    What no Lennox iComfort threads?

    I just bought a new Lennox Elite NG Furnace and Heat Pump and was told my Nest was probably not the best option for a thermostat... tech sucker that I am, I went with the iComfort WiFi to replace the Nest.

    I ran into a slight hiccup as the salesman did not realize the iComfort was not compatible with the Elite Series Heat Pumps (yet). The installer made a quick call to Lennox and found out the necessary module is only few weeks out so one of the installers will come back out to finish the setup (they set up the furnace for now).

    I am happy with the iComfort especially when compared to some of the Nest short comings.

    The user can control when and if the iComfort gets firmware updates, whereas the Nest could force an update on you at the most inconvenient time potentially leaving your home without heat if you are away.

    The maintenance band on the iComfort is much tighter making it virtually impossible to feel the temperature fluctuations.

    Although the number of set points per day are fewer (4 to the Nests dozen +) the iComfort allows for multiple saved schedules. This allows you the flexibility to have pre-sets for Staycations, Visitors, Work Week... etc.

    The iComfort has very detailed diagnostics where the Nest has none.

    The iComfort has multiple Hold options (hold to next setpoint, hold for a time limit...etc) whereas the Nest has no Hold options.

    The iComfort has an Away setting that can be turned on via the app or at the thermostat were the Nest had Auto-Away. I had nothing but problems with Auto-Away and had actually disabled it.

    I can't wait to have the Heat Pump brought on-line and eventually having A/C for the first time as a home owner.



    I do have one question for the HVAC pros in the forum...

    The Installer forgot to install the filter before putting the furnace in the test mode.

    The blower is a little more powerful than my last furnace so when I puller the filter out the other day I saw a few dust bunnies in it... Its very possible some previous dust bunnies could have passed into the burner and coils - any cause for concern?

    How do HVAC Cleaning Co's get to the coils once the furnace is in place to clean them each year (down draft furnace)?

    Thank you,

    If the fan only ran for a short time there should no issue.

    The entering air side of coil is where the most of the cleaning needs to take place. If the entering air side of the coil is not accessible the duct work would need to be cut open and resealed or a ductwork access door installed.



    How does the web page of the iComfort compare to the Nest web page? Does the iComfort have energy logs or any type of graphical representation of system runtime?

    Lennox forums have been created. I have also been wanting to add the iComfort to the wifi thermostat buyers guide. If anyone has information about the iComfort that I could use in the buyers guide thread let me know.

    I think what was concerning me was the slight burning smell when the furnace fires up sometimes, but the installer did warn me it would do this for a short time. The thing is it smells a lot like the same smell we got when the blower motor on the old furnace stopped running and the furnace got hot before the cut off shut her down... I am sure it is just normal break in smells.

    Thanks for the explanation.

    The web page, is not quite as refined as the Nest one, but it is functional. The web page and apps lack the ability to set up schedules (but you can change between presets), no energy (run time) logs.

    They have the basic functions such as;

    1) viewing and/or changing the temps (both current and set)
    2) Changing preset schedules
    3) Toggle away mode
    4) control fan settings (auto, circulate, manual)
    5) graphical indication of current running mode (heat, cool, and fan running)
    6) 5 day forecast for the home location.

    Most coils are NEVER cleaned over the life of the system. I've seen 30yr old A-coils still in service that were never cleaned. Condensers just keep getting replaced every few years w/o ever cleaning/replacing the coil. Low airflow then causes liquid to return to compressor, killing it. A 4"+ thick media filter is the best way to protect the coil. 1" filters are either too restrictive or let too much dirt go through.

    Is the iComfort a communicating thermostat? I haven't ran into any.

    Well I know I saw quite a bit of information (telemetry) from the furnace on the installers menu in the thermostat such as fan speed, burner output, voltages etc. and apparently the thermostat will send me (and the HVAC Service Co of my choosing) an email if there is a service alert.

    I am not sure if the module I am waiting for will be able to provide the same level of communication for the heat pump as with the furnace. I know the thermostat only uses 4 wires and one of the four wires is used for passing information back and forth between the furnace motherboard and the thermostat.

    I guess I will hire someone to slide the furnace out of the way every 5 years or so, so that the coils can be cleaned in addition to having the ducts cleaned regularly. My house is built on slab with a down draft furnace so there is no way to access the coils from below.
