Daikin Applied (McQuay) service, maintenance and repair
McQuay is a brand of US origin that is also known today as Daikin Applied, the brand for the Daikin group's large-capacity (applied) products. In Türkiye it is offered through Daikin Türkiye; in older facilities you may encounter McQuay units, and in newer ones Daikin Applied labeled units.
The McQuay unit groups we service are chillers (including the Magnitude series), fan coils and air handling units. These units are usually found in buildings with large cooling loads such as hospitals, business centers, shopping malls and industrial facilities.
In maintenance and repair we start with measurement and evaluate the alarm history and operating data together. When parts are needed, we offer equivalent or original part options and proceed with the customer's approval. We recommend an annual maintenance contract for facilities that run continuously.

McQuay is the brand used for the large-capacity (applied) products of the Daikin group; in the field you may encounter both labels. We provide independent service for units with either label.
Do you service older McQuay chillers?
Yes. On older units we first make a general condition assessment and report the repair and overhaul options together with their costs.
Do you provide service outside Ankara?
In Ankara, our daily crews respond the same day. We have no branch outside Ankara; in other provinces we send a scheduled crew from Ankara, and the work is handled on a project, annual maintenance contract or public tender basis.
