I was Dispatched to perform a Post-Install Walk-Through. The Customer’s have concerns about Air Balancing and Airflow. The Customer’s also have issues with the lack of communication between them, the Installers and Kevin. They are not angry, just a little frustrated. I promised to discuss their issues with Russ. I addressed Airflow and Air Balance. I walked through the Operation of modern equipment and a brief tutorial on the Thermostat. The Customer was able to correctly work his way through setting up and programming the Thermostat. It is possible we could have to discuss adding some Dampers if the Balancing does not achieve the desired outcome.
