Frequently Asked Questions
Quick answers to the most common questions about HVAC hygiene, indoor air quality and compliance so you can maintain a safer, healthier environment for your staff and tenants.
Do you provide full HVAC hygiene audits?
Yes. HIFLOW delivers full HVAC hygiene and indoor air quality audits, including system condition assessments, photographic reporting, contamination checks and compliance verification under AS/NZS standards. All audits are completed by trained hygiene specialists.
What standards do you follow?

Can you service multiple sites across states?

Do you handle emergency contamination or IAQ issues?
We provide 24/7 response for urgent contamination events, air quality complaints, system failures or tenant health concerns. Our technicians assess the issue, contain risks, and take corrective action to restore safe system operation quickly.
How often should HVAC hygiene be serviced?
Service frequency depends on building use, system type and contamination risk. As a guide, most commercial assets require hygiene servicing annually, with higher-risk environments—such as healthcare, food handling, or high-density occupancy—requiring more frequent inspection. We can recommend the ideal schedule for your facility.
Do you provide photographic and compliance reporting?
Yes. Every hygiene service includes photographic before-and-after evidence, contamination grading, corrective recommendations, and compliance records suitable for audits, insurers, and building risk frameworks.
