    Excellent thermostat

    I did a lot of research and I was going to get a Nest, but the HVAC company that we have been working with recommended Ecobee. Before getting any smart thermostat, please check your furnace for a C wire. My thermostat setup had the humidistat right below it. The wall plate the came with the Ecobee Smart Thermostat was big enough to cover the thermostat and humidistat holes. The HVAC company installed it for me. If you are not familiar with installing thermostats, please have an HVAC company install it. After installation, I was ablE to program it through the app. There is a sensor built into the thermostat and it comes with an extra external sensor, which I put in my office. I am able to see what the temperatures are in each room. After a good furnace cleaning and thermostat installation, My HVAC is working better and I have better control over my heating and cooling. With Alexa built in, I moved my Echo Dot into another room. The speakers on the thermostat are awesome for a small device. I used some wall paint to touch up where the old thermostat was. I plan on painting the walls next summer.

    Needs C wire, good thermostat but mot very smart

    While it is very easy to use and works okay with Alexa (its very temperamental with hiw you say the command) i dont think the thermostat is very smart. In my opinion i wouldnt buy it again. Its a lot of money for basically a pretty thermostat that works with Alexa. I could have paid a lot less. Also very important it needs a C wire. It doea come with a adapter if you dont have one like me. The instructions to install the adapter are auper easy as long as you can easily access your furnace.

    MOVE TO SIDE NEST!!!

    Had one hang up during installation, as my HVAC unit did not have a C-Wire in use. Ecobee Customer Service was one of the BEST I have ever experienced! (6 Stars) Called the help-line, on hold less than 2 minutes, and they had an easy solution for me in 5 minutes... and checked back afterward via email to make sure the thermostat was working! Ecobee 3 Unit is very user friendly! Also, my electric bill dropped almost 30% in the first month! Can’t recommend this purchase enough!
