this meens it is really cold outside, turn the recirculation of air mode on so it blows warm air back into your face that is already in the cabin of the car. This will cause your windows to fog up faster though.

Check your coolant level, when you are parked your rpms are lower and if you are a bit low on coolant this might reduce your heat. Mine is currently doing the same thing. A thermostat malfunction can do the same, but that would effect the temp gauge reading too.

Have you had your water pump replaced?
Coolant flushed?
Clogged heater core?

+1 for checking coolant level. Turn on car and let coolant get warm (not HOT!) then turn on heat to high. Open radiator cap and I bet your coolant is low. Please don't do this while engine is hot or right after you've raced that civic in a school zone.
