unable to use

app crashes and keeps showing “unauthorized system access detected” any fixes for this yet?

Work yesterday today Not

App work excellent yesterday, today suddenly said my phone Jailbroken not allow to use app, my phone is very original and legal, updated app no help, still say samething

Interface

Clunky onboarding won’t recognize employer from zip code. App wants to monetize data before you can even try it to see if you like it.

No longer works

I have used this app for 2 years almost daily and now it won’t even let me log in saying I have the wrong iOS but my phone is updated to the newest iOS.

App not working

Tried to use this app on iOS 26.5 and it says my phone is jailbroken which it’s not.

Unable to work

The app claims that it is unable to work with my phone due to being “jail broken” even though my phone is not. It started after the update. Now I can no longer use the app

App not working

Tried to use this app on iOS 26.5 and it says my phone is jailbroken which it’s not.

Not connecting from old control board to new control board

I spent 2 hours trying to replace a control board and trying to connect to the new board. Whenever I would “tap” to connect it would say an error has occurred. Then I manually put in whatever I needed and I would “tap” to connect to the new board and it would say an error has occurred. Why would you have to program a new board with an app when in the past companies would just use dip switches? I had to leave the customers house with no heat because this app would not connect to the old or new board.

Response from developer

Hi Denis, we're sorry you were left in that situation with no heat. Control board replacement workflows are a top priority for us right now. Please email us at digitalAppAdmin@carrier.com with your board model numbers so we can escalate this to our engineering team.

Terrible

Everytime I have to use this app even if it’s 4 times a week I have to update it and put my password back in. Yet nothing ever works better.
The NFC tag can take 20 tries to work on a furnace. The barcode scanner on a furnace won’t bring anything up. Manually entering model numbers won’t do it.
It’s just a constant fight, then after you get it to work it’ll just say they don’t have any parts data on that 5 year old carrier. Unacceptable.

Hi, these are real issues and we take them seriously. Please email us at digitalAppAdmin@carrier.com with your specific equipment details so we can investigate.

NFC NEVER WORKS

Tried countless devices with countless control boards and it never connects. Even tech support doesn’t know how it works

Response from developer

Hi Aaron, NFC reliability is a known issue we're actively working on. Please email us at digitalAppAdmin@carrier.com with the specific control board models you've tried so we can investigate.

Can’t even create a username

Attempted to create an account and tried 20 different usernames that all took minutes to verify and have still not been able to find a username that’s not been taken. Super slow and couldn’t even create an account.

Longest wait times at ALL locations

Carrier is the worst when it comes to wait times in all of their dfw locations. Expect to spend a minimum of 30 minutes even if there is no line ahead of you and you’re simply trying to pick up a motor. Ridiculous!

App is awful

The app is so slow and awful. Especially connection to these new smart boards. I have to retry multiple times when connecting and saving the new changes to the board. Very aggravating when you’re in a attic and it’s not working

Response from developer

Thanks for your review. We're sorry to hear about the slowness and connection issues you're experiencing with the smart boards, especially when trying to save changes. We understand this can be very frustrating. Please reach out to us at digitalappadmin@carrier.com with more details about your experience so we can understand what happened and help.

Senseless complications

HVAC TECH HONEST BRAND REVIEW:
The Worst Company in HVAC – Avoid Carrier at All Costs

As an HVAC technician with years in the field, I’ve worked with just about every major brand. Let me be very clear: Carrier is hands down the worst when it comes to serviceability and customer experience.

Their control boards are intentionally designed to be a nightmare. You can’t just replace them like every other sane manufacturer allows. No – Carrier forces you to:
1. Download their bloated, pointless app
2. Become an “authorized dealer” (even if you already are)
3. Create an account in their system
4. THEN wait up to 72 hours for approval

Meanwhile, my customer and his family sit in a sweltering house with NO A/C, all because Carrier wants to lock techs into their walled garden and control every repair. This is not just inconvenient – it’s completely unacceptable.

This system is a disgrace. It’s not about safety or quality – it’s about gatekeeping and greed. If anything breaks on a Carrier unit, your customer is likely to be without heat or cooling for DAYS. In the middle of summer or winter, that’s not just an inconvenience – it’s dangerous.

NEVER buy Carrier systems. Tell your friends, tell your family, tell your customers: choose literally any other brand. Carrier has lost all respect in the HVAC community, and they’ve earned every bit of the backlash they’re getting.

Helpful Information

This app provides helpful information for techs. I use it to look up documents for a unit, see warranty and to see data for a connected system.

Pretty Slick

Used to work for Trane but left because of the problems I had with their technology and how long everything took, now on the residential side and this app is light years ahead!

Saves time for new techs

The NFC features save time for me and my new techs as we no longer have to access the switch boards

Pocket assistant

Great app.

iPhone nfc

iPhone nfc compatibility seems to not work when try to use the new install feature to adjust blower speed or when swapping out a faulty board

Response from developer

Thanks for your review. We're sorry to hear you're experiencing issues with iPhone NFC compatibility when using the new install feature for blower speed adjustments or board swaps. Please reach out to us at digitalappadmin@carrier.com with more details about your experience so we can understand what happened and help. If you could provide your phone's model, it'll help us better provide the needed support.

Perfect

Did my job on time.
