Maintenance of ventilation systems and installations

Maintenance of ventilation systems and installations is a legal requirement for commercial and industrial buildings, and also key to air quality, energy consumption and the prevention of biological risks.

Maintenance of ventilation systems and installations
in North Macedonia

Maintenance of ventilation systems and installations is a legal requirement for commercial and industrial buildings, and also key to air quality, energy consumption and the prevention of biological risks such as Legionella. EZO TEH offers a complete service for HVAC systems, ventilation ducts, heat recovery units and industrial air conditioning.

We work with all types of ventilation systems — from small office air conditioners 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.

A complete approach
for your facility

The complete package — biological products, a team certified to ISO 9001, 14001, 27001, 45001, 50001 and ADR, full documentation.

Ventilation duct cleaning

Mechanical and biological duct cleaning — removing dust, grease and biofilm. For all types of ducts (metal, flexible, fixed).

Heat recovery unit servicing

Cleaning and maintenance of heat recovery units — critical to the efficiency of HVAC systems. Regular servicing extends equipment life.

Industrial HVAC systems

Cleaning of large industrial ventilation complexes — factories, halls, warehouses. Planned overhauls without stopping production.

Questions
we are asked most often

How often should a ventilation system be cleaned?
Legal minimum: annually for commercial premises, every six months for high-risk premises (hospitals, kitchens). For optimum efficiency — every 6 months.
Does production stop during the service?
It doesn't have to. 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 condition — typically 10–20%. For neglected systems — up to 30%. The service pays for itself in 6–12 months.
