My husband and I have known about smart thermostats for a while. As newer homeowners, however, we have been trying to save our money for a number of upgrades, so we took our time when it came to purchasing a smart thermostat. When we had finally saved enough money, we went online and talked to a number of our friends in order to learn more about the various types of smart thermostats as well as their pros and cons. We learned that there are really fancy, expensive smart thermostats on the market that can essentially operate your heating and cooling system for you if you program them properly. There was one brand of smart thermostat that we researched that allegedly saved money and energy automatically as long as the proper information was programmed into it! A high quality smart thermostat like that would definite save us money after a few months. However, the price on that thermostat was a little steep, so my husband and I ended up choosing the next best smart thermostat for our home. The thermostat we chose actually could predict how long it would take our heating and cooling equipment to reach the temperature we wanted. It was able to adjust the times it operated in conjunction with the time it took our home to reach our desired temperature, which ended up saving us a great deal of money! Honestly, I wish that we would not have taken so long to purchase a smart thermostat for our new home. I think that if we had purchased one sooner, we would have saved even more money in terms of our heating and cooling costs!
