NADCA-style deep cleaning of AHUs, supply / return ducts and kitchen exhaust hoods — eliminating fire load and indoor air contaminants.
Kitchen exhaust ducts coated with grease are the #1 cause of commercial kitchen fires. HVAC ducts choked with dust, mould and microbial growth degrade indoor air quality and trigger occupant complaints in offices, hospitals and hotels.
Robotic camera survey of duct interiors and grease deposit mapping.
HEPA-filtered extraction units to contain dislodged contaminants.
Rotary brushes and air whips dislodge grease, dust and biofilm.
All debris captured at source — zero contamination of occupied space.
AHU coils foamed and rinsed; drain pans disinfected against mould.
Post-clean CCTV footage and NADCA-style cleanliness verification.
Grease deposits removed to bare metal — meeting NFPA 96 guidance.
Lower CO₂, VOCs and microbial counts at occupant level.
Clean coils and ducts cut HVAC power draw by 10–15%.
Documented evidence supports your fire and property insurance terms.
