Available Now on the App Store
Goodale’s HVAC Fieldbook executes witnessed functional-performance tests and connects their expected-versus-observed evidence to phased measurements, design tolerances, deficiencies, calibrated instruments, approvals, and customer-ready reporting.
Check the official store listing for current download and in-app purchase terms. Availability can vary by device and region.
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.

Start with AHU, VAV, or hydronic pump procedures—or build your own. Verify prerequisites, execute ordered commands, and capture the actual system response, result, technician, witness, notes, and timestamp.
See accepted, failed, blocked, not-run, and not-applicable states clearly. Unverified prerequisites, incomplete required steps, failures, and blocks hold project closeout automatically.
Organize projects by customer, site, area, system, equipment, and test point. Capture initial, adjusted, and final readings with units, tolerances, timestamps, and technician context.
Use 29 airside, hydronic, psychrometric, refrigeration, electrical, fan, pump, efficiency, and conversion tools—including traverses, pitot airflow, total external static, tons/GPM, water pressure, and valve Cv.
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 functional-test prerequisites and steps, systems, readings, deficiencies, instruments, approvals, and linked calculations.

Official Product Facts
A professional offline commissioning fieldbook for HVAC technicians, TAB specialists, commissioning providers, and engineers—with witnessed functional testing, controlled project evidence, KPI readiness, signed closeout, and 29 supporting calculators. Goodale’s HVAC Fieldbook 1.0 is available now for iPhone and iPad on the Apple App Store.
How It Works
Role filters surface the right tools for a balancer, engineer, or technician.
Search, favorites, and recent results keep common calculations close.
The commissioning-readiness KPI is calculated from measurements, functional-test acceptance, deficiencies, calibration, and required sign-offs.
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, Android, iOS, or iPadOS version, Goodale’s HVAC Fieldbook version and build, whether you installed from Google Play or the App Store, the calculator or project screen, selected units, 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’s HVAC Fieldbook account or login, and functional tests, 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.
Records are stored in the app’s private local storage, not a Goodale Studios cloud service. On Android, automatic cloud and device-transfer backups are disabled: use Settings → Export Workspace Backup, save the JSON file securely, and use Settings → Import & Merge Backup to select a compatible Android backup. Import merges records; it is not cloud synchronization. On iPhone and iPad, Apple device backups may include app data depending on your settings, and an app-generated backup is available in Settings. Android and Apple backup formats are not interchangeable.
From a fresh installation, open Projects → Load Sample Project, then open the sample project. It contains fictional commissioning records for exploring functional tests, measurements, deficiencies, readiness, sign-off, and report exports. No account, access code, or downloaded customer project is required. Sample records are editable demonstrations, not certification of a real installation. Normal closeout requirements still apply.
Open a commissioning project and add a functional test from the AHU, VAV, hydronic pump, or custom template. Confirm each prerequisite, then record the commanded condition, expected response, actual observed response, result, technician, witness, notes, and timestamp for each step. Required incomplete, failed, or blocked work will hold closeout.
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.
