Carrier, you should be ashamed of yourselves. I have fixed your littered code problems that caused all of my mini splits going off-line all the time. Completely unusable, prior to my fix. Contact me and I’ll be happy to also fix your horrendous app.

This app and the unit are constantly losing connection, meaning I have to reconnect them like it is the first day or even worse, I have had to delete the app and reinstall multiple times. I dislike the app as well as the unit and would encourage anyone considering a mini split based on its operation from a smart phone to look elsewhere.

The old version of the app would allow me to set the heat in FP mode down to 46°. The new version will not go below 60°

I’m not one for writing reviews. In fact this may be only the second or third I’ve done. We bought 4 mini splits about a year ago. The app that Carrier used to have was basic. It worked, but it was very iOS 4 in appearance. Some of the controls were not great, but it worked. Then they updated. The app went from being basic to being garbage. They tried to update the functionality, but in turn have somehow broken connection abilities. Since the overhaul, I’ve reconnected my devices at least 30 times. That’s no small feat considering I have 4 of them, half the time I can’t get the app to find the Wi-Fi network I use, and when I do, they won’t connect half the time so I find myself going through the process 3 and 4 times to reconnect. This evening was the last straw. I came home from a trip (we lost power due to line service) for about an hour, which knocked out the Wi-Fi. I fully intended on having to repair a unit or two. Nope. ALL FOUR. So I did the thing and went through the rigamarole to reconnect them. Low and behold they all connected on the first try. The room name for one wouldn’t take, so I went back in to change it, saved it, backed out and one of the others had already severed its connection. So I did it again, 5 connections now. When I finished that one, the one who’s name wouldn’t save lost itself. I gave up. They weren’t staying paired for more than 30 seconds. That’s why I’m here. Carrier is a $40 billion company. You can make a better dang app. If you do, maybe I’ll add to this review. At the very least give me back the old one. Also there’s a lot of people I’ve found online with the same pairing issues, but no fixes from carrier I’ve read about. Go figure. Take this into consideration if you’re thinking about a Carrier product with Wi-Fi.

It is so frustrating that the system often goes off-line and there’s nothing I can do about it remotely. We specifically bought the system so that we can adjust the temperature remotely especially when we land or rent the house out to others. We are left blind and ultimately need to drive all the way to our house (hours away) to check on the system. Carrier please get your act together and fix this. We have confidence in your product, but that confidence has extinguished fairly quickly. And now the app does not allow me to switch into frost prevention mode. Carrier gets a big F.

Just had to say thank you to the devs and carrier for updating this app to 2.0. The UI is SO much better. There is increased functionality, for example I can now “boost” mode from my phone, that was not there before. I also love the added functionality of the specific positioning angles (BOTH up/down and left/right!). If you didn’t like your experience with the previous version I would definitely give this app a try again, I think carrier and the devs put in some quality work into their update and I’m thankful because I can be even lazier and not have to get the remote for my split system. I hope they get more nice reviews for this update they deserve it.

The most essential piece is broken. We can’t login. Great job!

I have a minisplit A/C unit that functions fine but I wish the app could disable the chime on the unit. Not necessarily a reflection of the functionality of the app but more so a design flaw within the wall unit itself. Just hoping the app developers could code something to turn off the loud chime as I adjust the temp from my phone at night in our bedroom.

Wow, the new version looks great and so far works really well, thanks for the update.

Very poor app . Basic not much tech. Keeps logging me out of the app no way to “ stay logged in” Says humidity but actual is way different. Wish they would update this App my mini split is only 1 year old and I added the Wi-Fi module .
