Hello:

I just had a new AC and Heating unit installed. It seems that the flow
of air is less than with the old Lennox.
The previous system was a 3 ton and this is supposed to be a 3.5 ton.
I increased by .5 because i wanted it
to be a bit stronger to reach some further rooms. However it seems
that the opposite has happened.

Can anyone tell me what ton my blower is based on this information?
And any suggestions. I have had the installed come out and all vents
are between 300-500 cfm. temperature drop is 22 degrees.

Thanks
