I was never happy with my Nest thermostat and learned about Ecobee while reading complaints by other owners of Nest thermostats. It has wireless "sub-sensors" that you can put in other rooms and the Ecobee will read those sensors and average the temp in the house, or, I put one in the master bedroom and have the thermostat work off of only it at night. Our bedroom is now comfortable all night – instead of the hall way where the Ecobee is installed.
Ecobee gives you a LOT of reports, including inside and outside temp and humidity, Heat setting, Cool setting, HVAC Fan and actual inside temp, all on one graph so you can see how your system is working and performing. And, it will give you history all the way back to installation. Unlike Nest that only goes back 10 days.
Installation was easy. The app tells you to take a photo of the existing system and then tells you where to connect the wires on the Ecobee. It took 15 minutes and that was double checking all of the instructions.

I’ve been extremely happy with the ecobee Smart Thermostat Premium. Installation was straightforward, even with an older system, and the app walked me through everything step by step. Once it was up and running, the difference was noticeable almost immediately.
The remote sensors are a game changer. They balance temperatures room-by-room instead of relying on a single hallway reading, which finally made our home feel consistently comfortable. The smart scheduling and eco features work without constant tweaking, and I’ve already noticed more efficient heating and cooling.
One big bonus: I qualified for a utility rebate, which significantly reduced the out-of-pocket cost. Between that and the energy savings, it feels like this thermostat will pay for itself over time.
*I will note if you want to use Siri you will need a HomePod or HomePod mini for that feature.*
The display is clean and modern, the interface is intuitive, and it integrates smoothly with smart home platforms. I also appreciate the extra touches like air quality monitoring and occupancy sensing features that feel genuinely useful, not gimmicky.
Overall, it’s a well designed, reliable thermostat that delivers real value, especially if you take advantage of available rebates.

I only review products that are extraordinarily bad or incredibly good. This product merits the latter, not just for its programming and control features, but for outstanding customer service.
My dated HVAC system does not have a C wire, which is necessary to power most modern programmable thermostats. Fortunately, this top of the line ecobee thermostat comes with a hack, called a power extender kit. Unfortunately, the power extender kit is not an easy install. That’s where Ecobee‘s amazing customer service comes into play.
For more than an hour, the Ecobee’s customer service rep, using my digital photographs uploaded to the company’s portal, and with clear, highly skilled communication, walked me through the wiring process, not just at the newly mounted thermostat but also deep in the innards of my furnace to mount the power extender.
Keep in mind, time was of the essence, considering the furnace had to be shut down in early January in Chicago. We got it done in an hour or so.
Had Ecobee not been there to walk me through this, I would’ve had to remount the old, persnickety Nest thermostat given the winter time urgency, and call an HVAC guy. I doubt my handyman would’ve had the expertise to mount the power extender kit without help from the company.
The Ecobee with the power extender is not inexpensive but considering the time and cost of fish taping a C wire through the wall to connect to the old furnace, it’s a reasonable price.
If your furnace is like mine and has only four wires leading to the thermostat, chances are you need this.
Bottom line: an excellent product exceeded only by its outstanding customer service!
