If energy is a concern, check out a variable speed blower unit, most mfgrs
have them.
These typically operate at a fraction of a constant speed blower, mine is
saving about $15.00 a month (operates 24/7 for comfort)
Also noteworthy, even a constant speed conventional system blower will
operate much cheaper than a high velocity system of similar size.
High velocity systems pack a much larger motor to overcome the static
pressure of the system.
I've worked with 2-1/2 ton High Vel systems that had 1 HP+ blower motors.
Compare this to the nominal 1/4 to 1/3 HP blower in a conventional furnace &
the savings is obvious.
The upgrade to a variable speed blower results in a huge savings & the
comfort is far superior, which is, after all, what we're aiming for...
goodluck
