My airconditioning vents has minimual air flow in the attic?

Question

I have 3 vents in my finished attic. The space is only about 400 sq feet. I have to place my hand up against the vent in order to feel a trickle of air. The room stays un godly hot. I had to buy a window unit to enjoy the space.

Answer 1

If the coil is free of ice,maybe the unit cannot supply the needed cfm's if the attic is an add on.The ducts could also be mis sized or not strategically attached and located on the trunk.Check for ice on the coil by running your blower by itself for a half hour or so and see if it starts blowing better when put back to cool.Good luck.

Answer 2

suggest to throttle  (cut back) on the  vents to the rooms lower then the attic to force more air up.Also check the air filter to insure it is not plugging off
