this past November, my heating and A/C system began to make a disturbing sound, as if metal parts in it were about to break. I called a few companies, and they diagnosed the problem stating that it would cost at least $ 600. I then called New Comfort Air and Home Services at (602) 475-0989. I spoke with Eric Johnson. He came out, inspected the problem AND fixed it within a few hours, costing me about $ 180, more than 60 percent less what New Comfort's competitors quoted. For future service or replacement of my heating and a/c system, I will WITH NO HESITATION, contact New Comfort Air and Home Services at (602) 475-0989. They were professional, clean, reasonably priced AND spoke in terms I, a non A/C and heating guy, could understand!!!
