Racket to Steal Your Money


Another racket from a decent American company to steal your money. The rule is "HVAC" is generally build on the principle that you must pay to these companies hundreds and thousands of dollars just to bring you the worst technology possible. But hey, I am being "unfair." Anyhu, nothing to add to other reviews, server errors, banality of the unit that they sell it for "$300" and its crappy iOS app. Remember I called a racket? All these things are perfectly known to the corporate. Lennox is a proprietary system. So technically your Nests and Ecobees whatnot are noncommunicating units. You may be able to install them, only if you spend time/money etc, and the results could be good or disaster outs. But your honest hard working HVAC tech will tell you to buy their better S30 or E30 models for $600. Again, they, HVAC companies and techs, hate Nest, Ecobee etc. read their forums. Just sign up for a Lennox tech account and see. How you are swindled. If you own Lennox, you have to deal with these burglars forever. EDIT: after multiple failing units, my gas bill is now 2x. This unit will make sure that you would waste as much gas as possible. Even with their so called multistage blowers.

Functional but...


This review is for both the iPad & iPhone versions:

Rating for iPad version: 3 out of 5 stars:

The iPad version is superior to the iPhone version in that it has a more modern looking UI that is very similar to the actual touchscreen thermostat. All the controls necessary to adjust the temperature, fans, and seasonal programs are available. However, I can't adjust edit the season programs or adjust the humidifier.

Rating for the iPhone version: 1 out of 5 stars:

The iPhone is downright crude compared to the iPad. I cannot edit the seasonal programs. My biggest gripe is the horribly outdated UI aesthetics very reminiscent of pre-iOS 7 elements with respect to fonts and buttons. I would suggest a landscape mode that can more accurately replicate the appearance and functionality of the physical touchscreen.

Whoever is in charge of App Development or Product Management at Lennox either doesn’t give a crap or is constrained by the upper management that doesn’t want to spare the expense to update this app. If the latter is the case, this reflects very poorly on your customer service.

Know in this age of smartphones, the quality (or in this case, lack thereof) of your apps does make/break brand equity.

What’s up with this “as long we have a (minimally) functional app published, that’s all that matters” attitude?

Set back the clock


A decade. This app is very rudimentary & does none of what a modern app should do, such as work with voice commands, Alexa or Siri. It’s far easier to simply interface with the control pad. From time to time it conveniently works to turn the heat on before arriving home but other than that it’s functionality is incredibly limited.. Both the thermostat & app are no better than the 25 y/o version of smart thermostat that was replaced with the new Lennox furnace. Not sure yet, but the thermostat may even be proprietary to Lennox, meaning that I may have no other modern thermostat options? I will be calling the dealer to inquire about that as the furnace was just installed a few days ago and I will certainly ask them to take their thermostat back if a more modern thermostat is available and will operate with the Lennox.
