Cant use this app
You signed me out which I did not want you to do and you won’t let me sign back in with your continued excuses.
You’ve said I’ve timed out 5 times. Every night I have to go to my thermostat instead of convent doing it in bed.

Always. Forgets.
App would be fine if it didn’t ALWAYS forget the “devices” on our system. Basically every time I want to adjust our temperature, I open the app and I see my name, my address, but no HVAC units. I add them, not so hard, then adjust the temp. Then next time? Gone, I have to add them again. Go down to my HVAC unit, dig out the QR code, scan and enter. What’s the point of an app if I have to go visit my HVaC unit every time?
Sadly I’m going to say avoid Carrier until they fix this. It has been going on since they forced everyone on to this app.

Worse than the original APP
10/30/2026 UPDATE
After using this app since its release, I find it still to be a disappointing app. I have been using a version of this app for years and this version is slow to react, slow to update, and often ineffectual compared to past versions.
UPDATE: Carrier has forced transition to this new app - the older/better one locks users out. Sad, as this one needs a lot of work.
Amazingly, HEAT and A/C can be scheduled, but you can’t include “SYSTEM OFF” as an option during a day’s schedule. (scheduled low fan continues to run)
A “SYSTEM OFF” option would allow savings during “high consumption pricing” hours. (Our pricing for a daily 3-hour period goes from $.068 kWh to $12.00 kWh.)

Cannot even create an account!
It is not able to verify the code it is sending to my email account! I am truly baffled!!!
Was good, now horrible
The original program from a few years ago was good and matches the thermostat UI. Current version is HORRIBLE. Wish I could go back 4years to the original version. Most people hate the current UI.
Painfully avg app for such an expensive system
After paying tens of thousands of dollars for a new furnace and AC, it was pretty disappointing to go from a modern thermostat and app interface like we’ve seen for over 10 years from Ecobee and Nest to this 2003-looking interface. You can’t even rearrange the order of the zones in the app, and forget about any integration with HomeKit. The app also takes some time to sync with the actual thermostats, and it can be unclear when it’s actually been updated.
A surprising pro is the scheduling, which actually is designed pretty well and is intuitive and easy to setup.

Latest version doesn’t open on macOS
After updating to version 1.2.43 app reports: Rooted device. Sorry you cannot access this application. Worked fine before.
You can do better
I have many smart home apps, and this single function captive tool is by far the worst. Do I really need to sign in every time I want to adjust the temperature? (NO) Do I really need to wait 45-60 seconds for the app to sync with the thermostat so I can see the current settings? (NO)
As one of the world’s largest A/C manufacturers you can afford to do better.

Do not buy Carrier
If you happen to see this while still in your return window, return the system and get literally anything else. Cartier is only good for a couple years support before you’re tossed to the worthless AI and nothing will work
Not working anymore
Horrible app and device! Since the last update, when I open up the app it says “Offline”. The thermostat shows it is connected to WiFi, but no connection through the app.
“Lock Display” doesn’t work
Dappas pretty minimal in a way that I like, but one big issue I noticed is that when I try to block my thermostat displays, it says it works but it does not
Good prior to update
Was working fine until latest update, now will not connect to Internet no matter what i do to troubleshoot. PLEASE FIX!!!
Actively Blocked on MacOS… Now…
Used to work fine on my Mac… which was handy… now it thinks my device has been rooted and refuses to launch… Rooted Device Sorry! You cannot access this application.
Why is running on my Mac a threat…. Do better (release a Mac app if you block running the iOS version)

No longer works on Mac OS
The app worked until it updated on its own and now says rooted when opened. Carrier and it’s apps are junk.
App says system is offline
App says system is offline and no matter what I do it won’t change. The wall unit is perfectly functional. I can’t program this at all.
Working again! Just needs an easier vacation workflow.
App is very helpful to manage our Carrier system remotely.
My only frustration was the inefficiency of setting vacation mode. Why doesn’t start time default to now? Why doesn’t the temp range default to my away settings or remember my last vacation settings?
