Need to replace zone damper motor in office closet ceiling on lower level due sticking/not opening and causing cooling issues. Removed 14x6 return grill to gain access to zone damper motor to see how much room is around the motor and will need to open access hole to a larger hole and install new grill using a 14x14 or 14x8. Once damper is replaced then operation of zone dampers and cooling operation can be tested to confirm correct operation and refrigerant levels. Club member needs dispatch to call club member and set up an time for repair on exposed wires outside an for comfort advisor to come bye to discuss newer unit on 3rd level. I explained to club member one unit is over charged and the other unit was over charged making the units run inefficient. Club member is aware of both air Handler needs blower wheels cleaning along with evaporator coil cleaning.
