    Honeywell EAC is 1" smaller than duct, is OK?

    Hi, am planning to buy an F300 EAC, 20x25". My duct is 21x26" - could that cause any problem?

    I'll have to get some kind of graduated connector made up I imagine...

    Thanks and hope this post doesn't break the DIY rule...

    Assuming the duct system in general is properly sized and in good shape it should not be an issue that warrants making a transition IMO.
