S40

I have always enjoyed Lennox’s products but since I have gotten the S40 and communicating system. I have been extremely pleased. The app is super easy to understand and it gives me a detailed breakdown of my hvac systems usage for the month! Highly recommend getting a Lennox S40 communicating system!

Bad app

I have deleted and reinstalled the Lennox app on my phone many times. I set the temperature on the air conditioner down and it pops right back up to the original temperature.

Save yourself headaches

Nothing but issues with the Lennox home system. Overcomplicated for such an easy concept so you have to spend a week troubleshooting and ordering parts before getting the system back up and running.
