My ac system keeps freezing up on the condensate unit on top. I only had this problem a couple of times last year but this years its every day nothing has changed. I am wondering if i need a bigger blower.
I have a 2 story house with the unit down stairs. I keep the doors closed so the cold air stays upstairs, there is only one register down stairs that stays closed. It stays plenty cold down there.
I do not have any return duct that comes from upstairs. just sucks from downstairs.
