I recently decided to install an air conditioner in my study. Naturally, caring about the environment (but not enough to forego my comfort) I chose the most energy efficient model on the market (the only 6 star split system). Got a phone call yesterday – the importer is out of stock until mid-December. Apparently they so misread the demand for this unit that they have none to sell during the peak sales season!
