Look like you have central air with gas heat! Any nest would work up to your functions preference. 1 issue is only see 4 wires and nest requires a 5th wire to connect to C on sub mounting plate. You might have extra wires bundled up with exiting ones hopefully! If not you need to install extra wire or cancel the fan function to power nest all time but you need to do some rewiring at your furnace controls also. Good luck.

Hi there,
Thanks for posting in the Google Nest Community forum. I'm sorry for the delay. Could you please share with us the photo of the wires connected to your HVAC control board? Ensure that the labels of the wires are visible. It will help us to make sure the compatibility and wiring configuration of your system to the Nest Thermostats.
You can visit this support article for more information.
I appreciate your input, @HVAC.
Best,
Jenelyn
