What's New in Lennox Home

4.70.0123

August 12, 2026

We've been listening. Here's what's new: • Fixed: app crash affecting certain iOS devices.

User reviews

Good … then good for nothing

When the app fails, it fails miserably. On an older iPhone the app eventually reflects what the thermostat reads but cannot make changes.

Confusing interface

This download was a forced replacement for a previous version that matched our wall mounted controller. On this mobile version, I have to go into a separate area of the menu to find the fan control. This app doesn’t have the same functionality that my wall controller has. That was the reason why I selected it. I am totally unhappy with this design interface. But I don’t have any other choice. If you have any other app recommendations, please let me know.

Lennox report sent to me

Stat screen and iPhone app do not agree. Stat shows COOLING and DEHUMIDIFING. App shows only snowflake. On app, in mode screen, dehumidify shows a line through icon.

The report shows the number of hours for heating and cooling. My system has a dehumidification mode. Lennox does not tell me the dehumidification hours. Why Lennox?

Lennox does not read these reviews - shame. They are not interested.

Not good

We just had a new system put in and it’s not working and the people who installed it, Don’t know what’s going on. It’s not cooling the house like we want.

App repeatedly fails

Prepare for the app to fail and no longer allow you to control your system. FREQUENT
app to thermostat control issues. Good when it works… which is not often.
