Why Ecozen
Working with separate contractors for the chiller, boiler room and ventilation takes time. We manage the whole system as one team.
Our chiller stopped in the middle of summer. The Ecozen team arrived that evening and had the system running by morning.
Certified engineers
Staff trained to work with refrigerants and gas equipment.
Our own spare parts stock
The most-needed parts are kept in stock in Baku.
Transparent pricing
A written quote before work begins — no surprise costs later.
Measured diagnostics
Accurate results from gauges, thermometers and analysers, not guesswork.
