The new Nest thermostat isn't the only model that can alert you if something is amiss with your HVAC system. All Nest thermostats are now capable of identifying if something is wrong with your HVAC system. Google rolled out an update in the US and in some parts of Canada that allows the device to monitor your system.
It started as a side project for Nest software engineers two years ago, and the company started testing it out earlier this year. The team was able to develop the feature because of cloud computing advancements in recent years. During the test, it sent users who sign up for Nest Home Report alerts if the Nest thermostat finds some errors with their heating, ventilation, or AC.
If there are any problems, the system will send you an alert via email or through the Google Home app. It's possible to receive urgent alerts for issues that may need immediate attention. It can also send early warning alerts for the non-urgent ones.
The Nest thermostat will spot anomalies by keeping track of the estimated ambient and target temperature. It makes sure it's at the right temperature based on how long the AC or heating has been running.
