Cold air returns in the floor are not typical.


Nor atypical, particularly in retrofitted older homes. Cold air returns at
floor level on a wall are also not atypical, even in newer homes (as that's
where the cold air is during heating season).



I can understand that. As my house has a heat pump I guess that being
several feet off the floor is a good compromise for the air return. All
the outputs are at the floor level. Just an easy way to put them I
guess.
