Reason for getting Panasonic air con:

1. I have been using it for coming to 5 years with no problem in my previous house.
2. It comes with ionizer (nanoe-G).
3. My other choice that was considered was Mitsubishi Starmex, mainly due to the price being lower and the easy to clean design is favorable for home user.  
4. But I think all aircon blower should be regularly cleaned with appropriate chemicals to prevent growth of mould and fungus. 
5. Mitsubishi Starmex has no ionizer but Mitsubishi Heavy Industries have a "24-hr Tourmaline ionizer" which come to think I will rather get a more traditional type of ionizer like nanoe-G that can zap all the nasty stuff within the air of my room.
6. VERY COLD (From my experience at my previous home) and no water leakage from the blower for 5 straight years.
7. My aircon guy was with quality work and since I have used him before and my aircon has been running 5 years straight I chose him over other aircon contractor.
