Inadequate Daikin Heat Pump Service Support In Istanbul, Turkey

Dear Daikin Team, Approximately 1.5 years ago, I purchased your Daikin EBVH16S23D6V Integrated Indoor Unit with Boiler (230-liter Stainless Steel Boiler) heat pump. At the time of installation, due to the unavailability of an authorized service provider in Istanbul, the installation was carried out by your service team from Tekirdağ. Recently, I have encountered a continuous increase in the system’s water pressure. Upon noticing this, I requested technical support, and the service team from Tekirdağ attended the issue. Despite explaining that the pressure increase began after the boiler was put into use, and suggesting a possible problem with the boiler, the team concluded that the issue might be due to the valves in the water installation, asserting that no mixing could occur within the underfloor heating system. Annual maintenance was carried out, and no fault was detected or reported. Following this, I engaged independent plumbers twice, and after valve replacements and thorough checks, it was confirmed that the valves were not the source of the issue. Moreover, an independent service expert indicated that the problem likely stems from a leak in the boiler’s heat exchanger coil. After further discussions with your Tekirdağ service team and a valve isolation test, they too acknowledged the possibility of a coil leak, promising a follow-up — however, no further action was taken. I am highly disappointed by the insufficient technical expertise demonstrated and the lack of follow-up communication, which does not align with Daikin’s reputation for excellence. Additionally, it is concerning that a high-end product has developed a significant fault within such a short period. In light of the above, • I formally lodge a complaint regarding the service I have received. • I kindly request immediate support from an authorized service team in Istanbul, capable of accurately diagnosing and repairing the fault. • Should such a service not be available, I request the return of the product and a full refund, as I intend to invest in a brand with a more robust after-sales service network. I look forward to your urgent response and resolution of this matter.
