I am writing to formally log a complaint regarding the customer service experience I just had over the phone, and to get a definitive answer on my outstanding issue. I called to request a simple, clear update on when the rectification job for SO86031 will be completed. Unfortunately, the representative's tone was entirely unhelpful and unprofessional. Please look into this service standard issue, and more importantly, please provide me with the exact completion date for the rectification work immediately. I bought the aircon, I didn’t beg for it.

Very disappointed with MHI. Having issues with aircons bought from them. Nobody responded about it. My compressor issues.a sys2 which one of the unit is not working. They can’t repairs and most services recommended to change and buy new. That’s no good “AT All” ! Why have to change because of one unit failure? What kind of compressor is it? Better not buy Mitsubishi Heavy Industries aircons!!! Not recommended.

Replacing my 20 yo National and despite advice from many service men I bought a MHI rather than ME. Within 1 yr warranty broke down 2 times changed 3 parts. The techs know exactly what is wrong and to change fan coils or main pcb. They told me fan coil rusty. How can something contact condensation will rust regardless you use more or not. Now after warranty spoiled again cannot power off by remote. They won't care is it first time or multiple times quote $80 checking or $150 for labour + $90+ for a small part if not pcb. Real headache as is not only money but the hassle to take leave and the anxiety to expect it to down again. Hope KM service will be better if the product is not good.

Bought a Mitsubishi Heavy Industries (MHI) aircon system from U Sin Air-conditioning in Oct 2025. Within months, one indoor unit completely failed – no power, no LED lights, no response to remote or manual ON button. Very disappointed with both product reliability and after-sales support. Despite the unit being under warranty and completely unusable, the earliest service appointment offered was 4 days later. Expected much better quality and customer support from MHI. Regret this purchase.

My very old MHI blower recently stopped working - impressed with its longevity (MHI products have been consistently amazing in my experience). Recalling the pleasant and effective repair service I received three years ago, I contacted this company again for help. I reached out via their website over the weekend, and their follow-up was prompt. Scheduling an appointment was easy, thanks to a staff member named Joyce. The handymen arrived on time for the service call. While I didn't get the names of the three staff members, they were jovial, positive, and professional. They conducted systematic and thorough checks on my system to troubleshoot and eventually discovered the problem was due to a trivial issue. I wish to highly compliment the team for their professionalism, efficiency, and honesty. I had a very bad experience with another company where all they wanted was for me to change expensive parts or even replace the entire system - neither ethical nor kind to the environment! I didn't take down the names of my three aircon saviors, but the bill number was SO84685, should the company wish to identify them. I can't speak for everyone, but anecdotally, my experience with KM has been consistently great! I now feel assured about replacing my air conditioner with another MHI unit in the future, knowing I can rely on this team for reliable service and repair work.
