House had high voltage electrical issues which damaged the transformer for the zone board and the zone board. The homeowner had me replace the transformer but didn’t have the funds at the time to replace the zone board. I unhooked the zoning per customers request so the mainfloor thermostat controls the hvac system. The system needs updated flood protection, a new zone board and a bypass damper for it to run properly. I emailed estimates for repairs. The heating and cooling was operating via the mainfloor thermostat at the end of service call. NO WARRANTY on this call or repairs done here today. Customer declined full repair options today. I got them temporarily running.
