experience. The program actively updating the project whenever there is a change made so it is reflected in every part of the project. The number of features also makes the program very nice to use being able to complete entire projects in a single application.
