Why different fan speed for Heat and Cool
Oct 11 2009 · If the furnace/electric heat strip has a heat rise range (as per the furnace specification plate) of 35-65 degrees then the blower should be set on a speed that allows for an approximate 50 degree temperature rise from the return air inlet to the furnace/air handler outlet

Combustion Blower Centrifugal Blower Chamber Furnace
Combustion Blower . Major types are centrifugal blower and positive-displacement blower. Centrifugal blowers look more like centrifugal pumps than fans. The impeller is typically gear-driven and rotates as fast as 2900 rpm. In multi-stage blowers air is accelerated as it passes through each impeller.

The rule of thumb (around the bay area) is either 350 400 or 450 cfm per ton. So if you had 2.5 tons multiply that by 350cfm and you shoud be at about 775 for some dehumidification and about 900 cfm for a comfortable cool. the faster the fan spins the more air you move but the less time the air spends on the cold evaporator coil surface.
