Hi,
I bought the mitsubishi system 4 which consist of 3 x 10000 btu and 1 x 26000 btu for living room at 3799. Upgrade of insulation and copper piping at $230. and free 5 years extended warranty at the NEA road show in Dec. they got no stock for system 4 at the moment but they came to install the piping and trunking....during installation think they drill some hole nw my aircon power point trip when i on it at the MCCB. Installer will come rectify the problem when the stock comes. Overall, very pleased with the installation except the power trip. Hopefully, they can find the root cause. The person who served me is Peter from GV Marina. By the way, take note that for living room there are 2 model, 1 x 22000 btu and 1 x 26000 btu.
