Technical references should shape the work
Every reference must be considered against the actual system, building condition, local requirements and approved scope. No standard replaces a technical survey or a project specific method statement.
References used to inform applicable work.
NADCA ACR 2025
A performance and procedure standard for the assessment, cleaning and restoration of HVAC systems.
It informs suitable HVAC inspection, source removal, containment and cleanliness verification practices. Reference to the standard does not by itself claim NADCA membership or certification.
View reference →ASHRAE and ACCA Standard 180, 2018
A standard practice for inspection and maintenance of commercial building HVAC systems.
It helps facility teams structure HVAC inspection and maintenance. It is not a dedicated air duct cleaning procedure and does not replace a project method statement.
View reference →NFPA 96, 2024
A fire safety standard for ventilation control and fire protection in commercial cooking operations.
It is relevant to kitchen exhaust inspection and cleaning decisions. Local law, the authority having jurisdiction and the facility fire strategy determine what applies at a specific property.
View reference →Facility EHS and permit controls
The safety, access, isolation and permit rules approved by the facility.
The project plan must address work at height, energy isolation, chemical handling, waste control and any other site requirements that apply to the approved scope.

The exact pack changes by service and contract, but the principle stays constant: the facility should receive practical evidence of scope completion and a clear record of observed constraints.
Recommended core documents
- Joint completion or job closure record
- Matched photo or video evidence
- Cleaning certificate
- Hood/service sticker where applicable
- Observed condition and recommended next action
