Cloud-Based HVAC Design for Your Entire Engineering Team
From floor plans to load reports — design faster, stay under budget, and keep your whole team in sync. All in one platform.
Jon Rumohr, PE
Principal @ IGNYTE Design
“HVAKR does a fantastic job for us by helping us increase our efficiency and workflow for load calculations. It's straightforward and efficient. The single biggest impact is that the team actually wants to do the load calculations now. Before it was a burden.”

How it works
Three steps to a complete HVAC design
Platform Capabilities
Everything in one place
Navigate the entire mechanical design process — from basis of design through construction documents — without leaving HVAKR.
Real-Time Load Calculations
Change envelope properties and see updated loads, CFMs, and duct sizes instantly. What used to take days now takes seconds.
Integrated Duct Design
Dry-side design connects load calcs directly to duct sizing. Changes propagate automatically through your entire system.
AI-Powered Takeoffs
Accelerate space definition with intelligent area recognition. Walls, windows, and orientations are captured faster than ever.
Equipment Sizing
Select and size mechanical equipment with built-in libraries. Validated against ASHRAE standards for every component.
Real-Time Collaboration
Multiple engineers work on the same project simultaneously. Share, review, and coordinate without emailing files back and forth.
Professional Reports
Export construction-ready PDF and CSV reports. Load calcs, equipment schedules, duct layouts — all in one polished package.
Revit Plugin
Enhance BIM workflows with automated duct and pipe routing directly inside Autodesk Revit. No context-switching needed.
Basis of Design
Develop your project's basis of design within the same platform. Criteria, assumptions, and parameters all live together.
Agile Design
The architect changed the windows? No problem.
With a fully integrated platform, change any underlying criteria and see updated results across your entire design — loads, CFMs, duct sizes, equipment — all recalculated in real time.
Compliance & Transparency
The opposite of a black box
HVAKR is ASHRAE and ACCA compliant, backed by third-party audits. Our visual interface and schematic configuration make every design element transparent and trackable. No guessing, no hidden calculations.
ASHRAE Compliant
ACCA CompliantThermal load methodology
Incorporates thermal and shading properties of all envelope components using ASHRAE-approved methods.
Peak load analysis
Analyzes heat gain throughout the year to determine true peak load conditions for every zone.
Ventilation compliance
Calculates outdoor air requirements per ASHRAE 62.1 for proper indoor air quality.
Full audit trail
Every calculation parameter is visible and traceable. Review and verify at any step.
