Google Nest Thermostat (2020) Review: 8.2/10 - Smart temperature control made accessible
Overview
The Google Nest Thermostat (2020) brings intelligent climate control to the mass market at a more accessible $129 price point compared to the flagship Nest Learning Thermostat. This model features a sleek mirror-finish display with Google Assistant built in, allowing voice control of temperature and smart home devices. It works with the Google Home app for scheduling, remote control, and energy usage insights.
Design & Build
The 2020 Nest Thermostat adopts a simpler, more compact design than its Learning Thermostat sibling, with a glossy polycarbonate face available in four colors. The 2.4-inch touch-sensitive display shows temperature, weather, and time, and it illuminates when you approach thanks to the built-in proximity sensor. The device is powered either by a standard C-wire or an included USB-C wall adapter, making it compatible with a wider range of homes. Build quality feels solid for the price, though the materials are less premium than the metal-ringed Learning Thermostat.
Performance
Temperature control is accurate and responsive, with the thermostat learning your schedule over the first week and adjusting automatically. The built-in Nest Temperature Sensors can be paired with additional room sensors to eliminate hot and cold spots. Energy History reports show how much heating and cooling your home uses and offer tips to save. The device also supports HVAC monitoring that alerts you if something is wrong with your system. Integration with Google Assistant and Amazon Alexa is seamless, and the Matter-ready firmware ensures future smart home compatibility.
Features
Google Assistant is built directly into the thermostat, enabling hands-free temperature adjustments, weather queries, and smart home device control. The Google Home app provides scheduling, presence sensing via phone location, and HVAC air filter reminders. The thermostat supports multi-zone systems and can work as part of a broader Nest smart home ecosystem with Nest Cameras and Nest Doorbells. Energy savings of up to 12% on heating and 15% on cooling are typical according to Nest’s internal studies.
