Hi Aron, emailed Ah Boon but no reply still. Please provide a quotation for me. I have 2 aircon ledge so I would be able to accommodate 3 compressors. Need the 1 for 3 rooms (12 + 9 + 9), 1 for living and dining (18 + 12), and 1 for master-bedroom and study (18 +9). Would like the biggest compressors for all (is this necessary?, was informed that it would be better). Would like a quote for Mitsubishi, Daikin or Panasonic all inverter AIRCON, and to include installation plus materials used.
