Heater question?

[Symba_The_Lyon]

So when i turn on my heater and i turn the fan on all the way up it feel like barley nothing is blowing out? any ideas?

Hot posotion only or cold position as well. Depending on which ones are slow you may have one or both heat exchangers clogged with debris.

Well both settings have very slow moving air coming out when it is on high, And where would these heat exchangers be located at?
