Technician was not experienced. After maintenance check was complete I asked the maintenance check list for my unit that showed all number and recordings and the tech told me it would be emailed with my invoice. That was a lie. I Told him that last summer we had problems and asked if he found anything wrong and he replied everything we good. Today my has 81°F with thermostat set on 66°F. I also called in yesterday and asked to speak with a Manager. I was told he was in the field but they would send him a massage and he would call me but that never happened.
