I was wondering, I noticed in the instructions for my thermostat that there is a way to connect seperate heat and coll transformers to the stat, but how would you connect seperate blower units? Would you parallel the G & W wires to each unit, but power off the one your not using at the time?

Well the idea would be to run the AC seperate from the furnace. Right now the old AC/furnace is blocked off and shut down and the new furnace is connected. In the summer I would like to reverse that and block off and shut down the new furnace and run the old AC instead.
If you are using one unit for heat and one for ac, Remove the jumper between rc and rh and wire as if it were two seperate transformers, which it is.
best of luck
That part I figured out, but what about the blower, which would be the W & G wires for the old furnace?
