Technical notes specific to Istanbul

Humidity in Istanbul stays high during summer months, which puts the focus on dehumidification load, drain line and pan cleaning in air conditioners. In buildings on the Bosphorus and coastline, salty air accelerates corrosion on outdoor unit coils, so coated coils and regular washing are important.

  • In plaza districts such as Maslak, Levent and Ataşehir, VRF and chiller systems are common, with fancoils and air handling units on office floors.
  • In the OSBs of İkitelli, Dudullu, Tuzla and Beylikdüzü, process cooling, compressor and cold room needs stand out.
  • In high-rise buildings, outdoor unit placement, long piping runs and oil return should be checked at the project stage.
  • Because of heavy traffic, planned maintenance appointments are grouped by district.

Frequently asked questions

Do you have an office or service team in Istanbul?

No. Our headquarters is in Etimesgut, Ankara. We send planned teams from Ankara to facilities in Istanbul and work on a contract, project and tender basis.

How soon can you come for an urgent breakdown in Istanbul?

We do not guarantee a time. Team dispatch time varies with distance and the current work plan. At contracted facilities we plan priorities, and in urgent cases we provide preliminary routing by phone.

Do you come to Istanbul for one-off maintenance?

We primarily plan annual contract and project-based work. For one-off jobs with sufficient scope (for example, a chiller group overhaul or collective VRF maintenance), we can prepare a quote as a project.

Is maintenance done differently in buildings near the coast?

Yes. Because of salty air, corrosion checks on outdoor units and condenser coils, surface cleaning and protective measures are added to the maintenance list.
