I return today to investigate damper issues on the zoned system. I found that the motors were sticking slightly on a loss of call. The dampers that are here are the power open spring clothes style. I am sending an estimate for the better quality power open power closed dampers. I sprayed WD-40 to help lubricate the which open and closes the damper. I verified that the refrigerant charges good. I am leaving an estimate for two dampers in case they are needed.
