It is an almost constant battle to get the heat where you want or need it in your home. In the winter you want more heat indoors and in the summer you are wanting less heat. A heat pump is designed to move the heat in your home from one place to another, in this case inside or outside your house.
Installation of your new heat pump would involve setting up the two systems it takes to make it run. Basically it is set up where you want the heat transferred from and where you want it moved to.
