Help!
My heat pump is blowing cool air but isn't blowing very hard.
What could it be? Is it going to be expensive?:mad:

Check the filter.

Change your filter... turn unit off and turn fan on at t stat for about an hour. Than turn unit back on. If it continues call a tech out.

Please do as siberianair suggest. Turning the fan on with ac off will thaw the coil if it were froze do to a plugged filter. If you change the filter, thaw the coil, and it freezes up again, you will need to call in a pro to check system refrigerant charge and locate leak if charge is low. Please let us know what you find.
