User reviews

Furnace Rebiew

Don’t really know how well the Furnace is working because the house is either always way too hot or way too cold. The smart thermostat is not user-friendly and very very difficult to understand. Have tried calling for assistance. Assistance has not been helpful at all.

Download every time

It makes me download the app every single time I wanna change the temperature and I already have the app downloaded so then it just says open, but I have to do it every time

APP sucks

Lennox changed thier app and I cannot use on my two year old Apple SE. So why have an app

Rather sell the house than keep this

Never communicates. It’s a nightmare. Paid 20k for this and it never connects to WiFi! It’s a literal nightmare every day to change temperature might as well not be smart.

Terrible

It worked efficiently before the upgrade if you call it that. How is it an upgrade when you add unnecessary time wasting steps to get to the same place?
