Project description
Our two-story home currently runs on a single-zone forced-air system, and the temperature difference between the upstairs bedrooms and the main-floor living area has become impossible to manage with one thermostat. We need an experienced contractor to convert the existing ductwork into a three-zone system: main floor, upstairs bedrooms, and a finished basement office. The project starts with a full assessment of the existing trunk and branch ductwork to confirm static pressure and duct sizing can support zoning without starving any single zone of airflow. From there we need motorized dampers installed at the branch takeoffs feeding each zone, wired back to a central zone control panel mounted near the furnace and air handler. The control panel should interface with the existing furnace and AC condenser through the correct low-voltage terminals so staging and blower speed respond correctly when only one zone calls for conditioning. Three programmable thermostats need to be mounted, one per zone, and networked to the panel, with a bypass damper or dump zone configured to protect the equipment when only the smallest zone is active. Once everything is wired, we need a full airflow balancing test with an anemometer at each register to confirm CFM targets are met in every zone under different call combinations, plus documentation of any duct modifications made along the way. We are flexible on brand of equipment but want components that are compatible with each other and with our current furnace. Please include your approach to damper placement, expected number of visits, and how you handle re-balancing if the initial test shows uneven airflow.
