David did great work for years on my parents AC and Heating system. He was the best. He replaced the coil in the attic and the pan leaked, he replaced. His helper (per David) must have tighten the pan down wrong so it leaked again. David said he would fix it. It is now five months later, David made and cancelled five appointment, then would not return cell phone calls or text messages. I thought something had happened to him. I offered to pay him to fix the pan and he still does not return calls. The bad thing is this involves my middle 80 year old parents that do not understand why David has done what he has done and neither do I.
