Question about Fujitsu Heating & Cooling
When there is enough moisture in the air and the heater is running the moisture will freeze on the outside coils. When the unit senses this it reverses to the cooling mode which sends warm freon to the outside to melt the ice and then it will switch back to the heat mode. If this is the way yours is operating it is normal. It will help to shield it from rain and snow.

Actually, as the ambient increases the outside unit becomes more inefficient. Remember, air conditioners are merely heat pumps, they pump heat from inside to the outside adding in their own heat generation while they do so. The hotter the outside temps are the less efficiently can the fans cool the condensor coil. If the condensor isn't as cool as it can be, the indoor unit will be able to evaporate to a smaller extent, effectively dropping your cooling capacity. Reverse cycle is by far the most energy efficient system. If you calculate electricity input to heat production, you get 300% apparent efficiency. The reason is that they are heat pumps - they move heat from one place to another, rather than generate heat by burning fuel. But as the outside temps fall the unit can start to ice over which them forces the unit to shut down. If you live in an area where the outside temps drop below freezing or get down to 3-5� then a reverse cycle might not be the best. www.fujitsugeneral.com/PDF_06/halcyon06_brochure.pdf
