Please help. I'm really NOT satisfied and I need advice.
........... = 1,200 CFM total
A few 12x12" return air grilles ( up to ~200 CFM each) should be located in the bedrooms.
So with ~800 CFM remaining, put an 18" x 18" return air grille with filter and run to the air handler with 16"
diameter flexible duct.
R.A. grille can easily be 20 feet from the air handler.
If the installed unit is not 3 ton, revise appropriately.
Re: Returns w/ & w/o Filters
I put returns in every bedroom but I don't use filter grills. 90% of our installs get media filters and the rest are a standard 1 inch filter and the returns are all filtered at the unit. Is it common to put filter grills in each bedroom in Florida? That would mean changing at least 4 filters every month in a 3 bedroom home.

I never put several small filter grills in because they would be a pain to change.
are more or less required
due to State Building Code.
So, if you have them, USE them.
