It goes offline or completely dead randomly. I have had Nest thermostats in other homes that don’t have these issues. Basically this is unreliable. ### 2/5 — It rarely works! *2026-05-26, version 3.96.016* It’s just ok, this app needs a lot of work. It rarely works before you get frustrated and don’t bother. It would be wonderfully convenient if it did but constantly has a hard time connecting to the thermostat. Frustrating as heck!! ### 2/5 — Disappointed *2026-02-22, version 3.96.011* While the system is fancy, we’ve been plagued with technical problems with the software and hardware. I wouldn’t but it again. ### 2/5 — Loss of communication *2026-02-12, version 3.96.011* When everything is working this app is great. Seems about every 5 months the system fails to communicate in some fashion. I called the first time the system failed and spoke to the Lennox idiot and they told me to call the installer. I decided to treat the system like any other piece of tech that stops functioning as designed and did a hard reset by cycling the circuit breaker. Turn off wait a minute and re energize the system. Normal operation was restored. Twice early on I had to re enter the system password to regain control of the system. For the money I put out I had higher expectations. The system heats and cools excellent when it isn’t falling on its back side. ### 2/5 — Pretty buggy *2026-02-08, version 3.96.011* Sometimes it works ok sometimes it doesn’t ### 4/5 — Keep this app! *2026-02-06, version 3.96.011* Stop trying to make Customers switch to the new Lennox app “home” which is terrible! On the new app, you can’t toggle between systems! Keep this app, it’s great with the one exception that you ask me daily to switch to the terrible Lennox home app! Try to toggle in between systems… you can’t!!! ### 2/5 — Can’t set schedules *2026-01-17, version 3.96.011* Asks too much personal information, can’t set schedules, can’t customize anything. Setup takes a long time — you’ll be poking at the thermostat screen and entering passwords when they could have just made a QR code. Useless! ### 4/5 — It works, but it keeps asking me to download a different app *2026-01-14, version 3.96.011* OK, so now I have two Lennox apps on my phone that do the same thing. Not sure why. ### 3/5 — No renote access *2025-12-28, version 3.96.011* I can never access remotely ### 4/5 — Good app *2025-12-10, version 3.96.011* Not bad, user friendly, much better than the new one they released. Only issue is it’s very slow to connect even when on the same WiFi network. ### 2/5 — Costing us money *2025-12-05, version 3.96.011* At some point Lennox removed the ability to turn off the fan . Now it circulates at a minimum of 9 minutes per hour. Thus jacking up our electric bills and wearing out motors faster costing us more expensive repair bills and bolstering their bottom line selling parts. Please provide the ability to turn the fan and not circulate. ### 1/5 — Apps stopped working *2025-11-10, version 3.96.011* App stopped working, we reset the main wall screen and delete the app and reinstall, did not help. Weak support communication as well ## Most critical reviews (10 lowest-rated) ### 1/5 — Garbage dated app *2026-05-22, version 3.96.016* Made by geezers who wrote this app in COBOL ### 1/5 — Awesome *2026-05-20, version 3.96.016* Very easy app to use very convenient too ### 1/5 — Lennox is Horrible *2026-05-09, version 3.96.016* I will NEVER buy Lennox again! Also Superior Air in Utah is HORRIBLE. ### 1/5 — Horrible App *2026-03-29, version 3.96.011* Zero ### 1/5 — Dishonest rating *2026-03-25, version 3.96.011* There is no way that Lennox has 45k reviews of this product let alone one that would warrant such glowing feedback. No other HVAC company is remotely close to having the number of reviews. Is obvious that they are manipulating the App Store to inflate positive reviews. This app is completely abysmal. They rarely updated or incorporate user community feedback. ### 1/5 — Terrible App *2026-03-12, version 3.96.011* If Lennox set out to make the least user-friendly app ever, they nailed it. ### 1/5 — Terrible app *2026-01-31, version 3.96.011* Can not believe how terrible this app is. Simple things like changing the temperature take forever given the slowness of the app. ### 1/5 — Frustrated *2026-01-26, version 3.96.011* Remote does not slays work. Can’t change temp or schedules remotely. ### 1/5 — Record time in dehumidification mode. *2026-01-21, version 3.96.011* Record time in dehumidification mode.?? Monthly run times are posted for cooling and heating. Nothing is posted for 1st and 2nd stage cooling nor for times in dehumidification mode. ### 1/5 — Waste *2025-11-30, version 3.96.011* Worst thermostat out there! Don’t waste your time with it. ## Most praised reviews (10 highest-rated) ### 5/5 — Reassuring *2026-04-18, version 3.96.016* Worked to protect my house from afar during a brutally cold winter. Reassuring to know I could minimize and even avoid damage to pipes and all the possible damage that could occur during multiple days of below freezing temperature without being there. ### 5/5 — IComfort is better than Lennox Home app *2026-04-05, version 3.96.011* The Lennox iComfort app has all the detailed system operational features of the actual Lennox thermostat. The “updated” Lennox Home app dropped some of the operational options & has a less user friendly interface. For example, the option to select fan operation mode for each programmed cycle is available on the thermostat AND on this iComfort app…but NOT on the Lennox Home app (which only allows fan settings for an entire global program). This is the better app to use. ### 5/5 — 80% but reliable *2026-03-23, version 3.96.011* I have had this system since 2021 and I am mostly satisfied with it. The connection has some issues at times but it’s mostly reliable. My biggest complaint it the lack of a fan mode and lack of manual override controls for the fan speed. Especially in “window season” this would be super helpful to have. ### 5/5 — Dependable *2026-02-23, version 3.96.011* 10 years of reliability ### 5/5 — A pleasure to use *2025-12-20, version 3.96.011* Had this for years. Never gave me a problem. A job well done. ### 5/5 — Do NOT switch to LENNEX HOME !! *2025-12-07, version 3.96.011* Some brilliant engineer or stupifizer thought they had to CHANGE something because of their Title. DO NOT SWITCH TO lennox home, for the S30 thermostats !! It’s USELESS. ### 5/5 — Great Tech Support *2025-12-02, version 3.96.011* I updated to the latest version of the thermostat and I inadvertently knocked myself off-line. I tried 100 times and I couldn’t get back on. The support person was Shamia. She was extremely knowledgeable, demonstrated patience and courtesy and made me feel very comfortable, asking as many questions as I did and she got me working like brand new. ### 5/5 — Cooling and heat *2025-11-23, version 3.96.011* Very useful!Works great! ### 5/5 — You will wonder why you took so long! *2025-10-31, version 3.96.011* So worth it! You can control temp always when traveling or even when lying in bed and don’t want to get up and you know you are looking at your phone anyway:) Love it! ### 5/5 — Great for convenience *2025-10-12, version 3.96.011* All around wonderful app that makes it extremely convenient to alter your thermostat settings on the go. The range is also extremely useful and is a wonderful way to help save energy without letting temperatures change to drastically while you’re away from home.
