The update from 1 week ago has not fixed the problems! App still won't adjust the temperature to what I've set it ti be.
Called Lennox-no help!
Had our repairman out who said it's a problem with the app.
Why doesn't Lennox listen? Don't they want satisfied customers??
Please listen to your customers that you forced to download this awful app!!!

Horrible app

I was forced to update to this app from iComfort, and I can’t even use it. When I try to login in with my account, the screen doesn’t allow me to enter a login and password. So now I can’t control my thermostat at all. And of course, the iComfort app now just has a page insisting that I install this app that I can’t use. Simply awful.

Two broken within 2 years of use

I installed Lennox 2.5 years ago, since then two broken parts happened within 2 years. One is the relay switch in the condenser, and the thermostat suddenly not functioning. Poor reliability for such an high end product.

App Always Updating

Every time I open Lennox Home it asks to update. Every time.
