The Tech just left, I will post up a few other reviews because the service and the workmanship have always been great. I have purchased THREE units from them and had service done 2 times. Well, this call was because I was unsure if the unit was working right. They came right out, spent over a hour making sure all the readings were correct and I even programmed the thermostat (Which made a huge difference).\n\nTHANKS SCOTTSDALE AIR!
