Its because air is forced into the furnace to increase temperature. Steve.
We are having a new oil forced air furance installed tomorrow. With labor and removal of the old furnace, it is costing us $2460.00. We did get quotes as high as $3000.00.

Approximate external static pressure in the supply air plenum of a forced warm air furnace is 0.2" w.c to 0.5 "w.c
You must have a heat pump with electric auxilliary heat.
The primary function of a forced air furnace is to heat air, which is then distributed throughout the home via ducts to provide warmth to the living spaces. This type of furnace uses a blower to push the heated air through the ductwork system, ensuring consistent and efficient heating.
The cost is determined by the size of the grille. $.40/square inch

This means there is a blower attached to the system that forces the heat into the home.
