:confused: I recently moved into a house & I can barely tell that any air is coming out. I have just paid to have all the ducts cleaned. Please help me figure this out.

Is the fan running? Is the filter clean? Is there dampers in the duct closed? These are the popular reasons air flow would not be working.

Yes I have replaced filter, checked damper, and the fan works.

OK then how about the fan, is is driving a belt? Perhaps the belt is broken. If not , is there any air coming out of any registers?

Also perhaps the fan is on a slow speed. Are you trying to heat or cool. Air handlers usually are set to slow speed for heat, and a higher speed for cool.

If the fan is running, and there is an obstructiuon, then you should hear the air being pushed or forced at the air handler. Or there could be a broken duct not allowing the air to reach the registers.

I hope these additional ideas are helpful. Beyond this, you may need to call in your furnace tech to check out the system.

Just a thought but some motors are reversible and it it happened to be a newly installed motor maybe it is turning the wrong way.
