For air-con, I believed only in the established brand that is currently available. Not saying that Toshiba is not a good brand but whenever we spoke about air-con, I always recommend Mitsubishi Starmax. The brand is not only reliable, but it provide an excellent cooling environment to take a nap or during humid weather. Furthermore, it is very quiet and most importantly, it does not consume too much electricity as my parents York Brand. I am recommending them to change too. I am using it for the past 6 months and everytime is working just the right way that I want it. Will like to recommend to anyone who are deciding on their air-con brand. Special mention to the shop that I purchased, as they handled my installation of air-con very well, including providing me with details of the material used, workmanship (after 6 months, working perfectly well. Will continue to monitor) and most importantly, Price. So if you want to make an enquiry for a Mitsubishi air-con, can check out with EverJoin Electrical Trading, located at AMK ave 4. Can't remember their exact door number, but it is just beside the SgPools. Perhaps you can try your luck getting a Toto or 4D while you conduct your scouting at the shop.
