Infinity Thermostat

Carrier Residential needed help to define, design, and test a new homeowner mobile app and wall control for the top tier brand 'Infinity'. We carried out competitor research, customer testing, and created a robust repository of learnings about customer types, and a roadmap to launching and iterating the Infinity System.

The Challenge

To better understand the smart home space, we interviewed families to better understand expectations for how a smart home climate controller could work. Based off user feedback from several rounds of testing prototypes, we established an app and wall controller that was extended into a design system and UI/UX documentation.

We iterated on the designs and built focused prototypes that honed in on interactions and feedback to minimize the need to onboard users. The goal was to make the app as intuative and informative as possible to give users peace of mind. 

As we progressed with user testing 2 different types of users emerged. Some users liked to set a range and never use the app again, while others liked to periodically check the temperature and adjust daily/weekly. We designed modes/experiences that would address both types.

We tested different user flows on homeowners across the country and in different climates to better understand edge cases. This approach uncovered and prioritize features which ultimately led to us building out a feature roadmap that would, overtime create a best in class smart home experience.

The design team created a component library for both the wall controller and mobile app. Along with this we documented user research, interacton flows, user types and other information to help inform and grow the smart thermostat team within Carrier.
