Thanks for asking. Sorry to hear you're having issues with cooling on your Nest Thermostat Gen 4. If your thermostat's screen is changing color, it’s trying to turn your system on. To determine if it's a system issue, if you can, reinstall your old thermostat and test the system. This will help differentiate between a maintenance problem or insufficient power supply to your thermostat. If your old thermostat works, your Nest thermostat likely has a wiring or power issue. If both thermostats have issues, your system may need maintenance. We’re if you have any questions or issues: https://support.google.com/googlenest/gethelp
