HVAKR is a browser-based HVAC design platform for mechanical engineers that turns uploaded floor plans into spaces, ASHRAE and ACCA load calculations, airflow, and client reports, with gbXML export on team plans.
Load calculations still stall when the floor plan changes and the spreadsheet does not. HVAKR is a cloud HVAC design tool for mechanical teams: you upload the plans, it scans spaces, picks a weather station from the project address, and builds a basis of design you can edit.
Space defaults come from ASHRAE 62.1, and assemblies can start from ASHRAE 90.1 and 62.1 tables or a saved firm template, filtered by climate zone and standard year. The public API describes load calculations with the ASHRAE radiant time series method. Change a design temperature, a wall, or a ventilation rate and the loads recalculate. HVAKR says that update shows up in about 100 milliseconds.
Reports include load summaries, a basis of design, a residential HVAKR J report, ASHRAE 62.1 ventilation documents, a canvas drawing, and a mechanical specification as a Word file. Team and Enterprise can also export gbXML and raw JSON. The API can create and update a project from Revit. The product pages do not list an IFC export.
Nothing is installed for the web app, and Solo is a single named login. Team seats float and can be reassigned, from 3 up to 20, and at 20 or more HVAKR points you to Enterprise. Support is described as mechanical engineers in project chat, email, or a video call, with an average response they put at about 37 minutes.
HVAKR vs Revit: HVAKR is a cloud HVAC platform for floor-plan takeoff, ASHRAE and ACCA load calculations, and client-ready reports in the browser. Autodesk Revit is full BIM authoring for coordinated multidisciplinary models. Many teams keep Revit as the model of record and use HVAKR for loads and basis-of-design work; HVAKR documents public API and Revit endpoints on api.hvakr.com that create and update projects from Revit data.
Pros and cons compared with Revit: HVAKR recalculates loads quickly in the browser, ships ASHRAE-oriented defaults, and publishes HVAC reports without a separate spreadsheet stack. Tradeoffs include no ongoing free plan, Team-tier requirements for gbXML export and shared libraries, and Revit remaining the hub for non-HVAC coordination and full BIM production.

Pros and cons
Pros
- Solo is a published $240 a month, with a 14-day trial, and no install.
- Team and Enterprise can hand gbXML to an energy model.
- Extra AI credits are a published $10 per 1,000, without changing plans.
- Focused HVAC load and takeoff workflow complements Revit rather than replacing full BIM authoring.
Cons
- There is no ongoing free plan. Solo is one seat only.
- gbXML, shared projects, and the extra cloud connectors for teams start at the Team price, $960 a month for 3 seats.
- Enterprise, including SSO and the API integrations, is a quote and starts being the recommended path at 20 seats.
- Revit remains the usual model of record for multidisciplinary BIM; HVAKR connects through API workflows instead of replacing Revit.
Key features
Floor-plan takeoff: Upload plans. HVAKR scans spaces with OCR and AI, selects a weather station, and drafts the basis of design.
Standards libraries: ASHRAE 62.1 space types, plus ASHRAE 90.1 and 62.1 tables or your own wall, space, and schedule templates.
Live loads: Heating and cooling loads and airflow update when inputs change. The API documents the ASHRAE radiant time series method.
Reports: PDF loads report, basis of design, residential HVAKR J, canvas drawing, and ASHRAE 62.1 IAQP ventilation. Mechanical specification exports as DOCX. Several tables also export as CSV.
gbXML: Team and Enterprise can export building geometry and constructions as gbXML for energy-modeling tools. Raw JSON is on the same plans.
Revit API: Public API endpoints create a project from Revit and update a project from Revit. No IFC export is listed in the report docs.
AI credits: Solo 1,500 per month, Team 10,000 plus 1,000 per extra seat, Enterprise 100,000 plus 2,000 per extra seat. Extra credits are $10 per 1,000.
Team admin: Floating seats, shared libraries, project history, invoice payment, and required MFA. Enterprise adds SSO, SCIM, audit log, and a 24-hour support SLA.

$960.00
USD $960 per month at the 3-seat starting point on the vendor site. Scales to 20 seats. Extra seats are $80 per month each. Includes 10,000 AI credits per month plus 1,000 per extra seat.
HVAKR Solo (yearly, shown per month)
per year (12 mo)
$2,400.00
Yearly toggle shows $200/mo with the $240/mo price struck through. FAQ says yearly billing gives 2 months free, so this is $2,400 per year. Ask about the checkout total.
HVAKR Team (yearly, 3 seats, shown per month)
per year (12 mo)
$9,600.00
Yearly toggle shows $800/mo versus $960/mo monthly, for 3 seats. That is $9,600 per year if the monthly equivalent holds for 12 displayed months with 2 months free. Extra seats are $67 per month when billed yearly. Ask about the invoice.

Frequently asked questions
How much does HVAKR cost?
On hvakr.com/pricing as of 30 Sep 2026, Solo is $240 per month for one seat, or $200 per month when billed yearly. Team starts at 3 seats for $960 per month, or $800 per month on the yearly toggle, and extra seats are $80 per month or $67 per month on yearly billing, up to 20 seats. Enterprise is custom and is the plan HVAKR points to at 20 seats or more. Yearly billing is described as 2 months free. Prices are US dollars.
Does HVAKR have a free trial?
Yes. Solo includes a 14-day free trial and Team includes a 30-day free trial. There is no ongoing free plan. The terms of service also say refunds are available within 7 days of purchase, via support@hvakr.com. Subscriptions renew unless cancelled, and billing is managed at app.hvakr.com.
Does HVAKR work on Mac or only in the browser?
The pricing FAQ says HVAKR is fully cloud-based and there is nothing to install, sync, or maintain. That covers a desktop browser on Mac or Windows. A separate Windows or Mac application is not listed. The public API does include endpoints to create and update a project from Revit, so a Revit user on Windows can connect, but the design workspace itself is the website.
Does HVAKR export IFC, gbXML, or Revit files?
gbXML export of geometry and constructions is documented for Team and Enterprise, aimed at energy-modeling tools. Reports also download as PDF, CSV, DOCX for the mechanical specification, and raw JSON on Team and Enterprise. The report docs do not list IFC. The API can create a project from Revit and update a project from Revit, which is a sync path rather than an IFC handoff.
What is the difference between HVAKR Solo and HVAKR Team?
Solo is one seat at $240 a month, with personal templates, loads, PDF and CSV reports, and 1,500 AI credits. It cannot add a second login. Team starts at three seats and $960 a month and adds shared libraries, floating seats, organization-wide sharing, project history, MFA, invoice payment, and gbXML. Enterprise, from 20 seats, adds SSO, SCIM, an audit log, and 100,000 AI credits a month, at a quoted price.
Who is HVAKR for, and which standards does it use?
HVAKR is aimed at mechanical design teams doing commercial and residential HVAC. The homepage pulls space types from ASHRAE 62.1 and lets you start from ASHRAE 90.1 and 62.1 tables. The API describes loads with the ASHRAE radiant time series method, and plan names say ASHRAE/ACCA load calculations. A residential project can produce the HVAKR J report. Commercial projects can produce an ASHRAE 62.1 IAQP ventilation report.
Is HVAKR reliable for professional work?
Yes, HVAKR is aimed at professional mechanical design teams that need ASHRAE and ACCA load calculations with documented reports. HVAKR's pricing page shows a G2 rating of 4.7 out of 5, states that projects are saved and backed up in the cloud, and the homepage describes support from mechanical engineers via project chat, email, or video.
