Goodman Gas furnace and ac unit all new,Im installing it myself,new duckwork,I made(looks good) The situation is the wiring to the ac and to the furnace,Do I just put red with red and so on the all the wiring to the thermostat? Easy?

Thank you

Yes,, but after you get the wiring done ,you might want to call in a experanced hvac teck to look over what you`ve done, it will cost a few bucks but since you installed yourself you won`t have a warranty on the equipment, so you don`t want a simple mistake to cause damage that could cost you extra bucks
