Professional HVAC Field Engineering for iPhone
Coming Soon
HVAC Toolbox Pro is built for the moment a reading has to become a decision, a job record, and defensible professional evidence. Run the calculation, save it to the active customer and system, complete the quality checks, and export the handoff.
Core calculators, jobs, notes, history, and reports work offline. No account, advertising, or third-party tracking SDK is required.
Average duct traverses, calculate pitot airflow, compare outlets with design, profile total external static pressure, check ACH, use K-factors, and preserve the readings with the job.
Work from tons, GPM, BTU/hr, or delta-T, then handle water head, static pressure, pump TDH, pipe velocity, pipe volume, valve Cv, and hydraulic power from the same focused tool library.
Use airside loads, airflow and duct area, fan laws, belt-drive speed, electrical power, superheat and subcooling math, capacitor tolerance, efficiency, gas input, and engineering unit conversions.
Choose an active company job before calculating. Saved results automatically retain the customer, site, system, technician, scope, and field context that make the number useful later.
Job status, standardized quality checks, and a field-readiness KPI make open work understandable without replacing the technician's judgment or the project requirements.
Generate a branded PDF for customers, supervisors, commissioning agents, or the project file, or export CSV when readings need to move into a spreadsheet or company archive.

Official Product Facts
Run 25 HVAC and TAB calculations, keep results attached to the correct job, track field readiness, and export professional PDF or CSV reports—even when the jobsite is offline. It is currently in development, so features, compatibility, and release timing may change before publication.
How It Works
Filter the workbench for Technician, Balancer, or Engineer workflows.
Favorite frequently used tools and keep local calculation history and field notes.
Create company jobs with customers, sites, systems, technicians, scope, status, and checklists.
Work without a network connection and export only when you choose a destination.
Verify every result against project documents, manufacturer data, instruments, codes, standards, and qualified professional judgment.
Frequently Asked Questions
Include your iPhone model, iOS version, app version and build, the calculator or job screen you were using, the inputs you entered, the expected result, the result shown, and the steps immediately before the issue. Remove customer and site information whenever it is not required to reproduce the problem.
No. Core calculators, company jobs, notes, saved results, history, checklists, KPI summaries, and report generation work locally without a Goodale Studios account. A connection can still be needed for App Store services or for a destination you choose when sharing an export.
Open Jobs, create or select the job, and make it the active field job. When you save a supported calculation, HVAC Toolbox Pro links the result to that active job so its customer, site, system, and scope remain with the evidence.
They are stored locally in the app's private container on the iPhone. Goodale Studios cannot see or remotely restore that database. Use appropriate device backups and export any professional records you are required to retain.
No. The tools apply common field relationships to the values you enter. Confirm units, instrument requirements, project documents, manufacturer data, applicable codes and standards, and qualified professional judgment before acting on a result.
The app creates the selected report locally, then opens Apple's share sheet. Review the company branding, job details, readings, checklist state, notes, and recipient before sending or saving the file.
