Just installed the Nest thermostat. On testing heater mode, it is starts the air conditioner.
On cool mode as well, it starts the air conditioner, which is fine.
Please help.

You have it wired the way I would wire it.
Try doing a factory reset on the thermostat and set it up again from scratch making sure to select only the W/W1, Y/Y1, G/G1, and R wires.
Nest thermostats are designed to work without a common ("C") wire in most homes. During installation, a small number of customers may find that the Nest Thermostat does not receive sufficient power. The Nest Power Connector or a C wire may be necessary. See g.co/nest/cwire for details.

I just had the same issue, but I also have a blue wire which is in the "
B" connection in my original thermostat. We tried it as the C wire and as the B wire with a factory reset each time we tried again. Never worked, so we put the old thermostat back to have a bit of heat for the night as we could only get it to blow cold air. Any additional suggestions? Maybe it isn't compatible? Here is the original wiring.

Start your own thread and don't hijack someone else's as it will get missed. You are lucky I saw this.

I'm so sorry. I didn't realize asking a follow up question would be considered "hijacking" another question. I was just trying to figure out if I could et an answer to a similar question.

Factory reset and selecting the wire configs you mentioned worked, probably I selected an incorrect wire setting.
Thanks a lot for your help!
