different speed blower motors

I have 2 67s, one 3/4 ton & one 1/2 ton. The high blower setting on the 1/2 ton is much higher than the one on the 3/4 ton. Is that what deluxe air heater means?
Thanks in advance for the info.

No, they are both non-A/C.

Re: different speed blower motors

I always prefer to run the a/c blower, as it moves more air. Maybe someone has swapped one into yours.

Re: different speed blower motors

probably one has more resistance in the power, or more resistance in the ground, or one has a 44 year old blower and the other has a newer one...
Therre should be no reason as far as design though.
