HVAC Commissioning Checklist: Free Template

What HVAC commissioning is

HVAC commissioning is the process of verifying that building mechanical systems are installed correctly, operate safely, and perform as designed. It brings together installation checks, electrical and control validation, testing, adjusting, and balancing (TAB), and operational checks so that equipment is ready for dependable startup and handover. This checklist covers HVAC equipment, pumping systems, piping infrastructure, and lighting controls.

Why it matters

Commissioning catches problems while the project and maintenance teams still have access to the systems. It verifies safety, compliance, and operational performance, and it documents that installation, controls, and balancing have been completed. The checklist also references TAB procedures per NEBB/AABC standards, which gives the balancing work a recognized framework.

What a good commissioning check covers

A complete commissioning check moves through installation, controls, TAB, and operations. Key areas include enclosure and general installation, piping and coils, fans and dampers, compressor and condenser, electrical and controls, and TAB. For pumping systems, it covers general installation, electrical and controls, VFD commissioning, TAB, and operations. For piping systems, it covers piping, valves, sensors and gauges, TAB, and fixtures and switches.

How to run the process

Use the checklist in sequence. Start with installation verification, then move to electrical and control checks, then TAB, and finish with operational checks. Record the result for each item and note any corrective action needed.

Frequently Asked Questions

Testing, adjusting, and balancing (TAB) is the process of measuring and adjusting air and water flows so the systems perform as designed. In this checklist, TAB items cover things like verifying that balancing dampers are installed and accessible, confirming duct leakage testing is completed and documented, and checking that dampers and linkages operate smoothly through their full range. TAB procedures are referenced to NEBB/AABC standards.

You verify fan and motor sheave alignment and belt tension, check that belt guards are installed and secured, confirm bearings and lubrication lines are properly lubricated, and ensure fan compartments are clean. For dampers, you confirm they close tightly, form a positive seal, and that linkages have minimal play and operate smoothly.

You check that all sensors are calibrated and verified against reference standards, that control sensors are calibrated against known reference values, and that OSAT, MAT, SAT, and RAT sensors are correctly positioned and secured, with the related outside air sensor properly shielded. You also confirm building automation system interlocks are connected and functionally verified, and that enthalpy controls and sensors are properly installed where applicable.

Commissioning verifies that installed equipment is safe, compliant, and performs as intended before handover. It covers installation verification, electrical and control validation, TAB, and operational checks so that issues like air leaks, misalignment, moisture in refrigerant lines, or uncalibrated sensors are found and corrected while the project team still has access to the systems.

The checklist breaks commissioning into sections: HVAC system commissioning (enclosure and general installation, piping and coils, fans and dampers, compressor and condenser, electrical and controls, TAB, and operations), pumping system commissioning (general installation, electrical and controls, VFD system, TAB, and operations), and piping system commissioning (piping, valves, sensors and gauges, TAB, and fixtures and switches).

For VFD commissioning, you work within the pumping system's VFD system section. You verify electrical connections, grounding, and control interfaces, and confirm the drive operates the pump as intended through the TAB and operations checks. Specific items include confirming sensors are calibrated, controls are functional, and the system performs correctly when adjusted.
