Mechanical Engineers On Tap
HVAKR is more than software. Every plan includes support from mechanical engineers who design HVAC for a living, so when a hard load-calc or system-selection question comes up, you get an answer from someone who has solved it before. Where other tools offer software support, HVAKR offers engineering support.

Fast, human product support and onboarding that gets your whole team productive in a day.
Expertise included
Mechanical engineering help comes with your subscription: no consulting contract and no extra fee.
