Excellent Customer Support !

Great product

Functions exceptionally well during change of seasons—seamlessly-/bests all other ‘stats on all counts in Canadian climate.

Legitimately hate this system every single day

Worst thermostat I’ve ever used. The schedules seem to mean nothing. The app is not intuitive and 2 years in, it’s still a daily frustration. So much regret that we didn’t do Nest again.

Sadly it almost never works.

Worst EVER thermostat

I have two L40s (also a Trane and Honeywell therms). The Lennox are is not logical or intuitive. The L40s constantly disconnect from my internet and require resetting with the APP. It’s horrible. The APP is NOT LOGICAL to operate. My others are intuitive. I regret getting a brand new (July 26) Lennox system and their thermostats.
