A customer in Mumbai recently shared a first-hand experience following the installation of two newly purchased Daikin air conditioners on X. The units were reportedly installed by Swastik Engineering, a service partner said to be associated with Daikin in the region. According to the customer, both ACs began leaking water almost immediately after installation. While technicians on site addressed the leakage, one of the units later displayed a UO error code, which according to the post, seemed to have happened after the technicians left.
Publicly available information on Daikin’s own technical documentation and user forums suggests that a UO error code commonly indicates a shortage or leakage of refrigerant within the system. For consumers, this typically translates to an interruption in cooling performance and a potential need for technical inspection.
Got 2 new #DaikinACs installed today via Swastik Engineering, said to be area reps in Mumbai. Both units leaked initially, which was fixed. But now one shows a UO error, which seems to mean refrigerant leak or shortage. Disappointed on day 1. @DaikinIndia @daikin_jp #Daikin

The incident occurred within hours of installation, raising questions about either the equipment’s condition at the time of delivery or possible lapses during the installation process. There is no official confirmation at this stage regarding the exact cause of the error, and it is unclear whether the issue stemmed from the product, installation, or any other factors.
Daikin, known globally for its Japanese engineering and long-standing reputation in the HVAC industry, is often regarded as a premium player in the Indian market. The brand has built its positioning on the back of consistent performance and durable build quality. That’s precisely why this situation has gained attention. When customers opt for a premium product, they expect a premium experience from start to finish.
The installation experience plays a pivotal role in shaping how customers perceive a brand. Even a technically sound unit can underperform if not installed correctly. While Swastik Engineering has not issued any comment, the sequence of events described by the customer suggests a gap somewhere in the product-to-performance journey. At this point, there is no indication of any intentional fault or negligence from any party involved.
Technical errors can occur across brands, models and categories. It is the response and resolution that ultimately determines whether customer trust is sustained. In this case, the expectation is that the issue will be addressed promptly by the service team or the manufacturer, restoring confidence in the process and product.
What makes this report noteworthy is not the presence of a fault, but the timing of it. When issues appear on day one, they leave an impression. Especially for consumers who have made a considered investment based on brand reputation, peer recommendation and perceived product reliability.
This situation is a reminder that every touchpoint matters. A positive resolution here will not only benefit the affected customer but also reinforce Daikin’s image as a brand that stands behind its products, even when unexpected situations arise.
Key takeaways
