4.7 out of 5
App needs more QA

As several others have mentioned, if you have multiple zones, the UII will spontaneously jump back to the first thermostat in your list.

The + and - temp buttons on all secondary zones don’t work. Instead it displays 0 as the new desired temp.

You are forced to carefully use an analog simulated wheel to make the temp change and if you don’t perfectly select the wheel, the ui will panic and scroll back all the way to the first thermostat.

There’s also the caching problem, where it lies to you. Sometimes, you can make changes and it throws them away. So, be sure to go back and check a few minutes later.

Somewhat related to the caching problem, the system will not allow you to leave the fan running all the time. Well the UI will tell you that it’s set to on, but as soon as your next scheduled event occurs, it takes over the fan again and sets it to auto.

So, if you want to follow the guidance of your HVAC installer and leave the fan running 24/7, you can’t use schedules.

There’s no way any executive at the company uses Com. I wonder whose HVAC system they use, I should switch to one that works.

Horrible connection makes app useless

Com can’t log in 95 percent of the time. It says “no internet available” when every other internet-dependent app on the phone is workin great. Like other companies in recent years, there is no practical way to speak to a technician.

Hoping this review will get some kind of response

Nothing but trouble

Hasn’t work since we installed it two years ago. Nothing but trouble. No tech support.

Terrible UI Performance

Com never works immediately. There’s always a massive delay and takes 15-30 seconds to load. Really disappointing.

Automatic settings ARE A JOKE

Either that or I am an idiot after talking to the guy trying to help me - four times.

I have a three zone system. They cannot be individually programmed.

It cannot be done. Unbelievably disappointing. I wish I could use a Nest.

Comfort sync

Com was marginal before I updated Com now it’s almost worthless. It only connects maybe 10% of the time and the away setting doesn’t work at all. I can be right in front of my router and it only connects maybe 1 out of 10 times

So many bugs

Works about 25% of the time.

Poorly Designed & Maintained App

Com is just about useless. Trying to get into settings for any thermostat other than the first one listed is impossible, Com just cycles back to the first unit listed and there is no way to change the order of thermostats. Second Com is just not responsive to anything you put in. Developers need to get it working or replace our thermostats with something that works and quit selling homeowners on a product that does not work.

The connection gets dropped too much

In my 20yrs of owning my prior thermostat that was hard wired to the furnace, I’ve had to cycle power to it zero times in that 20yrs to re-establish a “connection”. In the 4 months I’ve had this new thermostat, I’ve now had to cycle power twice to re-establish a connection. #disappointed Additionally all my TVs are of the streaming variety now, and I’ve never lost a connection more than once per year, so save me the poor wi-fi explanation.

Help!

Just how do you get help? I can run the thermostat if I log into safari on my phone but I can’t log into Com ! Called the number to talk to someone, they had to give me another number. That person had no idea how to help me. Don’t you have a software tech? I was told to call my installer. Are you kidding? It’s your app. And don’t tell me to uninstall Com . Com already has all my info from when I registered. You can’t permanently uninstall an app. When you install it again it brings back all the previous information. I have tried it a dozen times. I have tried changing my password a dozen times or more. Who can help me???

Bad update

The Com worked OK until the latest update. Now it goes back to the first thermostat when you have multiple without excepting the temperature change. Have to exit Com and go back in multiple times. In order to change multiple thermostats. Latest update is a dud!

Loading issues

My two issues are it takes too long to load my three thermostats and my floors are not in order with no way to change them.

Works with effort

It will not sync with thermostats. I have to restart Com to adjust the temperature. Even after restarting, it takes numerous attempts to change the temperature.

Needs more flexibility

Needs more flexibility to be as good as my old EcoBee. Needs to let the user add more trigger times, as Com only allows 4. (EcoBee allows many more). Needs to be able to turn off the gradual heating between trigger times so the user can actually control the temperature precisely.

Will changes stick or not?

As others have said, Com is handy when it works. Changes I make to the simple temperature or mode, or to a mode’s schedule, often don’t actually take — especially, ironically, when I make them within my house! It seems to work better when I’m away from home. The navigation on Com (including on the wall unit) has never been great , but I can get past that if Com would just reliably connect.

Apple HomeKit

It would be nice if it was able to be paired with Apple HomeKit.

Two stage

App is great. Would like for Com to show when it is either in two stage or single stage cooling mode. That would put Com in elite status.

Works great now!

Com used to have some serious glitches. Well, someone finally paid attention to the reviews and fixed it. Everything works great now. Com is responsive, all buttons work, and it will even stay on the zone that you were last adjusting without jumping back to the first zone. Way to go guys! Thanks for listening.

Amazing Comfort Ultra efficient

User friendly, Nice screen graphics, My contractor get notified if any alerts are present. Weather status and alerts. System status and More. Thank You Armstrong Air and Bravo Heating and Air for this amazing ultra efficient HVAC system.

Above average

My overall experience with the A3 is great. The connection from Com to the stat could be quicker and more consistent but, if the A3 is connected to Wi-Fi, the updates and the ability to control the system in more than just heat/cool is phenomenal.

The Comfort Sync A3 thermostat must also be connected to your home’s Wi-Fi router before the app can control the settings.

The Comfort Syc (Sync) App allows the user to control their HVAC system from anywhere in the world as though they were standing in front of their own thermostat.
