We have a very old thermostat in our home that dates all the way back to the 50s, but my hubby Jack is of the mindset that if it’s not broken, don’t fix it! Well, we’ve lived in this house for the past 12 years and all that time, I’ve had to deal with this outdated thermostat. I believe if we got a modern smart thermostat, it would absolutely help to make our outdated house more energy efficient, but see, a smart thermostat would allow us to set the temperature in the house to assorted levels in certain rooms of the house. I’ve always thought that it makes no sense at all to keep the HVAC system cranking all afternoon just so we can come home to a heated or cooled house. It would be great if we could program the thermostat to come on an hour or so before we got home from work! Then the HVAC system would kick on at just the right time and it would save us tons of money, and there are all kinds of thermostats that you can choose from, depending on your family’s identifiable needs. I wish Jack would just see the wisdom in this and let me schedule an appointment with a local HVAC worker to come out to at least give us an estimate on a modern thermostat! We really could use one, even if our old, antique thermostat is still working just fine. I’m interested most in the smart thermostat!
