Ventilation Cleaning
Preserving air quality means protecting everyone’s health within the facility.
Ensuring air quality in your sensitive environments
In a healthcare facility, ventilation is not just about thermal comfort: it plays a decisive role in infection control and in protecting vulnerable patients. Without proper maintenance, air-duct networks quickly become reservoirs of dust, bacteria and fine particles, potentially compromising care safety. At DOSIM, we provide the cleaning, disinfection and inspection of your ventilation systems in strict compliance with regulatory standards, ensuring safe, healthy indoor air at all times.
Our ventilation maintenance services
Cleaning and maintenance of ventilation networks
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 maintain a healthy environment by addressing sources of microbiological air contamination.
- Bacterial and fungal disinfection to prevent contamination 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
- Qualification of operating theatres in partnership with approved providers
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 for other industries
Because every environment comes with its own constraints, we tailor our interventions to the requirements of your sector.
- 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: preventive maintenance to ensure occupant comfort.
Why have your ventilation systems cleaned in healthcare environments?
In hospitals and clinics, air quality is a decisive factor for patient safety, staff comfort and the prevention of hospital-acquired infections. Yet without appropriate maintenance, ventilation networks accumulate dust, bacteria and fine particles, undermining infection-risk control and reducing system efficiency. Regular cleaning helps protect occupants’ health, ensure compliance with regulatory standards, and guarantee long-term equipment performance.
