I contacted Air Flex to request assistance with relocating my air conditioning unit that was loose from the wall where it was installed. On speaking with Lindon, we also discussed the efficiency of my furnace. When we were done, it was concluded that I could replace my unit with a newer, and more efficient unit, and also receive incentives for the replacement. He and I were back and forth discussing this issue throughout the day, and way into the evening hours. The next day, I confirmed with Lindon that I wished for the replacement furnace unit, and he scheduled a visit within the next two days. I found Lindon, Camille, and the technicians (Henry and Timur), that replaced my unit, to be very efficient, and highly professional. All my questions and concerns were responded to in a knowledgeable manner. No mess was left behind by the technicians, and they completed the replacement within 4 hours, instead of the previously advised 6 hours. I intend to contact Air Flex in the near future, to replace my air conditioning unit(which was the reason for my initial call to them), and would easily give them a 10 out of 10 for service. I highly recommend this company!
