No. This is a downflow system and the return is in the attic and the grille is on the ceiling.Originally posted by tinknocker service tech
return temps 66/68. are your returns low near the floor?
i have seen where low wall returns bringing back cold air affect the txv. cold air as a rule falls and hot air raises and it sounds like you are pulling back all supply.this will make the coil colder and not pull out as much humidity. if this is the case take a three sided box two feet high put in front of the return and see if pulling the air from a higher point makes any differance
