I trusted National Panasonic products so much that 80% of my home appliances are National Panasonic. Hence 3 out of 4 of my air conditioners are National Panasonic. My National air conditioners has never give me any technical problems and the only time I call in the technicains is after I renovated my house and need to shift the position of my air conditioner.
The latest one I buy is National Deluxe- ENVIO 12 Inverter.It has a BTU of 11 000 running on 3.23 KW which is very energy efficient . The indoor unit weights 9 kg and the outdoor unit weighs 31 kg. It comes with a built in E-ion purifying system and a patrol sensor . It also has an odour removing function . The panel is removable and washable too. It is super quiet while on. Like all air conditioners, it comes with a remote control and the airflow direction can be remotely or manually controlled to the left or to the right. It comes with automatic operation mode too .
Cons: None as Panasonic do lives up to its slogan - Ideas for Life.
