Daikin Authorized Service Ignored My Expansion Tank Replacement Request

On January 28, 2026, I called Daikin customer service and created a service request for my D2CND024 model boiler. During the call, I clearly explained that the filling valve had already been replaced by an unauthorized service about 2–3 months earlier, but the pressure problem with the boiler was still continuing.

On the same day, Daikin’s authorized service provider, Edremit Kuzey İklimlendirme, came to my home to inspect the unit. On the service form, the following note was recorded: “Visited for filling valve malfunction, expansion tank burst, filling valve malfunction resolved, maintenance performed, 1,750 received in cash.”

However, during my initial phone call I had explicitly stated that the filling valve had already been replaced earlier, so recording the service visit as if it were for that malfunction does not reflect the truth.

During the service visit, I also clearly requested that the expansion tank be replaced. However, two months have passed and I have received no response or update regarding this request. After this time, the service only contacted me to offer annual maintenance, and again my request regarding the faulty expansion tank was ignored.

There is also a contradiction regarding the 1,750 charge that was taken. In a conversation on March 14, 2026, I was told that this amount was for annual maintenance. However, being offered another annual maintenance service only two months later raises serious questions about what this payment was actually for.

For these reasons, I am filing a complaint against Daikin’s authorized service provider Edremit Kuzey İklimlendirme due to what I believe is an inaccurate service record, failure to address my expansion tank malfunction, and inconsistent billing practices.

I request that the matter be properly investigated, that the service records be corrected, and that I receive a clear written explanation stating what service the 1,750 payment was charged for and what steps will be taken to resolve the expansion tank malfunction.
