Hi Aron, Can I get a quote for inverter mitsubishi starmex system 1 (single unit) and inverter mitsubishi starmex system 3 for a 5 room HDB Bto? Can you also advise the capacity required for the single unit which is to be placed at the living room and dining area? Appreciate it if you could let me know the materials for installation, payment terms, warranty and any other costs involved. Thank you.
