I have one of those most modern and very up to date smart thermostats in my home for my central heating and air conditioning system unit.
I have had this smart thermostat almost 6 months or so now.
And the other day I noticed a major issue with the smart thermostat. The timer that you program for it go on and off at a certain time was off by about 10 minutes. This was a problem and not normal. I knew at this point I had to do one of 2 things. The first would be to just cut my losses and go out to buy a brand new smart thermostat. The other would be to call the local heating and air conditioning company to send out a certified heat and a/c specialist to repair the timer and programmer of the smart thermostat that goes with my central heating and air conditioning system unit. I decided to call the local heating and air conditioning company first to see how much they would charge to come out and try to repair whatever was going on with my smart thermostat. And after them quoting the price I had just gave up and decided that it would be way cheaper to just go out to the store and buy a brand new smart thermostat and then bring it home and reinstall it myself. This would save me hundreds of dollars compared to what the local heating and air conditioning company wanted to come out and repair my smart thermostat’s programmer. It just was not worth it.
