I had my furnace installed in winter now my ac compressor won't turn on need to no what color wires go were for thermostat

Look at your control board, either they plug in or are hard wired, either way each wire is/should be labeled on board,, the norm is hot wire+red goes to rh/r/c on tstat
The green goes to G on stat, the white goes to W on stat,, yellow to yellow,, you have 2 wire going from furnace to condenser unit yellow from stat, blue or any color to the blue common wire or post

R to r
W to w
G to g
Y to y

I hope this helps sometimes the tstat wires don`t have these colors,, just make sure the match on both ends

The diagram should be stuck to the inside of furnace door
