The problem behind Goodale HVAC Fieldbook
A field number becomes valuable only when someone can explain where it came from, which system and test point it describes, what design value and tolerance apply, which instrument was used, and what happened next. Goodale HVAC Fieldbook is designed around that complete evidence trail instead of treating a calculator result as the end of the work.
Goodale HVAC Fieldbook connects 29 field calculations with controlled commissioning projects, phased readings, evidence-based readiness, signed closeout, and professional reports.
Goodale HVAC Fieldbook is designed for HVAC technicians, TAB specialists, engineers, commissioning providers, and field teams that need measurements, tolerances, deficiencies, instruments, and approvals to stay together. The goal is not to add another screen to the day; it is to make the complete decision or experience easier to understand from beginning to end.
One connected experience beats a pile of separate tools
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.
- TAB and balancing depth: Run duct traverses, pitot airflow, outlet percent balance, total external static, ACH, K-factor flow, outside-air percentage, and mixed-air checks.
- Hydronic engineering: 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.
- Psychrometrics and diagnostics: Solve air states, cooling-coil performance, fan and VFD predictions, electrical load, refrigeration temperature differences, efficiency, gas input, and engineering conversions.
- Controlled commissioning projects: 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.
- Deficiencies and closeout: Track corrective actions, verification notes, instrument calibration, evidence-driven readiness, preparer and reviewer details, customer approval, and a local signature.
The details that earn a place in the routine
Match the formula to the field condition: Confirm that the calculator's relationship, units, fluid or air assumptions, instrument method, and required precision apply to the system being measured.
Make the project active before saving: A result without the correct project, system, equipment, test point, and instrument becomes difficult to defend later. Check the active-project context before recording professional evidence.
Treat the KPI as a review prompt: Commissioning-readiness visibility can reveal missing measurements, failed tolerances, unresolved deficiencies, expired calibration, or incomplete sign-off, but it does not replace professional judgment or project requirements.
Useful promises need honest boundaries
Goodale HVAC Fieldbook 1.0 build 4 is waiting for Apple App Review. It is not publicly downloadable until Apple approves the release.
Goodale HVAC Fieldbook 1.0 build 4 is waiting for Apple review and is not presented as a public download until approval. Core records stay locally on iPhone and iPad, no Goodale Studios account is required, and exports leave the app only when the user chooses a destination through Apple's share sheet.
The result that matters
The workflow succeeds when calculations are technically appropriate, phased readings and tolerances are reviewable, unresolved work is visible, instruments and approvals are documented, and the final handoff explains what was measured without overstating what the app proves.
That is the standard behind Goodale HVAC Fieldbook: a focused app should leave the next decision clearer, the completed work or play session more satisfying, and the value easier to explain than it was before the first tap.
