Being using for months and can never figure out. Plus the font for most important info- the temperature - is tiny! ### 3/5 — App not working since update. *2026-08-11, version 1.2.38* Since the last update I’ve not been able to control thermostat from my IPhone. Keep getting message Offline. I can control from thermostat but not my phone. ### 4/5 — Great app, but missing vital hybrid scheduling options! *2026-08-06* Great app, but missing vital hybrid scheduling options! I love my premium Carrier Infinity 27VNA0 variable-speed heat pump systems, but the app is missing a huge optimization feature for multi-story homes. Right now, "Hybrid Heat" only switches between the heat pump and the gas furnace based on outdoor temperature balance points. We desperately need a scheduled "Heat Source Override" option inside the Comfort Profiles / Scheduling wheel. I want to be able to schedule my downstairs unit to switch to "Gas Heat Only" automatically at night during the winter. This allows the hot furnace air to rise naturally and heat the upstairs bedrooms, keeping my larger 4-ton upstairs heat pump completely idle while we sleep. In the morning, it should automatically switch back to "System in Control" for daytime efficiency. Currently, I have to manually tap through the menus to do this every single night and morning. Adding a timed fuel source selector to the scheduling wheel would make this app perfect for modern utility rate structures and multi-story homes! ### 2/5 — System status in never correct *2026-08-03, version 1.2.37* Hot day. System cooling at 100% according to the wall mounted thermostat. iOS app says it’s idle and detailed status says the system is off. Been this way for years. ### 2/5 — Can’t add COR Device *2026-08-02, version 1.2.37* I have COR thermostats throughout my house and I don’t have an app to control them with other than Apple home. Please add a way for me to register and add those thermostats to the app or some app please. ### 2/5 — High Cost equipment, low cost app *2026-07-31, version 1.2.37* Spent a lot of money for my top of the line carrier infinity AC unit but the app almost never shows current thermostat settings. Seriously lags. Very disappointing. A top of the line HVAC system should be paired with a top of the line app. ### 1/5 — Can’t setup unless auto *2026-07-29, version 1.2.37* This app is Aweful. I want to be able to set my house schedule. I have to put in a range and we sweat our asses off. I should be able to select cooling or heating not auto. We are so uncomfortable, I either have to set it to a temp a hold. Even when not home. Who doesn’t love wasting money or feeling uncomfortable. Those are my only choices. DO NOT buy a carrier unless you bridge it to a 3rd party app. ### 1/5 — Awful App *2026-07-22, version 1.2.37* I hate that I have to use this app. The NEST APP plus the nest leaf is much more efficient and the dashboard shows all the icons on the NEST APP! This CARRIER APP IS AWFUL! ### 2/5 — Missing functionality *2026-07-20, version 1.2.36* Very simplistic. Scheduling functionality is limited. Cannot pick a specific schedule. Fan control should be easily accessible. Needs to display system load percentage. Fan status. ### 1/5 — Constant problems *2026-07-19, version 1.2.36* All need to be fired. Never works. Constant problems ### 1/5 — Problem to connect to data server *2026-07-16, version 1.2.36* Always have problem to connect to my infinite data server. ### 3/5 — Carrier Infinity Control Module *2026-07-14* The Carrier smart app and and HVAC system control panel is not friendly to use whatsoever. I previously owned a Honeywell control system panel with iPhone app, and it was 1000% better and easier to use. The Carrier HVAC system seems to be a good heating and cooling system, but the control panel is the worst!!! The Carrier HVAC system was installed 12 days ago, and I am already having issues with the smart app. It is already showing it is offline, and I cannot get it back online. I am contacting the company that installed the Carrier HVAC system to see if they can reinstall the old Honeywell control unit with its iPhone app. This is so frustrating since I just spent a large sum of money on the Carrier system. Huge Regrets!!!!!!!!! Carrier needs to develop a new control panel and a new smart app!! Terrible design , absolutely terrible. ### 1/5 — Not every day is the same *2026-07-13, version 1.2.36* This app relies on the creation of profiles for activities ie awake, home, sleep, away, but these settings bury a simple fan speed change under these layers. Selecting cool mode doesn’t give you access to fan speed, only what temperature you desire. Well without adjusting fan speed the system can’t achieve this in extreme heat. I don’t want to boost the fan speed for every day. JUST TODAY! Either make the system smart enough to recognize when it needs to boost fan speed or give better access. ### 1/5 — From bad to worse *2026-07-11, version 1.2.36* This app has never been fully functional (usually 1 of our 2 zones is always “offline”). But after this most recent update, both zones are offline, rendering it completely useless. ### 1/5 — Worst device for smart homes *2026-07-11, version 1.2.36* Just a bad device for smart homes. Doesn’t connect to any of my automations. Go with a nest or ecobee. Much more smart home friendly. ### 1/5 — By far the worst HVAC app *2026-07-05, version 1.2.35* This is a terrible app. There’s nothing I can say good about it. As example, this app does not allow two critical functionalities. You can only set temperature zones and not a specific