Kns.. Kena complained by downstairs neighbour (7th floor). I stay at 12th floor (top floor) n he complained to HDB dat my condenser leaked water n he was irritated by the dripping sounds (no one install aircon frm 8th to 11th floors). Before CNY, he came up to my unit, smiling n politely asked me abt my aircon. I thus told him politely dat I'll ask my installer to check. Aft checking wif both the installer n Mitsubishi, both told me dat it's normal for the condenser to drip water once in awhile due to condensation. Few days later, the said neighbour came up again n asked me for update, which I relate which the installer n Mitsubishi told me. He then rebutted dat aircon can't be leaking n insisted dat I check again. I then replied dat I'll get Mitsubishi to come onsite to dbl check. I was then away at my mum's place during CNY. I came hm on the 4th day of CNY n on my aircon. Within 1 hrs, he knocked on my door n says :"U on aircon right?" He then asked me to get Mitsubishi to call him. It was CNY period so I delayed a few days. Who knws juz only 2 days aft dat, HDB called me n infd me dat they received a complain. Kns.. According to HDB act, regardless whether the aircon hv fault anot, as long as it causes nuisance to others (in my case normal water dripping frm NORMAL CONDENSATION), I still hv to rectify the issue. Kns! L L spent $150 to install a stainless steel tray beneath the aircon ledge, wif an extended piping to ensure the water drips beyond the perimeter of the neighbour aircon.
