Ventilation Cleaning
Breathe cleaner air every day.
Ventilation cleaning and maintenance: a matter of well-being and safety
To ensure your employees and customers breathe healthy air every day, your ventilation systems must be kept in perfect condition. Regular cleaning removes dust, allergens, bacteria and residual grease that would otherwise build up in air ducts and equipment. By servicing your installations, DOSIM improves indoor air quality, reduces fire and health risks, and supports the comfort and well-being of your teams and customers, while ensuring the performance of your equipment.

We provide a complete cleaning service for your ventilation and air-conditioning systems to ensure air quality, equipment performance and compliance with hygiene requirements.
- Disinfection and dust removal of ventilation and air-conditioning ducts (HVAC, mechanical ventilation systems, air handling units)
- Degreasing of professional kitchen hoods and extraction networks (restaurants, canteens, hospitals)
- Maintenance of air vents, grilles, diffusers and textile ducts
- Cleaning of air handling units (AHUs) and their components: filters, coils, fans
Indoor air hygiene and quality
We help create healthier environments by addressing sources of microbiological air contamination.
- Bacterial and fungal disinfection to prevent health risks (legionella, mould, allergens)
- Implementation of sanitary monitoring plans to ensure indoor air quality
- Microbiological sampling and laboratory analysis (air and surfaces) by an accredited lab
Energy optimization and performance
We service your ventilation and air-conditioning systems to improve efficiency, extend their lifespan and reduce energy consumption.
- Dust removal from installations to reduce pressure losses and electricity use
- Inspection and replacement of clogged filters
- Recommendations to enhance the energy efficiency of ventilation and air-conditioning systems
Regulatory inspections and compliance
We support you in meeting regulatory requirements for your ventilation systems through rigorous, fully documented inspections.
- Visual and video inspections of air-duct networks
- Detailed service reports with photos and recommendations
- Compliance with hygiene, fire safety and occupational health standards
- Support during regulatory audits (DDPP, health inspections, safety commissions)
Sector-specific services
Because every environment comes with its own constraints, we tailor our interventions to your sector’s requirements.
- Commercial and institutional catering: cleaning and degreasing of hoods and ducts to prevent fire risks and comply with food hygiene standards.
- Healthcare and pharmaceutical sectors: cleaning in sensitive environments with reinforced procedures (sterile areas).
- Offices and commercial buildings: preventive maintenance to ensure occupant comfort.
- Industry: cleaning of complex duct networks subject to specific constraints (dust, chemical vapours).
Why have your ventilation systems cleaned?
Your ventilation systems play a key role in the comfort, safety and performance of your buildings. Yet without proper maintenance, dust, grease and particles build up in the ducts, leading to poorer air quality and reduced efficiency. Regular cleaning helps protect occupants’ health, optimize energy costs and ensure the long-term reliability of your installations.
