Hardware and mobile application interface design system for Wi-Fi connected thermostats from the world’s leading HVAC company
Beginning in 2015, the UX team at GS&F designed the mobile application and hardware UI for Carrier's budget smart thermostat models, the Côr 5C and 7C. Over the course of two years, we continuously designed out additional features, ran experiments to validate new feature concepts, and worked with Carrier's offshore development team to execute those designs.
Through the course of working on the Côr 5C and 7C thermostats, we discovered that the user experience and aesthetic for the full Côr line of products was badly disjointed. Not only did the user interface completely differ between models, but in almost all cases the mobile application and hardware interfaces shared few similarities as well. For a brand struggling to assert itself in a market created by Nest, the lack of consistency and poor user experience (in addition to other factors) were hindering Carrier's ability to compete.
