Turkish manufacturers

Imported and international brands

Older installed units (service and spare parts)

Brand names and logos belong to their respective owners and are used only to indicate equipment compatibility. YOİ Mühendislik serves all brands as an independent service provider holding a TSE Service Competence Certificate (HYB No: 12850); this does not mean we are the authorised service agent of any manufacturer named.

Brands not on the list

We also service fan coils not on this list, from manufacturers that are no longer in business, or with an unreadable rating plate. The core parts of a fan coil (motor, valve, coil, drain pan, thermostat) are similar regardless of brand; we match parts by dimensions and technical values.

Frequently asked questions

Which fan coil brands do you service?

We service all brands, including Turkish manufacturers (Aldağ, Üntes, Form, Arçelik, Ventas, Teknogen, Genka and others), imported brands (Daikin, Carrier, Systemair, Mitsubishi Electric, Trane, York, Aermec, Galletti, Sabiana and others) and older installed units.

Can you put a building with several different brands under one contract?

Yes. We bring all the units in the building into a single inventory and manage them with one maintenance calendar and one contract.
