I have had a smart thermostat in my house for quite a while now and it has really served me well. However, recently the smart thermostat had seen its day and it broke down for good. I was trying to figure out if I wanted to get a brand new smart thermostat or just replace the smart thermostat with an older thermostat. That was when I remembered that I had an old dial thermostat that was still in the best and perfect working order. The old dial thermostat was almost as good as new. And since I knew everything there was to know about installing any kind of thermostat, I just took out the broken smart thermostat and put in the almost good as new old dial thermostat! I had the dial thermostat up and running within about 10 minutes time. That is how fast I can do this task. So because of this, I ended up saving myself a nice little chunk of change in having to invest in a smart thermostat again and then having to call the local heating and air conditioning company to send out a certified heat and a/c specialist to install the brand new smart thermostat that I may have bought. A smart thermostat is something that even though I can install the actual product, I would not be able to do the extra bits in programming it to work the apps that are on the computer and cell phone. So that was an extra cost I saved by going back to the old dial thermostat all by myself!
