Just had a lovely Carrier Infinity system (furnace and a/c) installed; it's GREAT.
THE PROBLEM: I am going through those filters every two and one half WEEKS !!! Granted, I smoke and have pets but is this "normal"? Those things are mega expensive. Just replaced one on the 11th; it's showing 20% use today (Oct 14).
Does this have something to do with "static pressure", or ... ? I surely can't be the only owner who smokes, has pets and dirty ductwork.
At $30-$35 each, this system is eating me alive.
Thanks in advance.
