Ensuring healthy indoor air quality
Causes of microbial growth
Moisture in your building's ventilation is often a breeding ground for mould, fungus and Legionella bacteria.
- Unit structure compromise (e.g. roof leakage, door gasket failure)
- Internal/external moisture (condensation from AC coils, fresh air intake pulling in rain or snow)
- Condensation pans/drains failure
Acoustic insulation damage
Insulation surrounding your HVAC system is often damaged. This occurs because:
- Over time, insulation becomes dehydrated and lining integrity is compromised
- Mechanical repairs performed disturb existing insulation
- A broken belt hits the insulation, breaks the outer liner exposing raw fibers to the airstream
Dangers of insulation damage
We ensure insulation remains intact to avoid:
- Damaged insulation entering airstream through the fan unit, contaminating ventilation system
- Causing indoor air quality complaints such as acute irritation to the skin, eyes and respiratory tract
The solution: HVAC hygiene maintenance program clean diffuers
Keeping your diffusers clean will:
- Prevents occupants from worrying about air quality
- Facility’s aesthetic appearance is maintained
Filter Inspection
- We inspect your filters and filter rack, ensuring proper fit and preventing filter bypass from occurring.
- We are also pleased to change your filters.
- Making sure the unit is OFF, not drawing in any unfiltered air to the system, client-supplied filters will be changed on an as need basis.
