Performed system estimate. 44k btu of ac needed for home. Recommending 2 stage or variable for three zone application. Crane will be necessary. 9”,10”,12” damper needed. 12” bypass. Celeste take a look at things on her end and make a decision. Zone board was broken, with her permission I bypassed the board and wired the 2nd floor thermostat into the furnace. Other two thermostats will remain blank and dampers will stay open. Coil looks to be busted so I let her know if water starts to drip, shut system off asap because the coil froze over. Only system for the home and pets in house.
