If a contractor with the same certifications as us offers you a lower price for air conditioning sanitization, we’ll match the quote. It’s written in the contract.
Most air duct sanitization providers perform a mechanical intervention and leave you a generic sheet. No pre-test video inspection, no microbiological sampling, no parameter comparison.
When the local health authority or an ISO auditor arrives, that sheet proves nothing. The HICLEAN protocol exists to provide objective evidence of what was there before, what we’ve done, and what’s to come.
All signed by the hygienist biologist. Suitable for local health authority audits, ISO 45001 verifications, insurance applications, public tenders, and legal proceedings.
Every HICLEAN intervention begins with a technical inspection. No operational phase begins without first seeing the system.
What we evaluate
Condition of the AHUs, accessibility of the ducts, presence of inspection doors, type of terminals, system layout, general condition of the components.
What is it for?
Define the work plan, identify any obvious critical issues, estimate timeframes and operating procedures, and prepare a technical and financial proposal. We cannot provide estimates without a site visit.
Objective: determine the hygienic state of the air conditioning system with objective evidence.
ACTIVITY
OUTPUT
Condition of the AHUs, accessibility of the ducts, presence of inspection doors, type of terminals, system layout, general condition of the components.
This step allows the facility manager to quantify the level of contamination before authorizing the intervention. In the event of a future dispute, it provides proof that the preliminary inspection has been completed.
Objective: physical removal of contaminants accumulated in air ducts and air handling units.
ACTIVITY
Mechanical remediation always precedes chemical sanitation. Applying disinfectants to unremoved organic deposits is a methodological error that undermines the effectiveness of the intervention.
Objective: document the effectiveness of the intervention with comparable parameters.
ACTIVITY
OUTPUT
Condition of the AHUs, accessibility of the ducts, presence of inspection doors, type of terminals, system layout, general condition of the components.
This file is the documentary evidence needed for ASL audits, ISO 45001 audits, insurance requests, occupational disease proceedings, or public tenders requiring regulatory compliance.
To complete the remediation, we sanitize the entire environment—not just the pipes—with gaseous ozone produced by generators designed and built by us.
Ozone penetrates biofilm where traditional chemicals cannot reach, leaves no residue, and has documented effectiveness against bacteria, viruses, spores, and mold.
Treatment is ordered after a technical assessment. It is not automatic: it is performed when sampling results or environmental conditions require it. Concentration and contact times are calculated based on the specific volume.
The HICLEAN protocol does not end with the delivery of the technical file. For the entire duration of the contract and for 24 months following its termination:
ASL inspection or audit: the biologist shows up, brings the documentation and manages the technical comparison with the inspector
