This company over-complicated our system with unreliable hardware. We were promised that by switching, we’d have a lower energy bill. They installed a bunch of cheap low quality android tablets in our walls to communicate with the HVAC systems. Not only does it not work properly, but our energy bill is even higher because the system is running when it shouldn’t be(despite the schedule), or not running enough and overcompensating later. Terribly inefficient. When we try to troubleshoot, support will tell us “looks like according to our chart it’s running correctly” and then ignore us. They’re in Minnesota, so they only see the “live data” through the internet act like it’s functioning, but can’t be here to witness the system not working physically, and ignore us when we tell them so. The sensors they installed are reading wrong, the rooms are cold, the heat is NOT running when it claims to be, and we’ve had nothing but problems. We do not find this company dependable or useful. The worst part is the UI of the app on the silly little tablets. It’s overdone and there’s too much to look at. It might let you adjust temps, it might not. Can’t tell if the tablets are connected to the WiFi or not when troubleshooting, because the tablets are so finicky. It responds to touchscreen way to slow, and you end up double or triple clicking and screwing things up. We’ve had nothing but regrets, and will be looking at hopefully reverting to the ecobee setup we had, which was simple and reliable and still uses an app if you really care that much to use one. I would give zero stars on 75F if I could. Sick of this garbage.

These guys make pre-programmed HVAC and lighting controls that use IoT and the cloud instead of hardwired equipment to adjust air in our offices to the areas where it is needed. 75F offered better indoor air quality management and were faster and cheaper to install than the other large competitors we reviewed, but what made us select them was that they offer better sequencing and thus promise more energy savings. So far we are seeing roughly 35% energy savings, which is 10% more than we expected, and 75F says that should increase in winter months. We have a mix of mostly older equipment and thermostats in the space, and 75F was able to do the install themselves in a few meetings and get our facilities crew trained up on the new software. There was a bit of a delay in scheduling an install which was annoying and they offer a lot of features that seem unnecessary and that we don't need but overall we've been fairly satisfied.
