Air Changes Per Hour (ACH). Why They Matter.
Many commercial and institutional spaces are designed to meet specific Air Changes per Hour (ACH) requirements to help maintain proper ventilation and indoor air quality.
Examples include:
Classrooms
Medical and dental offices
Operating rooms
Laboratories and other specialized spaces
If your building isn't meeting its required ACH, it can impact occupant comfort, indoor air quality, and compliance with design or operational standards.
At Hydro-Air Technical Services Ltd., we can:
✔ Verify your current Air Changes Per Hour (ACH)
✔ Confirm your ventilation system is performing as intended
✔ Identify deficiencies
✔ Recommend and verify adjustments where necessary
Whether you're commissioning a new building, troubleshooting an existing system, or validating ventilation performance, our team can help ensure your building is operating as designed.
