Counterflashing

-A tractor like machine that is fixed with a blade on the front. It is used to push dirt around for grading purposes.

-Moves and conditions air through the ductwork. A fan sucks in new and return air and re-circulates it.

-Compressor/Condenser: the exterior unit of the heat pump. A fan pulls air across a line of refrigerant, and this changes the temperature. This adds heat for the winter but is run in reverse in the summer to let out heat.

Advantage: Heat pump systems can change conditions rapidly and also control other climate factors such as humidity

Disadvantage: Heat pumps can be very noisy, and they are also very difficult to zone.
