I just bought a smart thermostat, can the Y and G wire tie to the common wire in order for the A/C to turn on?

Or will that effect the unit eventually?


This electric furnace does not have terminals with G, W, Y, C, R, RC screws, its wires instead.

Thanks

No, it doesn't work that way, you will blow a low voltage fuse if you ground (hook to common), the green, (fan) and yellow (ac) wires. Also, from the pic the unit is not grounded and that is a big mistake.
It is time to hire a pro and have him look over your system and fix it right.