temperature setting. The status of the unit always says idle even when the unit is heating or cooling. The app is just so bad that I’m actually thinking about spending the extra couple hundred dollars to replace the controller to get a different app. ### 2/5 — Nonintuitive Display *2026-07-02, version 1.2.35* The screen is nonintuitive. The large main numbers should be the actual room temperature. The “setting” should be the small number. Go look at Trane - they have a better app. ### 1/5 — App *2026-07-02, version 1.2.35* The new app completely doesn’t work. My controller is connected to internet and the app says it is not so it can’t connect to the updated app. Totally useless IMO ### 2/5 — Bizarre Interface *2026-07-01, version 1.2.35* Looks like it was written in the 80's. Arcane interface reminiscent of something written 20+ years ago, and definitely not "smart". 30K for this Infinity system and this is the best they could do? The thermostat itself is just as stupid. ## Most critical reviews (10 lowest-rated) ### 1/5 — Absolutely horrible *2026-08-18, version 1.2.39* 1.2.39 the garbage continues. Clearly not a sole is testing. Made a change at the wall controller and subsequently received 35 notifications over the next 4 hours that I made a change. Good grief. Can someone please test before releasing. The qty of bugs, broken functionality and lack of features is astonishing. 1.2.38. Absolutely terrible. App does not communicate with wall controller. Wall controller shows fully connected to WiFi and all servers. Another trash release. When is @carrier going to get real developers and fix this trash app. Expect more from a $20k system. What a joke. 1.2.35. Still have not fixed the most basic of items. What is my system doing? Wall controller on WiFi and all servers connected. Wall controller says cooling. Your “smart” app says idle. Your crack AI chat bot is useless. Request for tech support goes unanswered. @carrier your need to fix your trash app. This has been going on for g on for way too long. 1.2.34 is total trash. Nothing in the app is reflected on the wall co troller. WiFi connected and operational. Your new BOT help is useless. Submitted help request 3 weeks ago no reply. I am done with @carrier Absolute worst garbage. App shows my system is “off”. Wall controller shows it in cooling mode(can see on security camera) Now I need to drive 2 hours each way to reset system by killing power. What’s the point of the software to remote monitor? @Carrier fire every software developer and fix ur trash this has been going on since you released your “SmartHome” app. Not very smart is it. 1.2.33 now app either does not load or takes over 1 minute to show data. What trash. (Yes have deleted and reinstalled) 1.2.32. App continues to be trash. Let be be clear. Connected to all servers and WiFi. Your app IS NOT IN SYNC WITH WALL CONTROLLER. HOW LONG ARE YOU GOING TO TAKE TO FIX THIS. GET NEW DEVELOPERS. 1.2.31. Yet another trash release from @carrier. At least they are consistent. Wall controller shows heating. App shows heating and idle. Operating status in app shows everything off. What garbage. 1.2.30 yet again another trash release. PLEASE FIX the most basic of items. THE WALL CONTROLLER IS NOT IN SYNC WITH THE APP. HOW HARD CAN THIS BE TO FIX. TRASH!! Once this is fixed I will enumerate the dozen other broken items 1.2.29 Yet another joke of a release. Wall controller shows fan off and gas off. Card shows heating but idle. How in any way possible does this garbage get thru QC. I can explain. There is not a shred of quality control @Carrier. Garbage release. @Carrier get ur act together and put some quality into your work. 1.2.28. Not sure what bugs you are fixing but the crack team @carrier has yet to fix the most basic of bugs. What is my system doing? Wall controller shows 55% gas heat. Card shows idle and status and usage shows no gas heat but fan on Who is asleep at the wheel. Fix ur trash @carrier. 1.2.27 yet another embarrassment. Get another dev team. Clearly this team cannot fix wall controller and app not being in sync. Wall controller clearly shows 40% gas heat. App says idle. Clearly no one is doing any sort of QC. Stay away from @carrier 1.2.26 same trash as before. Most basic of functions don’t work. ?what is my system doing? Nope wall controller and app not in sync If your “listening” fix the most basic. WRONG STATUS Changes from app not /infrequently reflected on wall controller “Smart” what a joke. Not worth it. Toss the app and start over with folks that know what they are doing. EMBARRASSMENT. 1.2.25 yet another trash release. wall controller shows fan on with 40% gas heating. (Visually confirmed and correct. ) Status and Usage in app shows fan on but gas off. Card shows heating but idle. How in all that is good is this possible.? Clearly not an ounce of QC. But they did add the ability to not show the weather. Stop with the lipstick on the pig and fix the pig. Just HORRIBLE TRASH. @Carrier you should be ashamed to release this junk ### 1/5 — Don’t bother … *2026-08-15, version 1.2.38* Carrier may manufacture great hvac and heating systems, but their app onboarding is infuriating. The manual doesn’t even tell you which app or QR code to scan - so the customer is left to guess, download an app, create an account, and then find out it’s the wrong app without the aforementioned wrong app telling you which app to use ! Reinstalled my Nest Gen 3 … ### 1/5 — Off line again *2026-08-15, version 1.2.38* Was working for awhile but app now shows furnace offline(it’s not) and will not connect ### 1/5 — Wifi impl sucks *2026-08-14, version 1.2.38* device is offline most of the time. garbage device and app. smart? not even close. ### 1/5 — Cant even verify my gmail how am i supposed to create the account *2026-08-07, version 1.2.38* Cant even verify my gmail how am i supposed to create the account ### 1/5 — Infinity Units are unserviceable *2026-08-06, version 1.2.38* The corporate level bean counters at Carrier have stopped production of key components to the HVAC unit. My infinity is 3 months out of warranty. Has been a lemon from the get go needing new compressor and inverter. The inverter has failed again and what should be a $600 part now is quoted as $8000 from my HVAC installer. It can be found used on eBay for cheaper. This is an example of how they want to force a new sell on you. Never buy carrier! ### 1/5 — From bad to worse *2026-08-05, version 1.2.38* This app has never been fully functional (usually 1 of our 2 zones is always “offline”). But after this most recent update, both zones are offline, rendering it completely useless. Every update is the same in that the app still never works and says that both units are “offline.” ### 1/5 — Terrible App *2026-08-03, version 1.2.37* This app is simply terrible. It glitches often and lately most of us users have gotten the “Offline” message. There’s no way to troubleshoot and get rid of it. I’ve deleted the app from my phone together, re-installed it, and I’m still getting the “Offline” error. What’s the point in having a smart thermostat if the app used to control it doesn’t function correctly and the only option to operate the thermostat is manually from the wall? 🙄 Get it together, Carrier. You’re too large and reputable of a company to have such a poor performing subpar app that’s highly unreliable. ### 1/5 — Remote control sucks!! *2026-08-01, version 1.2.37* We have the “ultimate best 2 Cartier HVAC” units and Wifi connection works on one but 40% or so is out on the other unit. The WIFI signal is strong by both for many months with no solution by Carrier - ### 1/5 — Doesn’t sync with thermostat *2026-07-31, version 1.2.37* The app does not show the same information as the thermostat. You can turn on your cooling system, and half an hour later, the app will still show the system as off. It will also not have the same temperature or humidity readings as the thermostat for extended periods. How hard is it to sync an app and a device nowadays? Really poor effort by Carrier. ## Most praised reviews (10 highest-rated) ### 5/5 — Carrier Infinity wall control *2026-07-17, version 1.2.36* Excellent app. Easy to set up. AI help nailed it with my only question. Well done! ### 5/5 — Update broke it but it’s back! *2026-05-24, version 1.2.33* Was working just fine until the latest update took the app offline. Thankfully, I hadn’t been using it recently. Why don’t developers leave well enough alone? Update - app is back online!! Thank you! ### 5/5 — This needs to be tested before releasing it to owners. *2026-05-09, version 1.2.32* Frustrating pile of junky code. ### 5/5 — works *2025-12-19, version 1.2.24* After a VERY FRUSTRATING initial setup last year with very poor support, the app is now working flawlessly. Have now used it several months without any issues. ### 5/5 — Carrier Home *2025-12-11, version 1.2.23* Great update ### 5/5 — Significant Improvements *2025-10-18, version 1.2.21* Much better app since modifications were made to the app during the last several updates. Well done, Carrier! ### 5/5 — Great App Overall *2025-10-18, version 1.2.21* I rely on this app almost every day. It’s great for adjusting temperatures on the go; checking system status, and setting vacation schedules when I’m traveling. The energy insights feature is particularly helpful. I’ve been able to lower my utility bill by making small changes based on the data. The only thing that occasionally bothers me is the auto log-out after updates. It doesn’t happen often, but when it does, I have to reenter my credentials. Other than that, the app has been stable and easy to use. ### 5/5 — Carrier Nailed It with This Version *2025-10-17, version 1.2.21* I was honestly skeptical when I first installed the app a couple of years ago, but the improvements over time have been impressive. The onboarding process was straightforward. I connected my system in minutes. Once set up, everything just worked. The UI is modern, and I love how clearly it shows system performance and energy usage trends. I also appreciate that it doesn’t bombard me with unnecessary alerts. I use it daily to manage multiple zones in my home, and it rarely fails. This is exactly the kind of experience you expect from a major brand. ### 5/5 — No longer works - updated works now. *2025-09-12* I have been using the app on and off for years including this newest version. Well as of this week I can no longer even login or connect. Just get a 404 error and then it asks to contact support, yet no email or number just trying to use the default mail app off of my iPhone. I don’t use the default but no other option. I may just have to look for a different thermostat and app. Update- the app just started working again. It works like it always has which is perfectly. Whatever the devs did, thank you. **Developer response:** Sorry for the login and 404 error you’re seeing. Our team is investigating the issue. In the meantime, please contact us directly at ResDigital@carrier.com so we can help get you connected. ### 5/5 — App crashes resolved with app reinstall! *2025-09-09, version 1.2.20* Thank you Carrier! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
