Question about Heating & Cooling
"Y" terminal at the stat feeds condensing unit outside, common from the condensing unit to common on the furnace transformer.
"G" terminal on the stat brings the fan on for air circulation. In cooling mode "Y" terminal also brings the fan on. If this furnace was not A/C ready check the VA capacity of the transformer. Should be about 40VA. Make sure there is a fan relay to bring the fan on in the cooling mode.
