HVAC Duct Pressure Test Inspection

It covers the full pressure test workflow for duct leakage verification: test identification, duct system details, pre-test readiness, test setup, leakage results, and final sign-off. The template is built to record both the measured leakage rate and the allowable limit so acceptance is clear. It also captures visible leaks, deficiencies, and retest decisions.

Use it when a duct system must be pressure tested before concealment, commissioning, or turnover, or when a specification requires documented leakage verification. It is especially useful after installation of supply, return, or exhaust ductwork and before insulation, ceiling closure, or equipment startup. If the work does not involve a pressure test or leakage acceptance, this template is not the right fit.

A qualified inspector or commissioning representative should complete it, with the contractor representative present when required by the project. The person running the test should understand the approved test plan, the test apparatus, and the acceptance criteria. If lockout-tagout or energized equipment hazards are present, the responsible competent person should control the work area.

It is typically performed once per duct section or system test event, not as a recurring daily inspection. Larger projects may use it multiple times as different zones or branches are completed and tested. If a retest is required after repairs, the same template should be reused to keep the record consistent.

Yes, it is structured to support SMACNA-style duct leakage testing documentation and can be paired with project specifications or manufacturer procedures. It also helps document general safety and quality expectations that often sit alongside HVAC testing on commercial projects. If your project references other acceptance criteria, you can edit the allowable leakage fields to match them.

Common mistakes include failing to identify the exact duct section tested, leaving the test pressure or allowable leakage blank, and not recording ambient conditions or calibration status. Another frequent issue is documenting only a pass/fail result without noting where visible leaks were found. The template is designed to prevent those gaps by prompting specific, observable entries.

Yes, the structure already supports supply, return, and exhaust duct systems, and you can add project-specific fields for zone, floor, or air handler association. You can also tailor the acceptance criteria to the project specification or the applicable leakage class. If your team needs more detail, add fields for duct insulation status, access panel count, or repair verification.

An ad-hoc checklist often misses the details needed to defend acceptance later, especially when leakage is close to the limit or a retest is required. This template creates a consistent record of what was tested, how it was set up, what was measured, and what was corrected. That makes handoff, QA review, and dispute resolution much easier.

Yes, the measured leakage, pressure setpoint, calibration, and ambient condition fields can be paired with digital instrument readings or uploaded test reports. You can also use it alongside commissioning logs, photo attachments, or corrective action tracking. If your workflow integrates with another system, keep the template as the source record for acceptance.
