Got a nasty dump of snow these past couple days and the Daikin Heat Pump has worked flawlessly and kept the house warm. Very impressed so far with this system. Even more impressed today when I was finally able to be outside without being attacked by the wind and the snow to check the outside unit and to see a that it has a wall of ice on the intake side and yet somehow it still sucks the air and extracts the heat. Pretty amazing technology considering. It's -6.5C outside and its still pumping heat.
