Aldağ service, maintenance and repair

Aldağ is a manufacturer of air conditioning and ventilation equipment of Turkish origin. Aldağ equipment is often found in public buildings, hospitals, schools, shopping areas and industrial facilities.

The Aldağ equipment groups we service are air handling units, fan coil units and chillers. Since these units are often part of the same central system, we plan maintenance within the system as a whole.

In case of a fault, we first confirm the problem by measurement and observation, then submit the repair proposal for the customer's approval. When a part is needed, the equivalent or original part option is determined with the customer's approval. For public institutions and businesses with many units, we offer annual maintenance contracts and tender-based service.
