Use of pleated filters in this system =3D freezing of coils
Use of fiberglass filters in this system =3D no freezing of coils

Do the filters slide into the unit itself or do they go in the return grill?
Air flow problems. Might be any of several things. Might also be low on freon.
Filters go in what I call the intake.
Ground level framed in box leading to inside unit in the attic. (It was a favorite hiding place when growing up. :-) )
