So my thoughts are when the house hits 102 degrees, call Heath at Arctic Fox Heating and Air, (623) 533-5718, because he is seriously the best - and honest - and reasonable - keeps you updated, and does what he says he's going to do. We've had experiences with less than honest technicians from other company's and it's just not worth it. We just gave him keys to the house for three days, and we stayed in an air conditioned hotel! We completely trust Heath and his team, and have total respect for what he does.
