Maintenance of ventilation systems and installations

Maintenance of ventilation systems and installations is a legal requirement for commercial and industrial buildings, and at the same time key to air quality, energy consumption and the prevention of biological risks such as legionella.

Maintenance of ventilation systems and installations is a legal requirement for commercial and industrial buildings, and at the same time key to air quality, energy consumption and the prevention of biological risks such as legionella. BioClean by EZO Green provides a complete service for HVAC, ventilation ducts, heat recovery units and industrial air conditioning.

We work with all types of ventilation systems — from small office air-conditioning units to large industrial HVAC complexes in factories and hotels. We service equipment from manufacturers such as Daikin, Mitsubishi, LG, Carrier, Trane and others.

Regular ventilation maintenance cuts energy consumption by 10–20%, extends equipment life 2–3 times and prevents microbiological risks — including Legionella pneumophila, the cause of Legionnaires' disease, which is highly dangerous in industrial facilities with water systems.

Questions
we get most often

How often should a ventilation system be cleaned?
Legal minimum: annually for commercial premises, every six months for high-risk sites (hospitals, kitchens). For optimal efficiency — every 6 months.
Does production have to stop during servicing?
Not necessarily. We work in shifts, at weekends or during planned shutdowns. For smaller systems we can split the work into sections.
How do you prove the system is clean?
Visual inspection + video camera + sampling (mandatory for legionella). We issue a full report with before/after photos.
How much does energy consumption drop after servicing?
Depending on the condition — typically 10–20%. For neglected systems — up to 30%. The service pays for itself in 6–12 months.
