The zoning board was replaced and the Evolution system (3 tons, 4 zones) is now running with the zones. With just the smallest zone calling, the static pressure is 0.4. With other zones calling it drops to about 0.1. A few issues remain - there is some sweating where the plenum connects to the fan coil and the dampers are sweating also. These will be addressed in a day or so. The R-410 level needs to be checked again also. The duct analysis reported 8% damper leakage. The HVAC guy will also verify the duct design with the Enalysis hoods.
