    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.

    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.

    I finally took the plunge and purchased this fabulous Smart Thermostat. It was sure easy to install and has worked perfectly controlling the temperature I prescribed in the set up. I love that it comes alive when you walk up to it, and the weather is easily available. Love this thermostat!

    Great fit and finish. Snappy software, responsive touch screen, and great app. I struggled with the install since I have never done a thermostat but I reccomemd using the app walkthrough vs the paper instructions. Much better. Love being able to adjust temp without getting up or being home!

    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!

    Nice quality product, easy to install in modern ho

    Overall nice quality/appearance, easy to read display, easy to program with the app and very detailed instructions that cover a variety of potential installations depending on your particular HVAC system. Our existing wiring included a C-wire so I can't comment on the PEK installation. Total install time was under one hour and that included a little repainting where the previous t-stat base was located. The provided cover plate (about 6 5/8" diameter) would have been more than adequate size to cover the unpainted area but I felt the repainting would look better than a large white plate behind the T-stat which is about 4" square at the face and smaller at the base plate. Purchase price was only $80 plus tax when combining Best Buy sale with a $50 utility company instant rebate. A great value at this price. Two suggestions to make this a five star product would be better quality wall anchors (cheap quality plastic makes them hard to push in without crushing them even after predrilling the wall as insteucted) and the app seems to be a little slow to respond to user inputs.

    Replaced Honeywell Lyric

    The house I bought came with a Honeywell Lyric and was good for about a year and a half. Then it seemed to have trouble staying connected with Alexa as well as other wifi connection problems. Finally got tired of it and looked at the favorable reviews of this thermostat and got it. We already have an Alexa show and couple of dots so didn't need the Ecobee model with built in Alexa. Installation was very easy and set up was a breeze. It was easy to connect to Alexa. This has all the eco- friendly and learning features that are in other smart thermostats although so far the weather here has been mild so I haven't had to interact with it much. So far so good.

    I initially purchased the ecobee3 lite since it comes with the without C wire adapter, however during installation I found the C wire was actually disconnected and used it without the adapter. Installation was simple, and configuration was easy via the touch screen and directions on screen. It's be working without issue, and I also have setup the app on my Note 8 and it works great. I would purchase again.

    Good value Smart Thermostat

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    The thermostat was fairly easy to install, both on my home heating/AC system and home network. The instructions provided were excellent. I used the PEK unit and had an issue with the AC compressor turning on with the fan. Ecobee's customer service, via their online chat, was excellent in solving the issue, which was caused by a wire to the AC compressor that needed to bypass the PEK unit. A great feature is the ability to set both the Heat and AC settings automatically rather than 'heat' or 'cool' only settings. My HVAC system has the ability to continuously run the fan at very low speeds but the Ecobee 3 does not have that functionality. It would be a nice improvement if this was offered.

    Very Smart Thermostat

    This is a great product if you want to be able to control your thermostat from bed, or if you just want a thermostat that looks like it is from the future. I had a couple problems setting it up, but that isn’t because of the product. I didn’t completely read the section in the manual that said if you have any red wire it needs to go into the RH slot on the thermostat, so I wasn’t getting power at first, but once I realized, it works like a charm. It’s very convenient to be able to make quick adjustments wherever I am, and I’m sure it will save me money in the long run. If you only have a simple heater setup and you don’t care about built in voice control, there is no need to get the more expensive Ecobee thermostat. This one will do the trick.

    The product is having more features for the best price compared to other company products. It is very easy to install and configure the device by following the instructions. The power consumtion was reduced after installing the device in a smart way by configuring the options.

    Bought this smart thermostat for my new home after reading it was the best for the Apple HomeKit, that being said I had a home inspection and my HVAC unit worked. I switched from an old unit to a smart thermostat and everything worked fine inside the EcoBee app the AC would come on and I could set schedules no problem. My first issue is that I could rarely get it to connect with my Apple HomeKit and be able to control it from my apple devices but inside the Ecobee app 100% no issues which is fine but I primarily bought this product to not have to enter the app. Now the main issue is that I have an older HVAC unit with no “C” wire so I had to use the provided PEK harness so the thermostat would work which in the summer was fine but now in the winter my furnace would circulate air but not heat up. Turns out my gas control valve is also wired to my “C” location and between the gas control valve and the thermostats PEK harness it could not provide enough power to start up the furnace and heat my home. Now my 3 solutions are either to revert back to a standard “non-smart” thermostat which is the cheapest option, run a dedicated low voltage wire just to power the EcoBee thermostat if I would like to keep the Ecobee, or lastly buy a new smart thermostat that doesn’t require the “C” wire at all which from my research is only 1 and it is not HomeKit applicable (which at this point is the same as the EcoBee).

    Easy install thermostat for upgrade

    I purchased this controller for a heat pump system which is 18 years old to replace the original thermostat that stopped working. I give it a 5 star rating because I can find nothing to complain about. Pros: pricing was good for a smart thermostat and the install was very easy. It requires a few minutes to remove the old unit and get this one ready for install, but the app walked me through the install painlessly. Con: the original thermostat had a wiring configuration which differed from the Ecobee models given during installation but the system works like it did originally so I fretted the wiring needlessly while I was installing it. I would buy this product again

    After having an ecobee in a vaca rental unit, we had to get one. Our installation was more than challenging for us but, with the help of our HVAC guy, we got it done! We love the ease of it and having the app on our phones makes it easy to adjust while your away, on your way home or while in bed…highly recommended.

    Current model comes with everything except the 18/5 wire that I highly recommend you purchase before starting the install. Run the freshly purchased wires from the furnace to the desired location that the unit and install the smart thermostat with the pictured items below. I used the blue wire as my C and did not use the workaround included part. This unit also works with Alexa and or the free app from the manufacturer.

    I originally wanted this thermostat for the ability to set the differential temp range between on and off. This was going to help me with short cycling from my old Honeywell thermostat. It did help and has plenty of settings you can adjust. It met my needs 100%. Now the reporting is amazing. You can login and see when your AC or heat was on. It has a history of on, fan on, and outside temp. Then it can provide a monthly report of how efficient your system is. 100% glad I bought this thermostat! Picture is an example of the on off history it can show you; this day was hot and can see how long the AC was on.

    Works great, and easy to install, needed to upgrade from the old programmable thermostat, and this is what I decided on, didn't want a smart thermostat to make decisions for me although with the recent update this one does, need one to control from an app, tells the weather on screen also!

    I use the Apple Home kit eco system at my house so I like being able to control the temperature of my home by using voice commands. I don’t care to use any of the programming options like setting the temp when I come and go or settings for day or night. For me it’s just a way to control the temp by voice instead of using my iPhone app or getting up to change it manually.
