Our heating/cooling contractor recommended we upgrade our thermostat when we had new cooling and heating equipment installed. They use and install Nest thermostats. So we had one installed. Great upgrade from our previous non-programmable thermostat. Love it and love programming from the Nest app on my iPhone.
So far I have two Nest E thermostats in my two story home as well as a temperature sensor. They are easy to install and set up. The schedules are easy to set up as well. My electric company here in AZ has different prices for different times of use and it is extremely useful to set the schedule on these thermostats to save money during the higher cost time frames.
This product was easy to install. It learned our schedule fast and has started auto adjusting for use. It has saved us a lot of money on our electric bill.
Soooo much better than the original thermostat that was in this house when we moved in. It was a bear to install (older house) but once it was up and working, I love it. It's easy to use and very convenient. If you don't have one...you should get one.
