I was disappointed. Actually take that back, I was beyond disappointed, I was downcast. The reason is because of a recent purchase of mine. Since my birthday was not that long ago, I decided to buy a few things for myself. While most of the items turned out to be awesome, there is one that I am pretty disappointed with. The item I am disappointed in is the smart thermostat. I have been wanting to improve my home’s heating & cooling comfort, & you can’t go wrong with a particularly modern, brand new technology Heating & Air Conditioning smart thermostat. I looked at all of the reviews & a lot of people were having enjoyable luck with theirs, so why was my Heating & Air Conditioning thermostat giving wrong studyings? I briefly wondered if it could be an issue with my heating plus A/C device, but that wouldn’t make sense, because I only started having issues after installing this new thermostat. My previous thermostat had issues as well, but I was used to those issues. Honestly, I just kind of figured that the programmable thermostat was old & messing up, which was even more reason why to get a new thermostat. Although I felt close to giving up, I first needed to get a professional’s opinion, & I am so cheerful I did! The professional heating plus A/C professional took one look at the smart thermostat & told me it wasn’t an issue with the smart thermostat at all, it was the sitement. The new thermostat was sited right next to a sunny window, & the sun shining on the thermostat was giving false studyings. That’s also why my previous thermostat also had issues.
