About this app

Your heating and cooling system is at the center of what makes your home comfortable and also where you spend most on energy. The experts at Carrier® have developed a thermostat with intelligent controls designed to be the heart of a smarter home – a home where comfort and energy savings go hand-in-hand.

Control your home comfort wherever you roam with Wi-Fi® connectivity to your smartphone, tablet, or desktop. This app makes it easy to change temperatures, update your schedule, and maintain control of your home’s energy efficiency with the touch of a finger.

But as convenient as the Côr™ thermostat is to use, that’s only part of the story. The Côr thermostat helps take the guess work out of balancing your comfort and energy savings. Smart Features learn the characteristics of your home – and how you live in it – then use outdoor weather to intelligently adapt every day for greater efficiency while keeping you comfortable.

Monthly energy reports in your web portal help you understand your system’s performance, allowing you to modify settings to maximize savings. Or use our one-touch customized tips to save even more. Homeowners saved an average of 20% on their heating and cooling energy costs.*

I have used this app for about 5 years. It constantly losed my user and password. I give up. I'll just walk down the hall. I have used the same user name and password for the entire time, but it just forgets periodically. Also won't change from lanscape to portrait, so you can't read the instructions to reser, easily. Not worth the trouble.

Worst app ever. Almost impossible to use. Crashes frequently. Arbitrarily changes entered values. Logs you off. Makes you log in again. Impossible to use cached login credentials because iris sensors displayed at a 90 degree angle to your head. Can't rotate phone. Altogether, the most buggy, worthless app I have ever experienced. Worth buying a different HVAC system just to be able to control your comfort.

We have used this for 5 years and feel it could improve, but hasn't changed. You are forced to view the app in landscape mode. Sometimes the thermostat doesn't respond to one user, but I'd more responsive to another. We feel that you should also be able to change your password within the app. It is clunky and unintuitive. This app could use an update.
