Check blower wheel and indoor coil to make sure they are clean.

Customer: replied 11 months ago.
Where is the blower-wheel? In the attic?I assume the A-coil is in the heat pump unit? If so, how do I access it?
Expert:  airheatman replied 11 months ago.

Both will be in the air handler in attic. Also feel of the large copper pipe between units for signs of an iced indoor coil that may be restricting air flow.
