For Technicians, Balancers & Engineers
Release Candidate
Goodale HVAC Fieldbook connects serious HVAC engineering calculations to controlled commissioning projects, phased measurements, design tolerances, deficiencies, instruments, approvals, and customer-ready reporting.
Built for mechanical rooms, rooftops, job trailers, balancing routes, and engineering review. Core workflows work offline, no account is required, and project records stay on your device.
Run duct traverses, pitot airflow, outlet percent balance, total external static, ACH, K-factor flow, outside-air percentage, and mixed-air checks.
Solve tons, GPM, BTU/hr, and delta T, then check water static pressure, pump head, pipe velocity, pipe volume, valve Cv flow, and pump power.
Solve air states, cooling-coil performance, fan and VFD predictions, electrical load, refrigeration temperature differences, efficiency, gas input, and engineering conversions.
Organize projects by customer, site, area, system, equipment, and test point. Capture initial, adjusted, and final readings with clear units, tolerances, timestamps, and technician context.
Track corrective actions, verification notes, instrument calibration, evidence-driven readiness, preparer and reviewer details, customer approval, and a local signature.
Export a print-ready PDF closeout package or analysis-ready CSV with systems, test points, design-versus-actual results, deficiencies, instruments, notes, approvals, and linked calculations.

Dark and light appearances support mechanical rooms, rooftops, and office review.
No advertising, third-party tracking, or Goodale Studios job-data server.
Frequently Asked Questions
Include your device model, iOS or iPadOS version, Goodale HVAC Fieldbook version and build, the calculator or project screen you were using, selected units, the steps immediately before the issue, and the exact error message. Redact customer names, site addresses, company-confidential details, signatures, and report content whenever possible.
No. The current release has no Goodale HVAC Fieldbook account or login, and core calculators, projects, measurements, deficiencies, instruments, notes, history, backups, and report generation work offline. Internet access is needed only when you choose to open an external web page or send content through another service.
They are stored locally on your device. Goodale HVAC Fieldbook does not provide cloud sync or a Goodale Studios backup server. Apple device backups may include app data depending on your settings, and you can create an app-generated project backup from Settings.
Create or open a project, make it active, run the calculator, then choose Save to Project. Select the relevant system, equipment, test point, instrument, and notes where applicable. The complete inputs, formula, result, units, and timestamp remain linked to the project.
Open Projects, choose a project, review its systems, readings, deficiencies, instruments, sign-off, notes, and linked calculations, then use the report export. Select PDF for a print-ready closeout package or CSV for analysis and record transfer.
Goodale HVAC Fieldbook has no developer-operated recovery service. Review deletion confirmations carefully and export important reports before removing records or deleting the app. Recovery may be possible only through an Apple device backup that contains the app data.
