Just to share, i have done my servicing with Aircon.guru, after discussing this with another user in a different forum. The website is user friendly and easy to navigate. all your booking info and request and schedule is in your account. Any changes you can live-chat with them or contact them. the Admin is pretty on the ball. But they do only standard stuff - regular cleaning, chemical wash and chemical overhaul. if you need repair, better to get someone else who can come and review. Altho Aircon.guru said they can help FOC, in terms of repair work they will just be the middle man to do the coordination.
