### 1/5 — S30

*2026-08-25, version 4.70.0123*

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!!!

### 1/5 — Horrible app

*2026-08-24, version 4.70.0123*

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.

### 2/5 — Two broken within 2 years of use

*2026-08-24, version 4.70.0123*

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.

### 1/5 — App Always Updating

*2026-08-24, version 4.70.0123*

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

### 1/5 — Terrible app

*2026-08-21, version 4.70.0123*

Hardly ever works and when I leave
My house it shuts my
System
To
Away automatically and the house is hot an hour later when I get home

### 1/5 — Remote Control Never Works

*2026-08-21, version 4.70.0123*

After six years and many man service calls, the Lennox Home app has never been functional unless we are on premises. We’ve called Lennox. We’ve called local Lennox representatives. We’ve had many of them at our home and none of them can turn this into a reliable solution for someone who needs to control temperatures remotely at a second home. The worst part of this Lennox acts like they don’t even care. Because we have presidential series equipment we must have the Lennox thermostats but ecobee worked far better elective to remote access.

### 1/5 — Poor app

*2026-08-21, version 4.70.0123*

Lennox keeps asking you to download the new app even after you have installed the new app repeatedly.

### 5/5 — Thermostat

*2026-08-19, version 4.70.0123*

Won't let me set it at 75 degree's only 74 or 76

### 4/5 — Fan options

*2026-08-19, version 4.70.0123*

Overall good app, just problems switching fan options on iPhone 17 pro. Usually have to tap it 2 to 3 times to switch to selected option.

### 3/5 — Great when it connects

*2026-08-17, version 4.70.0123*

More often than not it is offline and cannot connect. I was gracious and gave it 3 stars but 90% of the time it won’t connect.
