Hello,
What is a "heat pump"?

See:
http://en.wikipedia.org/wiki/Heat_pump

What is in the box? I know
the fan is in it, however i think there is something else in
there - scary- huh?
Here on this site

It's the *condensing unit*. It sits outside, while the other half,
called the *air handler unit*, sits indoors (usually). A true heat
pump can work in only one direction, or in either direction,
depending on design. But by convention, most reversible systems are
called "heat pumps" and one-way systems are called "air
conditioners" or "heat pumps", depending on which way they pump the
heat. A "heat pump" pumps the heat indoors, and an "air conditioner"
pumps the heat outdoors.

Split systems are more generally referred to as "heat pumps", while
window and wall units are more generally referred to as "air
conditioners".
But that's not politically correct either, since technically, air
conditioners are heat pumps. ;-
