HVAKR

HVAKR is a cloud-based HVAC design platform with a Revit extension that covers basis-of-design, space takeoffs, load calculations compliant with ANSI/ASHRAE/ACCA Standard 183, equipment sizing, and duct system design in one visual workflow.

Mechanical engineering teams often juggle separate tools for load calculations, equipment selection, and duct layout. HVAKR consolidates that sequence into a single browser-based platform where changes to underlying criteria, such as window selections or airflow targets, propagate through loads, CFM values, and duct sizes automatically (HVAKR, 2026).

A Techstars portfolio company, HVAKR reports that teams using the platform complete designs up to ten times faster than with legacy desktop tools. Customer testimonials from firms like A3 Engineering and Jackola Engineering describe halved calculation time and reduced rework when architectural revisions occur (HVAKR, 2026).

Load calculations follow ANSI/ASHRAE/ACCA Standard 183, backed by third-party audits. The visual interface uses imported floor plans as a backdrop, so users make inputs spatially rather than in spreadsheets. Real-time results update as data changes, and PDF or CSV reports export directly from the platform (HVAKR, 2026).

Pricing starts at $100 per month for a solo Lite seat and $800 per month for a Professional team of three, with additional seats at $60 per month. Enterprise plans for teams over 20 include custom integrations, API access, and dedicated onboarding.

Pros and cons

Pros

  • Consolidates basis-of-design through duct sizing in one platform, eliminating tool-switching.
  • Real-time calculation updates make architectural revisions fast to absorb.
  • Visual floor-plan interface reduces input errors compared to spreadsheet-only tools.
  • Third-party audited ASHRAE/ACCA Standard 183 compliance.
  • Cloud-based with live collaboration; no desktop installation required for the web app.

Cons

  • Lite plan is limited to one seat and does not include duct sizing or collaboration features.
  • Enterprise pricing is custom; no published rate for large teams.
  • Revit extension capabilities may differ from the full web platform; confirm feature parity.
  • Teams must verify that local code requirements beyond Standard 183 are covered for their jurisdiction.

Key features

  • Visual floor-plan inputs: Import floor plans and make spatial inputs rather than working in spreadsheets or text fields.

  • Real-time load calculations: Heating and cooling loads update instantly when criteria change, following ANSI/ASHRAE/ACCA Standard 183.

  • Basis-of-design workflow: Centralized project assumptions flow through all downstream calculations and sizing.

  • AI-powered space takeoffs: Automated space detection and zoning from uploaded floor plans.

  • Equipment sizing: Select and size mechanical equipment within the same design flow.

  • Duct system design: Automatic duct sizing tied to calculated airflows and space zones.

  • Live team collaboration: Cloud-based project sharing for simultaneous editing across team members.

  • PDF and CSV reports: Export heating and cooling loads, ventilation summaries, and airflow data for deliverables.

  • Automatic design updates: Changing a window type, wall assembly, or airflow target cascades through the entire design.
