Upon arrival I talked with the homeowner about her new SmartAC system I would be installing today. We went over all the options and where I placed the sensors downstairs in the basement. We were out here yesterday adding new returns and supplies to the home and she can already feel the difference in the home which is awesome! I had her download the SmartAC app and showed her how to schedule appointment and ordering new filters when needed. If you have any questions or concerns please call us immediately! Have a great weekend!
