I think when you purchased your air-con, it is important to know who you are buying from. Especially those from Malaysia as you will never know if they will close up after you place your purchase. Think is better to get it from SG shops. Save yourself some trouble to get things done. I am currently looking for new air-con (system 3) and I have 2 quote from 2 brands Fujitsu $2699 (EJ electrical from amk) Mitsubishi Eletric Starmex $3800 (HDB forum) Material Used: - 1/2 inch Armaflex Insulation - G23 Copper Coil - 16mm Drainage Pipe with Armaflex Insulation 2 trip installation, 1st for install of piping, then you paint the whole house plus trunking, after renovation complete they will come back to install the FCU. This prevent dust and smell to get trap in the blower. (At no extra cost) Warranty: Installation Warranty 1 Year FCU Warranty 1 Year (By Agent) Compressor Warranty 5 Years (By Agent) Both provided the same specs for material but the price differ alot. Although knowing Mitsubishi as the premium brand for air-con, but I can save up the money, as both are same system air-con, isnt it. Anyone has any feedbacks on Fujitsu air-con? Please share with me. Thanks!
