Upon my arrival in Flatonia and I spoke with the customer about the concerns he was having with HVAC system. I checked the damper control and found that it was operational but the main zoning board was sending constant signal on both power to open and power to close terminals. This was causing the damper control to malfunction and stay closed. I spoke with the customer about his different options for repair and he chose to go with HZ2A. Will be ordering the parts Monday and getting with the office about scheduling the return. Currently left the faulted damper in the open position. The home is still cooling at this time. Customer also chose to sign up for our maintenance program.
