hi tim, need some advice"ation on my 5rm resale flat in sengkang, currently there is a system 3 which look quite new install in all 3 rooms and a old single system in the LR area, i have 2 options in mind. 1) keep the old system 3 in the room, just do servicing and change all the covers etc, need the quotation on this. Dismantle my 1horse power aircon from my room in amk to install in my LR in sengkang, need the quatation for the dismantle and installation, as well as whether its asking too much to use 1horse power aircon for my living room, the area estimated around 11m x 3.5m.. 2) install a new system 4 with inverter , prefer LG or open to suggestion if u have better advice. thanks alot!
