Need help wiring

[Toomuchwork]

I recently got a 3rd generation and ran into some trouble with the wiring.  When testing my heat it does blow from my vents but when testing the fan, its blow fine.  
when I uninstalled my old thermostat it only showed 2 red wired and 2 white wires.  Now this is in my home where  I have a gas furnace and and cooling system, forced air. 
the temperature been getting really could now and The house it not warming, I’m believing my wires are not connected properly from the beginning.

there was blue tape on a 1 white wire hiding the W and 1 covering the red wired R, maybe that meant something? The other 2 were in the Y&G. 
cant someone help me out and trying to figure this out.

White W in W1
