As your trusted local HVAC experts in Tucson, AZ, City Heating and Cooling is here to help you understand what this change means—and how to upgrade without any hassle.
Why Is Google Ending Support for Older Nest Thermostats?
Technology evolves quickly, and so do smart home devices. Google is focusing on its newer models to provide improved performance, smarter automation, and better energy efficiency. As a result, the 1st and 2nd generation Nest Learning Thermostats will no longer receive:
Security updates
Software improvements
Compatibility with new features
Full customer support
Without these updates, your thermostat may not function as reliably—and could even become vulnerable to security risks.
How Do I Know Which Nest Thermostat I Have?
To check your thermostat’s model:
Open the Nest app or Google Home app.
Go to Settings > Technical Info.
Look for the model number (e.g., 1st Gen: Display-1.0, 2nd Gen: Display-2.0).
If your thermostat is from 2011–2014, it’s likely one of the affected models.
What Are My Upgrade Options?
Upgrading your thermostat not only restores full functionality—it can also boost your home's energy efficiency. Newer Nest models offer:
Smarter learning features
Improved energy-saving reports
Compatibility with the latest HVAC systems
Seamless integration with Google Assistant and Alexa
We recommend the Nest Learning Thermostat (3rd Gen) or the Nest Thermostat (2020 model) for most homes.
