Your Nest Thermostat could soon save your heating from breaking down

If you have a Google Nest Thermostat, you'll know that the smart heating device will send you alerts when there are immediate problems with your HVAC system (Heating Ventilation and Air Conditioning). Now, Google is trialling a new feature that will tell you about any potential problems before they arise, potentially saving your heating from breaking down entirely. Using artificial intelligence, Nest Thermostats, including the Nest Thermostat E and the Nest Learning Thermostat, will learn "how to identify unusual patterns related to your HVAC system," factoring in historical data and the current weather conditions – patterns that you probably wouldn't be aware of until your furnace or AC stops working. In a blog post, Google explains: "Sometimes, your HVAC system shows warning signs that it's having issues. For example, if it takes longer than normal to cool your home, there might be a problem with your cooling system (AC). If your Nest thermostat detects these unusual or unexpected patterns, we may send you an email alert."
